I’m pretty sure you have to fire at least 4 igbts simultaneously and shortly there after all 6 to recreate the three phase sine wave relation ship due to winding the stator in delta. Energizing 1 phase will put the other two phases in series and in parallel with the energized phase…Right?
Hey mindset, can you please make a video to break down in high detail of what's the difference between a heat sink and a heat exchanger? Because there is no video to detail them so well and I'm having a hard time trying to find the information can you please make that video to tell us the differences please man? Thank you
Assuming this channel started as a side hustle, you must have extreme dedication to making the internet a library of knowledge as it should be. This is a one of a kind channel. Respect
I have been slowly learning basic electronics for years. Your simple video has taught me more about DC motors in the past 15 minutes than I've learned in years. Thanks.
@thabg007 can you please tell me how to run a brushless motor from a power supply and not from a battery ? I can't find this information anywhere ! What kind of power supply do i need ? I have a 2600 KV bldcmotor from aliexpress, i have the ESC and the blue tester used in those videos on youtube but i don't have a battery and i need to know how to make it work without a battery ! Please answer !
I still have my pulse siding solenoid motor that looks like a steam engine from high school it's very inefficient but looks like a piston going in and out of the copper wound core with a piece of steel on a crankshaft and simple mechanical switch on the side
I started years ago with a 50 in one electronics kit it had two transistors a bunch of resistors capacitors and several other things that's the first toy I stayed up all night playing with
The old brushed ones were actually pretty dang good (overengineered floor buffer motors basically), the stouter mechanical designs have only been recently matched by grintech and the All Axle motor. Brushless still rules of course, lol
The more i watch engineering mindset, the more i am convinced "its complicated" just means "I'm not smart enough to explain it" Not a single video on this channel is complicated or hard to understand and i love this channel for that reason
@Bob Sacamano Yeah, Skyler means when you ask your journeymen or who ever is above you in your career. The answer "it's complicated" can mean "I'm not smart enough to explain it"- Said some Journeymen. Everyone can learn and improve, but it means you can out grow your mentor fast when 9/10 their answer to you is... "its complicated"
There is also a BIG difference between explaining it in a prerecorded video, with all the time and editing and revision you want alongside animation and visual aid and having to extemporaneously explain it with no props
My first experience with a brushless DC motor came in 1978 when I built a floppy disc controller. The head positioning mechanism was driven by a brushless DC motor called a stepper motor. I can step the motor at a constant rate, or I could step the motor with acceleration, negative or positive. Steppers are marvelous devices that can accomplish things you couldn't do with a standard DC motor. For instance, you could hold the motor in a very specific position over a given track, and you can't do that with a standard DC motor. If you energize one coil it will lock the head in place and it will not move in or out.
There will always be a place for combustion motors. Especially in high demand situations. It's just not physically possible to get the same amount of work out of a battery powered machine compared to a combustion machine.
I'm a landscaper and I recently transitioned a bunch of my tools to a line of heavy duty brushless battery powered away from combustion engines. I'm blown away by the performance,remarkably strong-but what has most sold me is how much less upkeep they require. It has simplified my life a great deal. Hell, even the chainsaw blows my mind. It probably wouldn't serve a logger but godamb if it isnt more than enough for my purposes. Electric tools have come a long way.
I like rechargable but gas has its place. My Makita blower would suck down a 3 amp battery int he matter of just maybe 10m 15 tops. You have to run a 5-6 amp to get any decent time out of it. Gas has plenty of power and can run longer even though I hate the sound and smell.
I have 4 of these motors on my 2015 3DR Drone Quad-Copter. They are very powerful and have been working great for nearly 10 years! I earned my BSEE from NorthEastern in 1991 and still learned something here! Great video!
I’ve been flying fpv and racing rc cars for years….and i never knew exactly how this worked. You explained this sooo easily i fully get it now thank you!!

Great explanation, on my drone builds the esc, (speed control) is built into the flight control board these days. Years ago they were separate pcb's where you needed one for each of the motors.
Yeah it’s used primarily on HVAC systems rated at 20 SEER and above, the inverter/reactors are usually rated at 7.5kW. Almost all new mini split systems also use ECM/BLDC fan motors and compressors as well
speaking of really neat inverters, check out modern drone motor drivers, a.k.a. BL-heli ESCs sometimes. those have come a long way, from basic brushless speed controllers, as shown here, to sophisticated PWM'd 3-phase inverters, with more processing power then my first PC had.
I've been winding a decade. Great vid! The outrunners are interesting to wind, 14 pole 12 slot is like two split pole 3 phase motors in a row. The 10 pole 12 slot is like four 3 phase motors in a row . Many internal series and parallel combinations possible. I made tooling to wind them on my two pole powered winder. 70% time reduction for high voltage windings but not faster for low voltage because of cycle time resetting the stator on it vs horizontal vice tooling.
Very professional, I've seen these videos and worked with all motors for over 20 years, prior to chasing software nonsense. Where've I used BLDC motors? I was in automation/motion control and did applications in everything from manufacturing of knives, wood paneling to assembling of planes to candies. I miss it but once you're 40, you're out, and there's very little manufacturing anymore. Everything was custom and new when I was involved, now new is outsourcing to Shenzhen instead of Malaysia. Bitter? Yes.
By far the best teaching on brushless motors I have come across on RUclips. Thank you so much. Now I also have a good understanding on this technology.
These videos are so jam-packed with information that it should be incredibly daunting... in fact, info overload has been my number one barrier to getting more seriously into electronics. But somehow, these videos give the exact information I want in such a perfect order that it doesn't add any confounding questions or frazzle me, it's a freaking treasure trove... it's like when you drink coffee and all you get is the elevated focus and mood without any of the anxiety and heart jumpiness. These videos are the perfect cup of coffee of instructional RUclips videos about electrical engineering. That's my metaphor and I'm sticking with it.
The first time I had ever seen one was in 1977 when I bought my new stereo system when I graduated college. I got a Technics SL1400 turntable (I still have it). It is a direct drive turntable. When you lift the platter you can see a magnet ring under it which is the same thing as that outer casing that spins. And around the spindle shaft are the coil windings.
You really explained this well. Few people appreciate how fascinating this science really is. The tiniest little motor I have seen is in my drones. Amazing, and far superior to the larger, brushed motors in my other drones. Conversions to E-bikes are one of the best ways to learn the concepts of brushless motors. Of course, dealing with DIY robots, these motors have their uses, along with their cousins the servo motors. I have been playing around with these things for years, but when someone asks me to explain whats going on inside, I can never do it properly. You have been a great help to me, and thank you.
دمت گرم سید که اطلاعات جامع و کامل و مبسوطی ارایه میدی من خودم در دستگاه های پیچگوشتی شارژی جدید به کرات شاهد موتورهای براشلس هستم و همیشه برام تفاوت این نوع موتور با الباقی موتور DC جذاب بوده که با توضیحات شما کاملا توجیح شدم اوصیکم بتقولله و نظم امرکم 🤩
I really enjoy things like this. You have a great way of explaining things. Back when I was growing up we did not have the internet most definitely did not have computers. None of that stopped me from learning on how things work. At that time radio shack was a great place to find things that helped you to learn about electronics. They had different type of electrical kits that you put together and it explains what each part did. Every year they used to come out with a catalog and from that I could find different components and build things from scratch. As I was getting older my attention turned to other places. For a very long time I never messed around with electronics. All that changed about 10 years ago. I broke my back and I started looking for things I could do to keep me occupied and I made my way back to electronics. Of course everything is completely different than it was when I were growing up. I really enjoy your videos I have been a subscriber for a good bit of time and always enjoy watching new videos. Looking forward for watching your next video.
thank you. Me and a friend currently are in the beginning stages of a senior project (will be a senior next year) where we will be building a 3d printed bldc as we both are into rc and drone racing. We will most definitely put this video in the credits as it was quite helpfull in simplifying the complex mechanics behind the esc as it is vital for a bldc.
I have no words for this vid! It's a game changing on everything that I see on my hole life as an electric engineer. I wish I could study with all these material on my graduation course! Really thanks for this masterpiece!
I first came across them, as rack mounted fans that featured diminutive size compared to commutator designs in a location where synchronous motors could not have worked due to a lack of an A/C supply. You provided a description that was both wonderfully clear and devoid of any complexity. Essentially, the motor is always playing-chase-my-tail with the alternating fields generated by the different phases. I found it a fascinating use of techniques allowing relatively simply implementations.
This video was REALLY great! Perfect explanations as usual, so good in fact that I'm pretty sure people of any experience level would learn at least one thing from it!
And wow! I did not realize how complicated a brushless motor was. And to think we couldn't have done this without Tesla starting it off with the regular Motors. And his Motors were simple I could pretty much understand it change. But not these brushless motors plus, they are really complicated. As they say we live on the backs of our ancestors.
@@JourneyOnLife Yes, very much standing on the shoulders of giants! The technological gap seems huge when you consider that you could probably power a brushed motor with a sufficiently powerful 19th century voltaic pile, contrasted to the intelligence required inside the BLDC driver shown in the video!
I have a few RC cars. They all use brushless motors. I have an RC crawler that uses a sensored brushless motor with field orientation control. That motor works so smoothly for low speed crawling.
Just stumbled upon your channel whilst searching for information relating to relays and now I can't get enough. The lessons are clear, detailed, concise and easy to understand if you pay close attention. Love your content mate, cheers and keep up the good work! 👍🏼
They were being used in the 90s on some diesel engines. Cat used them on 3406 b and C engines with electronic controlled injection pump. One for rack control and one for timing control.
These type of motors are used on the compressor/vacuum pump in an oxygen concentrator. The low-speed torque is great for controlling the flow. Some of them feed the expelled nitrogen into the motor casing to cool the windings.
Carpentry, Masonry, Electrician, Plumber, Installers, and Tile Setters seems to be in very high demand. I wish Brilliant, which in my view is an upstanding company would teach these skills.
in 80s back in ussr my dad used to bring such small motors home from his work at the airport. I always wondered why they were so different from the usual dc motors and why they had this rotating metal cup inside.
I never knew how brushless motor worked. Thank you fir this idea explained clearly . All my Bosch power tools are brushless motor, they run smoother and use a bit longer as one go instead waiting to cool down every minute
Thank you! I appreciate the time you have taken to create the graphics! I learned visually and I'm amazed on the detail you include on your video graphics. I truly appreciate it. To me, you are the best of the best on RUclips explaining electrical current because of your graphic illustrations. Definitely subscribed!
Finally someone has said it clearly that the wire in the coil is insulation-coated. For a long time it had been a mystery to me why the current wouldn't travel the shortest way through the coil. Why do most of tutorials say 'just wind some wire into a coil, and you'll get a nice electric magnet' , assuming such important things as coating the wire are not worth mentioning?
In scale models I see often these BL motors. It would be nice to make a short part 2 for the innerrunner motors and sensored units used in scale crawlers and drift cars. Would help the RC community.
Motors for crawlers are actually great for drifters too, in higher KV choices like 2700 plus. Better torque density and smoother throttle response than race motors, better rpm lock.
Electric fan is a very good example of a brushless motors. I do electric fan repairs these days so that, now, i better understand how brushless motors work.
My $.02 worth: I have an electric drill (brush) purchased in 1987, made in USA, still going strong, still my go-to. Although a bit noisy it's taken a real beating after initially building a horse barn, rustic fences, etc. Eight years ago, purchased a brushless battery powered drill, same brand, made in China of course. Used it three times, had to toss it.
Love it. I keep binge watching your videos even if I have already viewed it. Because it is so educational and informative, it helps me remember things that I have forgotten. Kudos to you kind Sir. This video is also great Ilove it very much. Now I have the confidence to program a BLDC with an arduino thanks to you Sir.
Not sure how many everyday people realize that brushless motors are/were a game changer when it comes to overall power efficiency and in a way, power density when combined with lithium polymer batteries. My statement context being RC aircraft and cars/trucks, but of course larger applications too.... RC planes/helis went from underpowered, heavy, or lighter and only 5-10 minute of flight time carrying heavy NiCad/NiMH batteries and a maybe 50% efficient brushed motor to basically rockets that are only held back by your intentions. In my own case, my Parkzone SloV went from barely 10 minutes of anemic flight using a 380 brushed motor, to 15-20 minutes of looping, gliding, carrying a small camera, etc. all with a $30 lipo battery and cheap $40 "Tower Pro" outrunner motor & speed controller. The motor and ESC still work 16 years later, granted it was hibernating many years after I got married...😄. Absolutely amazing power as far as I was concerned back in 2006. :D
What an amazing video. I aspire to be, one day, such a great teacher as you are. Never seen anyone break down seemingly complicated things down to such easy to understand chunks. Thank you!
It was once stated, "If you can't explain it to a six year old and have them understand what you mean, then you don't understand the material well enough yourself. Go home, study more."
All that engineering for 5USD including shipping, thanks China! Great video :) I never managed to see the way of rotation with he "beeps" from the ECS, the datasheet says it's to know the battery strings number (it works from 2S to 4S so 2 to 4 "beeps").
I got mine from amazon, it was a premium for next day delivery but still incredible value what what goes into it. If you film the motor with your phone in slow motion you can see it produce the beeps through vibration
The company I work for just started using very large brushless motors for stack fans. These fans are generally used in large arrays atop buildings as part of the climate control systems. These motors are around 2 feet in circumference by around 13 inches front to back. and have attached to their shafts a large aluminum fan blade.
BLDC motors are used in electric RC aircrafts, ROVs, electric cars (yes, they're just bigger), hoverboards, electric bicycles and other such applications where a reliable, water and wear resistant motor is needed. Also, when you power up the ESC, it makes those noises to also tell you information about the current configuration. The ascending tune tells you that the ESC is online and ready to arm. The next beeps tell you what type of battery is connected. Three beeps means 3S 11.1V lithium battery is connected. Four beeps means a 4S battery etc. There might be a second set of beeps to tell you additional information about the ESC. The next beeps alert you that the ESC is armed. This is important, because those drone propellers can easily cut you. When you hear the arming beeps, always remember to disarm before interacting with the motors.
Interesting, it's a good thing that this was published right now. I have one question but it's not related to the video: what type of inductor is the one that looks like a resistor? Thanks in advance, Paul!

I found this video when I was looking at drones to figure out what to look for and what to get and had no idea what the difference in the motors was. But I’m a nerd and learned much more than I needed and I love it. Figured out what to get and learned about brushed and brushless motors for anything outside of drones. 👍🏼
Great video, but this topic considers only one type of control algorithm, sensor less 6-step which has some disadvantages. This algorithm is the most basic and closely emulates the mechanical commutator. Sensored Direct Torque Control and Field Oriented Control are the methods of choice for professional motor applications. They don't have problems at zero RPM. I would have cut out the whole section about the interface between the motor controller and the controlling device. 1-2ms PWM is only used in the RC hobby. And even that is obsolete now, replaced with more advanced protocols like OneShot and Dshot. Motor controllers in other applications (eBikes, EVs, industry) will use analog voltages or digital communication over RS232, RS485, CANbus, etc)
Roger Technology has revolutionized the gate motor industry with digital brushless operators, I’m learning it now and your comment makes so much sense. An analog controller will under utilize the true benefits of a brushless motor. Am I on the right path there?
@@jarkstt control over a "BLDC" can get quite advanced. So the controllers should be optimized for a specific job. Odrive uses BLDC motors with tight positional control in a closed loop (feedback from a high resolution encoder. The interface for that is similar to stepper motor controllers since the target application is CNC. EV's on the other hand do not need tight positional control, instead the throttle controls the torque of the motor, which indirectly controls the velocity of the vehicle, it's a second-order system with the pilot or driver being the thing that closes the loop (driving). This application requires the motor operate in all 4 quadrants (spins both ways, and with regenerative braking) With FOC you specify the desired torque and the controller adjusts the current in the phases to maintain generated field 90° ahead of the rotor and uses a PI control loop to regulate the current to achieve desired torque. Then optionally another control loop governs this whole system to regulate speed. This works until the motor reaches a speed where the back EMF equals or exceeds the supply voltage. Then the requested torque can no longer be achieved since it would require either higher voltage or field weakening, which some BLDCs can do by increasing the space between the rotor magnets and stator, common on the solar car motors. Another method of field weakening to increase max speed is to change the angle of the stator field so as to cancel out some of the flux from the permanent magnets, but this consumes more power and is inefficient.
@@MrXjoeharperx my point is to generalize the video on BLDC control rather than focus on a cheap obsolete technology and its interface from Ali express or Amazon that used to be used for a specific RC hobby 10 years ago and is not really relevant anymore.
Great video! I'm curious about one thing, though-- as the magnetic field rotates due to the constant pushing and pulling of polarity, is there a difference between the pushing vs. the pulling force? Just wondering if one is stronger than the other or if the speed of rotation renders any difference to be negligible...
If the currency is the same (which should be at this moment) and distance is the same (which is basic requirement for creating an engine) there should be no difference in force between push and pull forces as they are just reactions to the same physical values but with opposite vector of the force. Correct me if I'm wrong :)
The motors only work on pulling forces of magnetic North South pairs, not repulsion of magnetic north north or SS. The Flux of the tooth/magnet pairs form a closed magnetic circuit with each other via back iron and airgap coupling.
60 year old electronics guy here. Back in the day these motors were called “Three Phase Synchronous Motors”….weren’t as torquey or small, but we did not have the strong samarium-cobalt magnets back then….but the principles were the same.I feel that the term, “Brushless DC Motor” is just the invention of marketing people to make you think you have something “new”, but in gact it has been around since about 1890! Not being a “software” person, it seems like the Arduino is a “Sledgehammer to smash a Wallnut”. Far easier to use simple hardware to generate PWM from a voltage off a pot wiper. Construct a 50Hz sawtooth generstor from a constant current source and a capacitor in series, watch the ramp on the capacitor with a comparator and use a voltage into the other input of the comparator to set where the capacitor is discharged…(the output of the comparator controls a transistor in parallel with the capacitor and is switched on by the comparator to discharge the capacitor when the ramp reaches the other comparator input voltage.) Inthink a simple old 555 can be configured to do all of this with the exeption of the current source. Then use a second comparator with one input to the ramp capacitor…i.e. the 50Hz sawtooth, snd the other input to the pot wiper…its output is now the PWM you seek. No computer, USB transfer or orogramming required. I was waiting for the description of function of the PWM to Three Phase “H” brodge driver, but i never came! Note: coils of wire around iron cores create MAGNETIC Fields, not ELECTROmsgnetic fields. An electromsgnetic field is a radio wave or light wave…or gamma rays..i.e. light, not msgnitisim. Incsn understand how this failing of the English Language can occur…thibk ing that because a coil around an iron core is an ELECTROmagnet, it creates an electromagnetic field..but not really, yes, for an instant at power up nd st turn off..(an A.M. radio nearby will “hear” it), but in the steady energised witn DC phase there is no electromsgnetic radiation emitted, just a constant magnetic field like that of a permanent magnet.
A huge change for me was in my 1/10 scale R/C car., to keep brushed motors operating at their peak , you needed a mini lathe to keep the brush interface perfectly smooth...
Clear, concise, builds on each previous segment, and got me interested to know more. You've got a tremendous style and packed a ton into a short video. Started the video just wanting a short explanation, ended subscribing!
I have a request Paul!! I belong to Marine Engineering and its a set of unique mechanics and machineries hard to understand and relate with each other, although its a small floating world in itself where we do all the maintenance repair and operation, it would be helpful if you make videos on some of the topics related to them, it would be amazing and appreciative!!
Very informative! I have a brushless motor on my Lowrance Ghost trolling motor. It’s noticeably more powerful and efficient than the old brushed motor I used previously.
Good evening, this video on brushless motors is one of the best I've ever seen. I would like to ask a few questions if possible: What happens if one of the three brushless motor power cables is interrupted? In this case, does the driver or ESC that supplies the alternating voltages block or does it continue to supply currents on the two cables left intact? Can fuses (one on each power cable) be put on the brushless motor, or are there any contraindications?
Fantastic video. Epicly so. I watched and paused and rewound every few seconds, so I could absorb as much as possible. I'm generally familiar, even having build a small motor as a child, but this video is flawless. I watch most videos in 1.5-2.0 speed. Not this one. Thanks for stuffing it full of info.
"they use three phase electricity" - most efficient explanation ever. Rest of the video after 10 secs is just a bonus. Thanks. (I'm assuming transistors in the ESC keep switching to the next set of coils in the 3 phases, keeping the rotor chasing the force?
don't get me wrong; I mean I learned stuff from it that quick. I'm watching the rest too and love the animations, being also very basic level in electronics and wanting to make my own simple motor and generator as proof of concept. Thanks!
I own several Laser Etching machines that rely on strong brushless DC Motors to move the Laser Head in an X/Y direction. Next level up in the CNC Machining field adds Z for up/down movement of a powerful brushless DC motor, to either adjust the focal distance of a Laser Head - or provide depth cutting to a CNC Tool Head, some which are monstrously powerful, for cutting metals. The intrinsic higher torque over traditional dc motors is an obvious reason for Brushless DC Motors being used, up to the highest levels of Industrial manufacturing of raw billets of some extremely hard metals. Titans of CNC is a prime example of leading edge
There must be 2.8 million very clever people on the the 25th of January 2023 if they could undrestand and follow this from start to finish. I struggled. Science is like a MAGIC trick. You see it but you don't. Thanks for the video, Genius.
40 years ago, Sony broadcast 1” videotape machines used large brushless motors for the reel drives, the upper rotary head drum, and the capstan. These motors are particularly good for this application because it’s essential to not only control the speed, but the angular position.
I race rc cars and we use brushless motors and esc's all the time that is how our electric cars work. But I have always wondered how the motors were made and this is very cool
Thank you. Now I understand why my drone makes that little configuration sound before start up. Awesome technology. Old retired NYD (not yet dead) guy.
I made the mistake of getting a brush motor trimmer to use with my power rotary scissors. This created some interesting burning smells, and killed the battery in 15 minutes. I got the more expensive, brushless version - same battery etc. and good lord - WHAT a difference! The battery lasts over an hour now, the speed throttle is more precise, and of course - no burning smell. Definitely more torque. I’m going to be sure to get only brushless tools from now on.
My Ryobi riding lawn mower uses a 48 volt/100 AH brushless motor system. Quiet with more torque than the gas powered rider it replaces. I use it at a cabin in the middle of nowhere, and charge it with an off-grid solar panel system.
@@gabedarrett1301 I'm not sure what you're asking. improve in what way? The development engineers design the driver work the best they can. With the components we have today and the experience, there isn't much room for improvement.
BRO ONG I LOVE YOUR VIDSSS! Honestly like it’s so detailed and you explain stuff so we’ll!!! Like I don’t normally comment but I had to cuz like it’s satisfying how detailed and well these vids are!!!
My first time being exposed to brushless motors was a number of years ago when I use to build and fly drones (I need to get back into that hobby again). I also have two bigguns on my all-terrain electric skateboard. Now I'm learning about it because I'm an electrical apprentice. Good stuff!

My first experience with a brushless DC motor came in 1978 when I built a floppy disc controller. The head positioning mechanism was driven by a brushless DC motor called a stepper motor. I can step the motor at a constant rate, or I could step the motor with acceleration, negative or positive. Steppers are marvelous devices that can accomplish things you couldn't do with a standard DC motor. For instance, you could hold the motor in a very specific position over a given track, and you can't do that with a standard DC motor. If you energize one coil it will lock the head in place and it will not move in or out.
My battery powered hedge trimmer uses BLDC motor, they are impressively powerful. No need for noisy, vibrating petrol trimmers now.
There will always be a place for combustion motors. Especially in high demand situations. It's just not physically possible to get the same amount of work out of a battery powered machine compared to a combustion machine.

I'm a landscaper and I recently transitioned a bunch of my tools to a line of heavy duty brushless battery powered away from combustion engines.
I'm blown away by the performance,remarkably strong-but what has most sold me is how much less upkeep they require. It has simplified my life a great deal.
Hell, even the chainsaw blows my mind. It probably wouldn't serve a logger but godamb if it isnt more than enough for my purposes.
Electric tools have come a long way.
I like rechargable but gas has its place. My Makita blower would suck down a 3 amp battery int he matter of just maybe 10m 15 tops. You have to run a 5-6 amp to get any decent time out of it. Gas has plenty of power and can run longer even though I hate the sound and smell.
I have 4 of these motors on my 2015 3DR Drone Quad-Copter. They are very powerful and have been working great for nearly 10 years! I earned my BSEE from NorthEastern in 1991 and still learned something here! Great video!
DUDE!!! Sooooo comprehensive and NOTHING confusingly extra.
Multiple thanks. Well crafted video

I’ve been flying fpv and racing rc cars for years….and i never knew exactly how this worked. You explained this sooo easily i fully get it now thank you!!
@thabg007 can you please tell me how to run a brushless motor from a power supply and not from a battery ? I can't find this information anywhere ! What kind of power supply do i need ? I have a 2600 KV bldcmotor from aliexpress, i have the ESC and the blue tester used in those videos on youtube but i don't have a battery and i need to know how to make it work without a battery ! Please answer !
Great explanation, on my drone builds the esc, (speed control) is built into the flight control board these days. Years ago they were separate pcb's where you needed one for each of the motors.
I believe Bldc motors are used in the newer high efficiency ac system compressors. Along with some really neat high amperage inverter technology.
Yeah it’s used primarily on HVAC systems rated at 20 SEER and above, the inverter/reactors are usually rated at 7.5kW. Almost all new mini split systems also use ECM/BLDC fan motors and compressors as well
My firend why you say tings dat everyone knowings? No my firend no. Very long time for commenting. No smile oke?
speaking of really neat inverters, check out modern drone motor drivers, a.k.a. BL-heli ESCs sometimes. those have come a long way, from basic brushless speed controllers, as shown here, to sophisticated PWM'd 3-phase inverters, with more processing power then my first PC had.
@@Ucceah yeah I thought of that too late to add, but you are spot on; the new inverter tech is really something.
I'm an old motor and armature winder for some 50 odd years. I can honestly say I found this video interesting.
Thank you.
I've been winding a decade. Great vid! The outrunners are interesting to wind, 14 pole 12 slot is like two split pole 3 phase motors in a row. The 10 pole 12 slot is like four 3 phase motors in a row . Many internal series and parallel combinations possible.
I made tooling to wind them on my two pole powered winder. 70% time reduction for high voltage windings but not faster for low voltage because of cycle time resetting the stator on it vs horizontal vice tooling.
You spin me right round baby right round. 😂
The animation and breakdown of all the working components are extremely well done. Thank you for sharing
Very professional, I've seen these videos and worked with all motors for over 20 years, prior to chasing software nonsense. Where've I used BLDC motors? I was in automation/motion control and did applications in everything from manufacturing of knives, wood paneling to assembling of planes to candies. I miss it but once you're 40, you're out, and there's very little manufacturing anymore. Everything was custom and new when I was involved, now new is outsourcing to Shenzhen instead of Malaysia. Bitter? Yes.
Dumbfounded by how smart and generous you are with the knowledge and dedication to make these videos possible. Salute and respect your whole team.
By far the best teaching on brushless motors I have come across on RUclips. Thank you so much. Now I also have a good understanding on this technology.
These videos are so jam-packed with information that it should be incredibly daunting... in fact, info overload has been my number one barrier to getting more seriously into electronics. But somehow, these videos give the exact information I want in such a perfect order that it doesn't add any confounding questions or frazzle me, it's a freaking treasure trove... it's like when you drink coffee and all you get is the elevated focus and mood without any of the anxiety and heart jumpiness. These videos are the perfect cup of coffee of instructional RUclips videos about electrical engineering. That's my metaphor and I'm sticking with it.
The first time I had ever seen one was in 1977 when I bought my new stereo system when I graduated college. I got a Technics SL1400 turntable (I still have it). It is a direct drive turntable. When you lift the platter you can see a magnet ring under it which is the same thing as that outer casing that spins. And around the spindle shaft are the coil windings.
I still have mine too. I've seen the magnets, but didn't know this is how it worked. Thanks for sharing.
I just studied all this at college this year, and believe me this guy does it better!
You really explained this well. Few people appreciate how fascinating this science really is. The tiniest little motor I have seen is in my drones. Amazing, and far superior to the larger, brushed motors in my other drones. Conversions to E-bikes are one of the best ways to learn the concepts of brushless motors. Of course, dealing with DIY robots, these motors have their uses, along with their cousins the servo motors. I have been playing around with these things for years, but when someone asks me to explain whats going on inside, I can never do it properly. You have been a great help to me, and thank you.
دمت گرم سید که اطلاعات جامع و کامل و مبسوطی ارایه میدی
من خودم در دستگاه های پیچگوشتی شارژی جدید به کرات شاهد موتورهای براشلس هستم و همیشه برام تفاوت این نوع موتور با الباقی موتور DC جذاب بوده که با توضیحات شما کاملا توجیح شدم
اوصیکم بتقولله و نظم امرکم 🤩
I really enjoy things like this. You have a great way of explaining things. Back when I was growing up we did not have the internet most definitely did not have computers. None of that stopped me from learning on how things work.
At that time radio shack was a great place to find things that helped you to learn about electronics. They had different type of electrical kits that you put together and it explains what each part did.
Every year they used to come out with a catalog and from that I could find different components and build things from scratch.
As I was getting older my attention turned to other places. For a very long time I never messed around with electronics. All that changed about 10 years ago. I broke my back and I started looking for things I could do to keep me occupied and I made my way back to electronics. Of course everything is completely different than it was when I were growing up.
I really enjoy your videos I have been a subscriber for a good bit of time and always enjoy watching new videos.
Looking forward for watching your next video.
thank you. Me and a friend currently are in the beginning stages of a senior project (will be a senior next year) where we will be building a 3d printed bldc as we both are into rc and drone racing. We will most definitely put this video in the credits as it was quite helpfull in simplifying the complex mechanics behind the esc as it is vital for a bldc.
I have no words for this vid! It's a game changing on everything that I see on my hole life as an electric engineer. I wish I could study with all these material on my graduation course! Really thanks for this masterpiece!
I first came across them, as rack mounted fans that featured diminutive size compared to commutator designs in a location where synchronous motors could not have worked due to a lack of an A/C supply. You provided a description that was both wonderfully clear and devoid of any complexity. Essentially, the motor is always playing-chase-my-tail with the alternating fields generated by the different phases. I found it a fascinating use of techniques allowing relatively simply implementations.
This video was REALLY great! Perfect explanations as usual, so good in fact that I'm pretty sure people of any experience level would learn at least one thing from it!
And wow! I did not realize how complicated a brushless motor was. And to think we couldn't have done this without Tesla starting it off with the regular Motors. And his Motors were simple I could pretty much understand it change. But not these brushless motors plus, they are really complicated. As they say we live on the backs of our ancestors.
@@JourneyOnLife Yes, very much standing on the shoulders of giants! The technological gap seems huge when you consider that you could probably power a brushed motor with a sufficiently powerful 19th century voltaic pile, contrasted to the intelligence required inside the BLDC driver shown in the video!
True, it's a perfect explanation as usual
Yah ...I learned one thing - don't watch these videos; they make my head hurt & I understand just how dum I am !!
can confirm
I have a few RC cars. They all use brushless motors. I have an RC crawler that uses a sensored brushless motor with field orientation control. That motor works so smoothly for low speed crawling.
Just stumbled upon your channel whilst searching for information relating to relays and now I can't get enough. The lessons are clear, detailed, concise and easy to understand if you pay close attention. Love your content mate, cheers and keep up the good work! 👍🏼
Watch the adds... this guy is teaching principles in 15 minutes that took a professional an entire semester to teach.
They were being used in the 90s on some diesel engines. Cat used them on 3406 b and C engines with electronic controlled injection pump. One for rack control and one for timing control.
These type of motors are used on the compressor/vacuum pump in an oxygen concentrator. The low-speed torque is great for controlling the flow. Some of them feed the expelled nitrogen into the motor casing to cool the windings.
You are the best - the animations showing where the current flow is excellent. Your videos make a difference.
Carpentry, Masonry, Electrician, Plumber, Installers, and Tile Setters seems to be in very high demand. I wish Brilliant, which in my view is an upstanding company would teach these skills.
in 80s back in ussr my dad used to bring such small motors home from his work at the airport. I always wondered why they were so different from the usual dc motors and why they had this rotating metal cup inside.
I remember the time i disassembled Mig-17 hyroscope unit...and thouse 2 phase 400Hz small engines called Did-0,5! It happened 30 years ago
I never knew how brushless motor worked. Thank you fir this idea explained clearly .
All my Bosch power tools are brushless motor, they run smoother and use a bit longer as one go instead waiting to cool down every minute
Thank you! I appreciate the time you have taken to create the graphics! I learned visually and I'm amazed on the detail you include on your video graphics. I truly appreciate it. To me, you are the best of the best on RUclips explaining electrical current because of your graphic illustrations. Definitely subscribed!
Finally someone has said it clearly that the wire in the coil is insulation-coated. For a long time it had been a mystery to me why the current wouldn't travel the shortest way through the coil. Why do most of tutorials say 'just wind some wire into a coil, and you'll get a nice electric magnet' , assuming such important things as coating the wire are not worth mentioning?
It needs to be stated that the copper winding wire must be lacquered to insulate it. In a graphic you can't see whether it's insulated or not.
In scale models I see often these BL motors. It would be nice to make a short part 2 for the innerrunner motors and sensored units used in scale crawlers and drift cars. Would help the RC community.
Holmes hobby is where you should look for your answers. The man is solid gold in many ways. There are many videos he has made on different levels
@@chriscord6524 hey, small world! Thanks for the recommendation of @holmeshobbies
Motors for crawlers are actually great for drifters too, in higher KV choices like 2700 plus. Better torque density and smoother throttle response than race motors, better rpm lock.
Completely fascinated with this video.
I've been playing with Arduino for years, your videos just gave me a bunch of ideas.
Thanks 😊
Till now I have not use BLDC motor but after watching this video I will definitely use BLDC motor 🙂
Thanx for this video!
This is such a well detailed yet easy to understand video. Masterpiece!
Electric fan is a very good example of a brushless motors. I do electric fan repairs these days so that, now, i better understand how brushless motors work.
I've always been fascinated by PWM, 6-pulse and 6-step since my first year in college .. amazingly explained !
Do universal motors next !
I use brushless motors in my DeWalt cordless tools.
They are powerful and always operate reliably.
Wow, great detail and presentation. I thought I knew everything about brushless motors. Great job.
My $.02 worth: I have an electric drill (brush) purchased in 1987, made in USA, still going strong, still my go-to. Although a bit noisy it's taken a real beating after initially building a horse barn, rustic fences, etc. Eight years ago, purchased a brushless battery powered drill, same brand, made in China of course. Used it three times, had to toss it.
Love it. I keep binge watching your videos even if I have already viewed it. Because it is so educational and informative, it helps me remember things that I have forgotten. Kudos to you kind Sir. This video is also great Ilove it very much. Now I have the confidence to program a BLDC with an arduino thanks to you Sir.
Not sure how many everyday people realize that brushless motors are/were a game changer when it comes to overall power efficiency and in a way, power density when combined with lithium polymer batteries. My statement context being RC aircraft and cars/trucks, but of course larger applications too.... RC planes/helis went from underpowered, heavy, or lighter and only 5-10 minute of flight time carrying heavy NiCad/NiMH batteries and a maybe 50% efficient brushed motor to basically rockets that are only held back by your intentions. In my own case, my Parkzone SloV went from barely 10 minutes of anemic flight using a 380 brushed motor, to 15-20 minutes of looping, gliding, carrying a small camera, etc. all with a $30 lipo battery and cheap $40 "Tower Pro" outrunner motor & speed controller. The motor and ESC still work 16 years later, granted it was hibernating many years after I got married...😄. Absolutely amazing power as far as I was concerned back in 2006. :D
What an amazing video.
I aspire to be, one day, such a great teacher as you are. Never seen anyone break down seemingly complicated things down to such easy to understand chunks.
Thank you!
It was once stated, "If you can't explain it to a six year old and have them understand what you mean, then you don't understand the material well enough yourself. Go home, study more."
The visualizations for milliseconds of activity got me understanding everything more than I EVER have before.
All that engineering for 5USD including shipping, thanks China!
Great video :)
I never managed to see the way of rotation with he "beeps" from the ECS, the datasheet says it's to know the battery strings number (it works from 2S to 4S so 2 to 4 "beeps").
I got mine from amazon, it was a premium for next day delivery but still incredible value what what goes into it. If you film the motor with your phone in slow motion you can see it produce the beeps through vibration
Hi there! Do you have a link to the thing from china? :)
@@rubenoseapachi "1000kV motor on AliExpress"
The company I work for just started using very large brushless motors for stack fans. These fans are generally used in large arrays atop buildings as part of the climate control systems. These motors are around 2 feet in circumference by around 13 inches front to back. and have attached to their shafts a large aluminum fan blade.
This is actually fascinating.
4:52 The current takes all available paths, the strongest being the one with least resistance.
BLDC motors are used in electric RC aircrafts, ROVs, electric cars (yes, they're just bigger), hoverboards, electric bicycles and other such applications where a reliable, water and wear resistant motor is needed. Also, when you power up the ESC, it makes those noises to also tell you information about the current configuration. The ascending tune tells you that the ESC is online and ready to arm. The next beeps tell you what type of battery is connected. Three beeps means 3S 11.1V lithium battery is connected. Four beeps means a 4S battery etc. There might be a second set of beeps to tell you additional information about the ESC. The next beeps alert you that the ESC is armed. This is important, because those drone propellers can easily cut you. When you hear the arming beeps, always remember to disarm before interacting with the motors.
Interesting, it's a good thing that this was published right now.
I have one question but it's not related to the video: what type of inductor is the one that looks like a resistor?
Thanks in advance, Paul!
I'll cover that in the upcoming video,

I found this video when I was looking at drones to figure out what to look for and what to get and had no idea what the difference in the motors was. But I’m a nerd and learned much more than I needed and I love it. Figured out what to get and learned about brushed and brushless motors for anything outside of drones. 👍🏼
Great video, but this topic considers only one type of control algorithm, sensor less 6-step which has some disadvantages. This algorithm is the most basic and closely emulates the mechanical commutator. Sensored Direct Torque Control and Field Oriented Control are the methods of choice for professional motor applications. They don't have problems at zero RPM.
I would have cut out the whole section about the interface between the motor controller and the controlling device. 1-2ms PWM is only used in the RC hobby. And even that is obsolete now, replaced with more advanced protocols like OneShot and Dshot. Motor controllers in other applications (eBikes, EVs, industry) will use analog voltages or digital communication over RS232, RS485, CANbus, etc)
Roger Technology has revolutionized the gate motor industry with digital brushless operators, I’m learning it now and your comment makes so much sense. An analog controller will under utilize the true benefits of a brushless motor. Am I on the right path there?
You have to walk before you can run, there's no sense in confusing people that are trying to grasp the basic concepts of this.
@@jarkstt control over a "BLDC" can get quite advanced. So the controllers should be optimized for a specific job. Odrive uses BLDC motors with tight positional control in a closed loop (feedback from a high resolution encoder. The interface for that is similar to stepper motor controllers since the target application is CNC.
EV's on the other hand do not need tight positional control, instead the throttle controls the torque of the motor, which indirectly controls the velocity of the vehicle, it's a second-order system with the pilot or driver being the thing that closes the loop (driving). This application requires the motor operate in all 4 quadrants (spins both ways, and with regenerative braking) With FOC you specify the desired torque and the controller adjusts the current in the phases to maintain generated field 90° ahead of the rotor and uses a PI control loop to regulate the current to achieve desired torque. Then optionally another control loop governs this whole system to regulate speed. This works until the motor reaches a speed where the back EMF equals or exceeds the supply voltage. Then the requested torque can no longer be achieved since it would require either higher voltage or field weakening, which some BLDCs can do by increasing the space between the rotor magnets and stator, common on the solar car motors. Another method of field weakening to increase max speed is to change the angle of the stator field so as to cancel out some of the flux from the permanent magnets, but this consumes more power and is inefficient.
@@MrXjoeharperx my point is to generalize the video on BLDC control rather than focus on a cheap obsolete technology and its interface from Ali express or Amazon that used to be used for a specific RC hobby 10 years ago and is not really relevant anymore.
@@power-max hi, i want to make electric starter for motorcycle engine, is cheap chinese esc etc enough for it ?
Onewheel is the most fun use of brushless motors I have encountered
Great video! I'm curious about one thing, though-- as the magnetic field rotates due to the constant pushing and pulling of polarity, is there a difference between the pushing vs. the pulling force? Just wondering if one is stronger than the other or if the speed of rotation renders any difference to be negligible...
If the currency is the same (which should be at this moment) and distance is the same (which is basic requirement for creating an engine) there should be no difference in force between push and pull forces as they are just reactions to the same physical values but with opposite vector of the force.
Correct me if I'm wrong :)
The motors only work on pulling forces of magnetic North South pairs, not repulsion of magnetic north north or SS. The Flux of the tooth/magnet pairs form a closed magnetic circuit with each other via back iron and airgap coupling.
60 year old electronics guy here. Back in the day these motors were called “Three Phase Synchronous Motors”….weren’t as torquey or small, but we did not have the strong samarium-cobalt magnets back then….but the principles were the same.I feel that the term, “Brushless DC Motor” is just the invention of marketing people to make you think you have something “new”, but in gact it has been around since about 1890!
Not being a “software” person, it seems like the Arduino is a “Sledgehammer to smash a Wallnut”. Far easier to use simple hardware to generate PWM from a voltage off a pot wiper. Construct a 50Hz sawtooth generstor from a constant current source and a capacitor in series, watch the ramp on the capacitor with a comparator and use a voltage into the other input of the comparator to set where the capacitor is discharged…(the output of the comparator controls a transistor in parallel with the capacitor and is switched on by the comparator to discharge the capacitor when the ramp reaches the other comparator input voltage.) Inthink a simple old 555 can be configured to do all of this with the exeption of the current source.
Then use a second comparator with one input to the ramp capacitor…i.e. the 50Hz sawtooth, snd the other input to the pot wiper…its output is now the PWM you seek. No computer, USB transfer or orogramming required.
I was waiting for the description of function of the PWM to Three Phase “H” brodge driver, but i never came!
Note: coils of wire around iron cores create MAGNETIC Fields, not ELECTROmsgnetic fields. An electromsgnetic field is a radio wave or light wave…or gamma rays..i.e. light, not msgnitisim. Incsn understand how this failing of the English Language can occur…thibk ing that because a coil around an iron core is an ELECTROmagnet, it creates an electromagnetic field..but not really, yes, for an instant at power up nd st turn off..(an A.M. radio nearby will “hear” it), but in the steady energised witn DC phase there is no electromsgnetic radiation emitted, just a constant magnetic field like that of a permanent magnet.
Im a forklift Technician, we use Brushless motors on alot of the Forklift and man up units.
A huge change for me was in my 1/10 scale R/C car., to keep brushed motors operating at their peak , you needed a mini lathe to keep the brush interface perfectly smooth...
Great video. Thank you for giving me a much better understanding of brushless dc motors. Every other vid just over complicated things
Wow this was an insanely clear explanation of how BLDC, ESC and PWM works. I'm trying to build a hobby drone so this is really useful info
Clear, concise, builds on each previous segment, and got me interested to know more. You've got a tremendous style and packed a ton into a short video. Started the video just wanting a short explanation, ended subscribing!
I have a request Paul!! I belong to Marine Engineering and its a set of unique mechanics and machineries hard to understand and relate with each other, although its a small floating world in itself where we do all the maintenance repair and operation, it would be helpful if you make videos on some of the topics related to them, it would be amazing and appreciative!!
Very informative! I have a brushless motor on my Lowrance Ghost trolling motor. It’s noticeably more powerful and efficient than the old brushed motor I used previously.
Brushless motors are becoming very popular in competition robotics such as FIRST. Namely the NEO and Falcon motors.
please don't stop making videos - one of the best RUclips learning experience anyone will ever get 👍
These are very much becoming the norm in combat robotics, like NHRL, BuggleBots, RoboGames, Bristol Bot Builders Bug Brawl, and BattleBots.
Best brushless DC motor explanation on RUclips!
Good evening, this video on brushless motors is one of the best I've ever seen.
I would like to ask a few questions if possible:
What happens if one of the three brushless motor power cables is interrupted?
In this case, does the driver or ESC that supplies the alternating voltages block or does it continue to supply currents on the two cables left intact?
Can fuses (one on each power cable) be put on the brushless motor, or are there any contraindications?
Just purchased a new Garmin Force trolling motor for my fishing boat……brushless, which provides more torque with the same battery load.
I have brushless motors in my Bosch 12v 3/8 drive Drill and Driver. Awesome tools !
Fantastic video. Epicly so. I watched and paused and rewound every few seconds, so I could absorb as much as possible. I'm generally familiar, even having build a small motor as a child, but this video is flawless. I watch most videos in 1.5-2.0 speed. Not this one. Thanks for stuffing it full of info.
Man.. I always trying looking for this kinda video for almost 5 years, huge thanks for your help
So good... No broken English, easy diagrams, and useful advice.... Liked and subscribed.
"they use three phase electricity" - most efficient explanation ever. Rest of the video after 10 secs is just a bonus. Thanks. (I'm assuming transistors in the ESC keep switching to the next set of coils in the 3 phases, keeping the rotor chasing the force?
don't get me wrong; I mean I learned stuff from it that quick. I'm watching the rest too and love the animations, being also very basic level in electronics and wanting to make my own simple motor and generator as proof of concept. Thanks!
Wow!! That is beautiful! I liked the last view without the light. You see the grain of the wood.
I own several Laser Etching machines that rely on strong brushless DC Motors to move the Laser Head in an X/Y direction. Next level up in the CNC Machining field adds Z for up/down movement of a powerful brushless DC motor, to either adjust the focal distance of a Laser Head - or provide depth cutting to a CNC Tool Head, some which are monstrously powerful, for cutting metals. The intrinsic higher torque over traditional dc motors is an obvious reason for Brushless DC Motors being used, up to the highest levels of Industrial manufacturing of raw billets of some extremely hard metals. Titans of CNC is a prime example of leading edge
Brilliant, literally!!! Knowing how to make such a simple motor could be very helpful in many situations!!!
There must be 2.8 million very clever people on the the 25th of January 2023 if they could undrestand and follow this from start to finish. I struggled. Science is like a MAGIC trick. You see it but you don't. Thanks for the video, Genius.
40 years ago, Sony broadcast 1” videotape machines used large brushless motors for the reel drives, the upper rotary head drum, and the capstan. These motors are particularly good for this application because it’s essential to not only control the speed, but the angular position.
I race rc cars and we use brushless motors and esc's all the time that is how our electric cars work.
But I have always wondered how the motors were made and this is very cool
I ever wondered why some controllers don't need a hall sensor ... never thought the controller measured the Back EMF ... thanks for this great video!
Haven't seen something more complicated than this for me....kudos ❤
Fantastic tutorial! After following your video I managed to get my ESC to work exactly as I wanted it. Thank you
Thank you. Now I understand why my drone makes that little configuration sound before start up. Awesome technology. Old retired NYD (not yet dead) guy.
I made the mistake of getting a brush motor trimmer to use with my power rotary scissors. This created some interesting burning smells, and killed the battery in 15 minutes. I got the more expensive, brushless version - same battery etc. and good lord - WHAT a difference! The battery lasts over an hour now, the speed throttle is more precise, and of course - no burning smell. Definitely more torque. I’m going to be sure to get only brushless tools from now on.
Six minutes and 45 seconds into watching this and subscribing the channel...

I believe my igloo electric cooler s motor is brushless. Its been running almost constantly for the past 3 years and still running strong.
My Ryobi riding lawn mower uses a 48 volt/100 AH brushless motor system. Quiet with more torque than the gas powered rider it replaces.
I use it at a cabin in the middle of nowhere, and charge it with an off-grid solar panel system.

Very well done, from a BLDC drive designer.
Is there any research into improving these motor drivers? I can't think of ways to improve on what we already have...
@@gabedarrett1301 I'm not sure what you're asking. improve in what way?
The development engineers design the driver work the best they can.
With the components we have today and the experience, there isn't much room for improvement.
BRO ONG I LOVE YOUR VIDSSS! Honestly like it’s so detailed and you explain stuff so we’ll!!! Like I don’t normally comment but I had to cuz like it’s satisfying how detailed and well these vids are!!!
My uncle in Florida has a three phase welder and the driving motor is a BLDC motor that's directly connected to a DC generator for welding.
My first time being exposed to brushless motors was a number of years ago when I use to build and fly drones (I need to get back into that hobby again). I also have two bigguns on my all-terrain electric skateboard. Now I'm learning about it because I'm an electrical apprentice. Good stuff!
