Horizon as a company has been a pleasure to deal with. Bought Axial Jeep JLU in late Nov 2020 and it had a faulty servo on the DIG function. I live in Canada and Horizon warranty the servo on my word telling them. Shipped prepaid and arrived in less than two weeks. This video is very helpful when being bombarded with what's available to buy for aftermarket motors. So Thanks for making these videos.
I felt the need to put this out there, the reason for 3 wires vs 2 wires on BL vs B is more so due to the commutation. A brushless esc needs to have an electronic commutator inside rather than the physical of the brushed.
It is specific to each motor honestly. Most high-performance brushed motors aren't being produced any longer as most of these manufacturers have moved to brushless technology.
I understand what you are saying. With any "sealed endbell" motor there is the opportunity to "pop" the endbell off by applying enough pressure to the tabs to make them spread. This motor is not designed to have the timing adjusted once it has been assembled.
I think a better way to explain brushless vs brushed is that a brushed motor uses a mechanical switch to change polarity and a brushless motor uses a computer and solid state electronics to do it. It's like mechanical fuel injection vs electronic fuel injection, the real benefit comes from being able to adjust timings without physical changes to the motor and having less resistance from mechanical parts.
Brushless motors do NOT run on AC, they are DC that is pulsed to different sets of coils. They basically replace the commutator. The basics are the same, Electricity runs through the coil's creating a magnetic field and repel or attract to the permanent magnet that is part of the rotor. The coils are labeled A,B,C and the electricity gets flowed from A-B, then B-C, then C-A and repeat in a circle . Sensored brushless motors have Hall Effect sensors (usually 3) that tell the Electronic speed controller (esc) what the orientation of the rotor is currently in so the ESC knows which set of coils to apply current to.
if you listened he said they basically work on AC, which is true. even though it is technically DC, a waveform that is basically a modified sine wave with a bunch of PWM is what an ESC sends a brushless motor.
Kv-A rating of performance for brushless motors. While Kv ratings are occasionally applied to sensored motors, sensorless brushless motors are almost always rated by Kv. The higher the Kv rating of a motor the faster it will be. Kv refers to the number of RPM a motor will produce for each volt of power input to it For example a 1,000Kv motor would produce roughly 7,400 RPM at 7.4 volts.
All depends on if you want to go brushed or brushless. I've heard very good things about systems from Novak and Tekin in both brushed and brushless. The Timbuk2 from Novak is quite popular for an ESC along with their 21.5T or 18.5T motors.
Let us make this even more clear: A brushed motor runs the current though the armature making it electromagnetic that interacts with the permanent magnets in the shell of the motor. A brushless motor has a rotor with permanent magnets and runs the current in the shell making it electromagnetic that interacts with the rotor.
Depends on the size of the motor quite honestly. There are brushless motors for 1/5-scale vehicles that will blow away the power of those for 1/10-scales. Generally the fastest I've seen for 1/10-scale are the 2-4T motors. Crazy fast!
OUTSTANDING video! Very informative. I fly quads and am moving up to brushless motors so even tho you were talking about RC vehicles, it still translated well into how it would apply to quad multi-rotors. Many thanks for a great video.
Your knowledge on this topic is awesome. Really appreciate you taking the late nights opening and playing with different motors. Takes a lot of patience, and a very cool wife if u know what I mean. I have to sneak my RC time in. And everyone knows that once u sit down and Start dissecting for hours without noticing
Anything besides a 27T brushed motor is considered "Modified". It refers to the racing class the motor is legal to race in. A 13-double is going to push the limits on that ESC but you should be ok.
Almost all electric motors are ac (stepper motors excluded) - in other words the current must somehow be switched in direction every half cycle if dc is applied. In the so-called dc motor this is achieved by the commutator, which reverses the current flow. A brushed ac supplied motor uses slip rings to get the current to the armature. Great channel, thanks
No argument there, however in terms of RC getting a working and reliable brushless system was a pretty big breakthrough and advancement. You can go back to the days after Nikola Tesla and see the groundwork laid there.
That was an excellent video, it really cleared up the whole Brushless motor technology for me.... Now, to learn about lithium batteries and esc for brushless. This is what I get for 3 years out of the hobby haha
Very informative video for someone like myself who just decided a few days ago to buy a car after about 1 day of research. I'm a beginner and I want my son to enjoy it with me but dont want a car going too fast but I also want to know how to upgrade when time comes.
motors are a fun hobby in themselves. the sealed 540 motors can be safely opened and if you know what you're doing you can easily change the windings with bigger gauge laminated wire without soldering and have some cheap fun. if you can find small bearings with the right I.D/O.D diameters then you fit them on the front and end race. got 15t and 10t motors in sealed cans with a double 10t in the making all running off a tekin G9. mabuchi and johnson motors can easily be found next to nothing for rebuild or spare bushes. have fun :)
Yes and no. A 550 Motor is a slightly longer version of the 540 motor, capable of delivering more torque and power without suffering from power loss. 550 motors tend to be less susceptible to damage from heat, overgearing or other similar issues. Now there are 540 motors that can be used in 4WD SCTs that have the best of both worlds, less weight and exceptional torque.
Awesome vid! Helped me understand electric motors a bit more. I'm a nitro guy, but i'm willing to try to understand the other side of rc. Lol, good job sir!
The fastest that we're going to have is the Formula Pro BB Modified 12T,Double by Team Orion USA (ORI22035). Unfortunately just about all high-performance motor developers have abandoned brushed technology for brushless.
Very good video. Very informative. I learned alot since I took my team Losi buggy and my Traxus truck out of the closet after years of storage. I have watched alot of your videos and learned what's in and what's out. Thank You.
That is a very informative and nicely explained video. I attempted to do a video not to dissimilar to this a little while back and while I did have a lot of the basic right I wasnt able to go nearly as in depth as you guys did here mostly because I have very little experience with brushed motors.
Thank you, this video was very helpful in knowing the difference between brush and brushless motors. Plus I couldn't remember if more or less turns on a brush motor made it faster or slower. Very good info for RC car motors.
What is actually happening is a voltage change by reducing turns. Makes sense to go this route rather than add more batteries which would weight down the R/C car more to get more speed and power.
maybe I missed it but I didn't see anything in this video about using brushed motors for RC crawling. Censored brushless motors do have use in crawling but top competitors still use brushed for lower end torque and slow speed control.
Its not better as much as its just different. A smaller pinion will give you less top speed but better acceleration. A bigger pinion will give you more top speed but cost you acceleration. For running on a track going to a smaller pinion could make you "faster" as the motor may not have to work as hard to clear obstacles or to get out of a corner. For just running in a driveway, open lot or parking lot a bigger pinion will yield higher top speeds.
Whoever decided to introduce "brushed" motors to the RC industry was a genius. Being that "brushless" motors have been around for years and don't require any maintenance, they chose brushed to be able to sell parts and perform repairs. The greatest difference between these two types wasn't mentioned in the video. A brushed motor spins the electronic circuit inside a permanent magnet, whereas a brushless one spins a permanent magnet inside an electronic circuit, improving the efficiency tremendously. PEACE
Actually brushed motors was the preferred option because they were the cheapest option for a long time because of the cost of bldc controls. Even now that bldc controller cost have come down brushed motors are still cheaper. But now with the reduced cist of BLDC controlers. The maintenance-less advantage of bldc motors brings more "value" that makes up for the additional cost. In other words, it wasn't a marketing gimmick to sell maintenance. Rather, the choices were/are comsumer market forces, cost, and application need driven.
Anotjer and maybe better description then you gave is that brushed dc motors have perminate magnets in their stator, and their rotors have armatures with winding that take in DC currents through the brushes that contact the commutater that when rotating switches currents in the windings. BLDC motors have perminate magnets in their rotor and take DC current to the motor's controller that in turn electrically switches currents in field windings.
In dynamite 20t shown in 2:11 same as saturn 20t we can change timming settings by turning the endbell. But there are only thre position of that setting, you can see it above negative lead connection to the motor 1:02.
I've built my own bldc motor and am trying to figure out what bldc speed controller would be appropriate. First thing, the motor is axial flux. The rotor has 12 poles (6 pole pairs). The stator has three coils wound with 16 gauge wire. The winding are a falharbor type winding with 4 turns (roughly 76 inches of wire in total per coil) adapted to an axial flux design. The stator has a slotless iron backing made from coiled steel banding to reduce the magnetic reluctance. Most radial flux bldc designs use 3 coils and two poles. I wonder if 12 pole 4 falharbor serpentine like turns would be roughly equlivent to 24 turns or something else on some of the more standard motors. I tried to run it on a cheap bldc controller. The bldc controllers lowest setting drew .6 amp from a 13.4v lead acid battery. That's about 8 watts. At that lowest setting the controller supplied 1.49vac, and if we assumed 100% efficent transfer of 8 watts 100% meant the coils were pulling 5.37 amps. When the motor was turned by a by a drill at 211 rpms, it generated 0.126vac. During testing the cheap chinese controller blew a couple mosfets. But ill try to answer any other questions. I might redo the stator with 5 turns on each coil. But there is not much hope for more turns..
This Is why I like nitro, it is simpler. I think tuning and caring for an engine is much easier, plus I always damage any electric vehicles I touch sooner or later...
Thank you very much for the info!!! Would a 10T ESC been better for this 13-double? I wouldn't want the ESC to fry..... BTW, I absolutely love your videos!
Tried a few of the Dynamite 540 15 turn motors. They don't like being run on 8.4 volts. They don't run hot but the commutator burns up and turns blue. Meanwhile the Traxxas Stinger runs twice as hot (stingers always run hot) but they don't burn up on 8.4 volts. I think Dynamite should go with Johnson or Mabuchi instead of whatever off brand they're using.
thank you for your vide.,it is very informative.I use to race rc 10s with my dad back in the mid 80s I am thinking of getting back into the game.and thgis video is very helpful as far as info on dif motors..thank you again.very nice video.keep up the good work.
I have used a giant brush less motor for giant scale rc planes One of them would cut out at high throttle and let out a terrible squeal when it did But throttle back and it reset and goes again. There was no over draw in amps and was using the correct voltage The lipos can deliver more then twice what the amp meter showed as being used. My question for you is How important is switching frequency and how likely is that to have been the cause of this?
You dont need to open the endbell. Just try to turn it. The tabs just prevent the endbell to come off but you can easy turn it. That is difrent design than mabuchi or johnson motor.
this info is our work together with FORD ENGINE. if you change the crank shaft to diamond witch you can melt at super high octane like rocket fuel but it wont melt at 89 octane so if you build a mold for a diamond crank shaft or machine the diamond with laser to make the crank shaft that you just gave me as an idea witch will not tiwist the shaft and throw it off ballance then you don't need to add oil to the motor for the shaft won't twist with out oil now if you want precise mesurement for the piston borring use a 5/12 circomfrance angle around the piston
Thanks for the info! I needed to know how fast in terms of mph speed w 20 turn and under to say a 10 turn brushed motor and 3400kv -7500kv bless in turns of mph? For example getting 40mph you’d need or equals to a 15turn motor etc... thanks!
What kind of motor do you think would be the best for the Losi night crawler? I was trying to give it a little more speed but also try to make it keep its torque. so if you can could you please suggest a type of motor or a certain turn for it? Thanks for the help.

He got me pump about building my brushless motor in my 1/10 scale 💪🏿🔥🔥🔥👌🏿💯
It would be better, yes. It just gives you a larger margin for error in case something happens.
Thanks for the compliment!
I love these videos with this guy. 😎 i always think of him as an RC professor. Hes taught me ALOT as a young RC wannabe.
I'm a little late to see this comment but thank you for the kind words - Gary
How does one get that kind of shine on ones head? Love it.
thanks for the help. I am running a brushed system now and was wondering what i should use.
Thanks for the great instructional intro to these motors !
Great work and easily understood

Thanks again.
Thanks I'm a big fan! Thanks for the help. Your one of the best rc channels!!!!!
Charlie is one of the best!
Great video, it really helped me understand how the brushless systems work. Thumbs up.
27T Stock motors were not allowed to have bearings per ROAR Rules.

Thanks bro, I needed this!
good video for breaking down the basics
Hi um Anthony I have 3 brushless rc traxxas 110 th scale vehicles myself this video is very enteresting too 👀 watch. I learned alot from this.
In very simplistic terms, yes.
Awesome review... Thanks a bunch!
Thanks for an excellent explanation ! This is what i was looking for.Thanks again.
Reducing the timing will reduce the RPM and increase the torque of the motor
Get closer look in to the endbell above negative lead. There is teeth on the can and three holes in the plastic below that teeth.
What is actually happening is a voltage change by reducing turns. Makes sense to go this route rather than add more batteries which would weight down the R/C car more to get more speed and power.
maybe I missed it but I didn't see anything in this video about using brushed motors for RC crawling. Censored brushless motors do have use in crawling but top competitors still use brushed for lower end torque and slow speed control.

For just running in a driveway, open lot or parking lot a bigger pinion will yield higher top speeds.

Thanks. Too informative. This video should have been 10 minutes long.
There really isn't unless you open it up and unwind the armature.

THANK YOU for video.. now I know what type of motor I need to replace for my car..
Thank you very much for the info!!!
Would a 10T ESC been better for this 13-double?
I wouldn't want the ESC to fry.....
BTW, I absolutely love your videos!

Kick ass vid, now that I know the motors inside out, am I still struggling to identify what the 540 and 550 refer to.
Thanks for the crash course
This was so helpful . Thank you !!
Thank you Sir, Good presentation, Now I know what I didn't know before.
Thank you so very much for the tutorial . It helped a lot.
Very good video, very informative, thankyou for sharing!
I have used a giant brush less motor for giant scale rc planes One of them would cut out at high throttle and let out a terrible squeal when it did But throttle back and it reset and goes again. There was no over draw in amps and was using the correct voltage The lipos can deliver more then twice what the amp meter showed as being used.

Fantastic tutorial. Thanks
Cool thanks! also I bought a new summit from you guys! I also got a dhk shogun 1/8 scale I'm going to rebuild myself ! thanks guy
You dont need to open the endbell. Just try to turn it. The tabs just prevent the endbell to come off but you can easy turn it. That is difrent design than mabuchi or johnson motor.
Helped me for my motor needs
Thanks for the info! This is great.
Great explanation, thanks!
Thanks for the great vid! Learnt heaps!!!
Great video! Thank you so much!
this info is our work together with FORD ENGINE. if you change the crank shaft to diamond witch you can melt at super high octane like rocket fuel but it wont melt at 89 octane so if you build a mold for a diamond crank shaft or machine the diamond with laser to make the crank shaft that you just gave me as an idea witch will not tiwist the shaft and throw it off ballance then you don't need to add oil to the motor for the shaft won't twist with out oil now if you want precise mesurement for the piston borring use a 5/12 circomfrance angle around the piston
Thanks for the info! I needed to know how fast in terms of mph speed w 20 turn and under to say a 10 turn brushed motor and 3400kv -7500kv bless in turns of mph? For example getting 40mph you’d need or equals to a 15turn motor etc... thanks!
You need the gear ratio to calculate the speed.
What are some of the fastest motors out there? I'm new to this and just trying to learn your video helped me a lot
Thanks for the explanation, very clear!!!
i learnt alot more from this
Top video very useful
Holmes Hobby Brushed Motors are the best imo. they have Bearings in them. most brushed motors just have a brass bushing.
What kind of motor do you think would be the best for the Losi night crawler? I was trying to give it a little more speed but also try to make it keep its torque. so if you can could you please suggest a type of motor or a certain turn for it? Thanks for the help.
Do lower turn motors have better speed but less torque or something? Why would you opt for a higher turn motor? Sorry I'm way new to this stuff
