Наука
I take 3 things from this video:
1. Having met an awesome engineer that shows how much he likes to talk and share about interesting topics! Thanks for sharing!
2. A lot more knowledge about these motors and a renewed desire of building one just because it's cool
3. A phrase "magical hu-ha" that I will most definitely be using in my meetings at work haha
Wow, thanks! magical hu-ha is magical
I just worked with a guy like you. Very smart and fast with explanations, made my brain shift gears and stimulates the neurons.
Hopefully that is a good thing
This was exactly what I was looking for. Thank you for your holistic breakdown.
Happy to help
It was great to hear the cons of this motor. Most of the information available comes from people trying to sell axial-flux motors, who only tell you the pros.
Nothing is perfect only right tool for the right job
I've been thinking a lot about using this on bicycles. We could laminate the coils into the carbon composite frame and sandwich the rim between the two stators. The rim acts as the rotor. I wonder whether we could reach the required specifications of 500-800 rpm on a 29" wheel and up to 150 Nm of torque and still be lighter than a typical mechanical drivetrain? I've seen power densities for axial flux motors ranging from 2 kW/kg to 15 kW/kg. Considering that a pro cyclist puts out up to 800 W (not considering time trialists), that would suggest a range of 50 g to 400 g. Which would be a lot lighter than a Shimano XTR groupset at around 1,500 g. It's probably not realistic, because of overhead for structural material, but still, it shows that there is a lot of possible headroom.
possible YES cheap NO
Good eye opener on axial motors. good presentation
Glad you liked it!
Excellent introduction to axial motors and I enjoyed your casual but succinct presentation style. Keep it up!
Thanks, will do!
Very useful information for my paper and some experiments. I find the inertia factor the most appealing about this. Thank you for the explanations!
Glad it was helpful!
I love how you pair the theory with the real world. This is something that 99% of educators are missing. You clearly have a firm knowledge of both so anything you say that might cause question quickly gets solidified with a real world example. Excellent.
I am glad you liked it
Greeting from New Zealand! Very informative Sir, I greatly appreciate your efforts!
Many thanks!
Awesome explanation! Thank you.
Glad it was helpful!
i;ve seen a couple of videos about axial but im glad you keep repeating about geometry. in real world or applications, the advantages of axial vs radial is even, only the shape of the motor is different. so if one could reuse or take advantage of the shape of axial motors, like using it inside the wheels of vehicles, packaging is improved like more interior space for cars.
good point also on trucks, since they already have huge diameter wheels where axial will work even better and does not need high RPM.
Glad you liked it
Thank you for your excellent primer on this topic.
Glad it was helpful!
very good video ... but honestly - you have to slow down a bit ... english isnt my first language but im working around birmingham/uk for a couple years now and also with a lot of people of asian descent, still i needed to concentrate quite hard because you are talking with the speed of lightning :)
thumbs up!
Thanks but my camera has recording limit so I Cant do much about my talking speed I will try to buy a better camera soon
@@s2tenglish I'm British and used to live in Bradford (!!) so am more used to an Indian/Pakistani accent than many. I too had problems understanding some of what you were saying.
If your camera time is limited the BEST thing to do is record in sections then just concatenate the clips. Plenty of free tools around to help you.
Great explanations though, not just about the base technology but also to describe the "so what?" scenarios about where, when and how it would be of benefit and when NOT.
Thank you. Very helpful.
Glad it was helpful!
Great lecture but just need to slow it a tiny bit so us lesser mortals can keep up
Sorry U can slow down the video to your liking as I am dealing with camera recording limit
Great explanation! Thank you!
Glad it was helpful!
Finally a video that helped me understand the difference between radial and axial motors. Thank you. Just liked and subscribed.
Happy to help
Excellent presentation thank you
Happy to help
Amazing video as always ! Your way of speaking is extra entertaining and insightful. Please keep the good work.
Thanks
Thank you very much
This was very informative
Enjoy
Very well explained. You nailed that puppy! Thanks
Glad it was helpful!
About your overheating/cooling issue... I'd use compressed Helium gas, blowing directly between the coils & PMs. It's non-reactive, so it's not gonna oxidize your copper coils. I'm thinking specifically for electric planes. Nice video.
Extra stuff in plane is no go & pressure tanks can go boom & extra consumables is not a good thing to add
BRILLIANT VIDEO..A MAN WHO ACTUALLY KNOW HOW TO STAY ON TOPIC..GREAT EXPLANATION..MAYBE U CAN SHOW US MACHINES TO MANUFACTURE AXIAL FLUX MOTORS..DETAILED..THANKS..GREAT MAN TALKING AND EXPLAINING..WE LOVE MORE DETAIL TOO..
Maybe one day
Great video thank you
🤜🌟🤛
I am Glad You liked it
Loved your video!
Glad you enjoyed it!
Very good video thanks!
I am glad u liked it
This is amazing.
Enjoy
Loved the video. You are also rather funny! :D Learnt a lot. Thanks.
Glad you enjoyed it!
This is great information, thanks for sharing the knowledge. Motor and/or Alternator, Axial Flux efficiency rocks!👍
I am glad you liked it
Nice presentation. I really like ur interest and knowledge. It is good to see that you enjoy your work.
thanks & I do my best
Thank you for this great insight about axial motors. As a non native english speaker, it's quite hard to follow you because you speak quickly, subtitles would be amazing.
Keep doing this, I love this subject.
Cool, thanks
@@s2tenglish you can slow him down. click gear icon playback speed and .75. I have to bump most up to 1.25 or 1.5 but your speed is great for me.
I didn't think about slowing down the audio. I think some of the magic would have been lost.
Don't feel bad. I'm a native English speaker and have a hard time keeping up. Guy talks super fast.
This was great, you explained everything and you are very funny. You're expressions, big ass motor, and this puppy... Cracked me up. Thank you
enjoy
Amazing explaination! Keep it up.
Thanks, will do!
Good stuff, thank you very much :)
Enjoy
This seems perfect for in-wheel hub motors! Distributing the propulsion into 4 wheels should give further advantages from in power density and for unsprung weight. Besides better traction and 4x4 drive.
For smaller cars maybe just passively air cooled?
I also don't understand why these are harder to mass manufacture than radial flux motors.
Thanks for the video :)
mass manufacture is tooling industry if there is a demand for it then even complex things can be made easily without it well good luck
I've been thinking about this A wire hs to get to it though right? Where cod that be placed?
@@aicram62 The stator would be fixed to the axle so cable would run like a brake line
Thanks for the video. You are fast, consequent difficulty to follow (mech.engr 71 years). forwarded the video to the eng. students whom I guide sometimes.
Thanks
I know about motors like this back in 81 . Also you can make crazy generators this way .
yep most DIY wind generator are axial in nature
Thank you for the most succinct explanation of the axial motor technology 👏👍🙏
Glad it was helpful!
Had to subscribe because your intelligence is way above average. Thanks for explaining the difference between axial and radial flux.
I tried to design a BLDC driver by studying my motor's trapezoid wave forms using a dual trace oscilloscope. I was unsuccessful. I could do it easily with a four trace scope but I'm not under a deadline. I'll figure something out.
I think electric airline flights would be possible with smaller regional airports using planes that have swap-able battery modules.
My thing is electric paramotors. You could keep an electric paramotor in your apartment. Use gas only if you want to do cross-country flights where you need to gas up.
I am glad you liked my video
Very well done explanation
Glad you liked it
Awesome! TY!
Our pleasure!
High density information in a small video. ❤keep it up 👍
Glad you liked it
First time watching you and I already love you. Great video puppy
You are so kind
Great video!
I have a question on the robotics application part. Since this axial form will generate more torque when using same amount of material, wouldn't its overall performance be better than the radial ones? I understand that it will have greater inertia, but to get same amount of torque, radial motors also need to reach the same, if not bigger, motor radius?
yes radius will make it tough to include inside of robotics It can be done and if u look around U may find that some already does there is also the issue of supply
When you have a larger diameter wheel, it has more inertia for the same mass. So while an axial can be less mass, the larger diameter counteracts this.
Perhaps these type of motors could potentially be useful in locomotives? Or railway applications in general? Anyway , thank you very much for the clear and concise explanation.🙏👏
not really its best for super high power to weight ratio like HYPER CARS & EV aricraft
Great video. I am looking at making a hydro generator out of something like this, but have a lot to learn. Off to see if you have any videos on PMGs!
Cool, thanks
Have you started your hydro generator project? I've been working on building a portable hydro generator to charge powerbanks for backpacking and I've been having terrible luck getting sufficient power outputs after trying DC motors, a brushed AC motor, and a Nema 17 stepper motor as generators.
I think an AC generator motor with a full bridge rectifier seems to be the way to go. Perhaps I'll have to resort to building an axial flux version.
Excellent, common sense presentation!
glad you liked it
Just wanted to say that I really enjoyed this video but had never tried the "tap the dislike button twice" thing and accidentally submitted bad feedback. So please ignore it! I actually loved this video. I'm so sorry!
Enjoy and don't worry about it
5:51 I lost it 😂. Loved the video.
glad You liked it
What's stalling the mass production of axial designed motors? I'm guessing it must be in the windings of the copper wires. They haven't figured out how to mass automate the copper windings and have it all connected properly. As for other parts, they seem fairly straight forward to mass produce. The cooling I'm a bit confused how it could be easier to design and make the cavity imbedded into the stators throughout. I also suspect that any uneven heating will cause the rotor to slightly warp which will cause collision due to the tighter air gap, it'll start to sound like when your wheel disc brakes wear down to the metal.
its the stator not the winding as it need to be made up of layers geometry just does not work . In normal u just stamp the sheets and stack here GOD HELP YOU
Wow so informative
Glad you think so!
This was such a great video you need more views, subscribed
Thanks for saying that
I take 3 things from this video:
1. watch on half speed.
2. As a native english speaker, I feel so slow when I talk and listen now.
3. This is ADHD in real-time.
What the HECK 🤣🤣
Would there be any benefit to put these in linear actuators? Like "roll out" the stator along the length of the actuator and have a ton of small permanent magnets along the shaft. I would think shaft inertia would not be that big of a deal because it would be replacing things such as hydraulic cylinders and pneumatic cylinders.
linear is its own topology and its closer to radial flux lines
wonderful man
Many many thanks
thank you so much. bw could you make a detailed video about quark motor
I can help you to understand frequency component High Frequency AC Explained ruclips.net/video/kD9Fo_GBEbc/видео.html how we get high power density
well done
Thanks
Thank you very much sir for your wonderful and information dense video. You deserved a like and a subscription. Please keep up the good work
I will do my best
New subscriber here! Thank you for very comprehensive videos, sir. Can you please explain it further, what would happen if this axial flux motor had 1 rotor, but the fixed magnets plates are above and below the stator, meaning there are 2 plates of magnets?
yes it quite common to have coils in middle and maganet on both end but its wastefull as maganet is more expencive so coils are put on both ends
You should work in sales I did not understand how it works but I already wanna buy it
LOL nice 😄
A word of advice. You have a strong accent, and with you speaking soo fast,I was only able to understand about 1/6 of what you were saying.
You can slow down the video to your liking . I am dealing with camrea recording limit
Very good content. One sugestion to speaker. You need to slow down when you speak, or slow down the video 0.75%.
This is my talking speed some find it fast some finally a video that doesn't need to speed up that is why yt started giving playback speed control on video
A little bit fast-paced but it did make me pay attention
happy to help
How well does it work as a generator?
if there are a set of windings on each side of the rotor can they be wired in parallel or series for double output?
Or do they have to stay separate in 2 phase?
DIY wind Turbine community uses is a generator and yes it does goes to 3 phase
Can you make a video on design calculation of 2 hp axial motor sir It will help to my project
Sorry I can't help you
Hi there. Greate video. Subscribed!
Thanks for the sub!
Nice video
Thanks
It always stuck me that the Tesla Turbine was an excellent model for forced cooling axial motors. I think that the tangential air flow in the turbine would mean that you get more heat transfer from the stator(s) to air.
Humm
👍
Liquid cooling vs motor that is air cooled
So you have a smaller motor that can handle more power - but you now you have higher complexity and need more space and extra weight for cooling system. Is the trade off worth it it in the end for a smaller motor. Or just go for a bigger air cooled motor that can hand same power.
Cheers
bigger rotating mass is not desirable in aircraft and U need cooling subsystem anyway so add bit more capacity
Man this dud its hilarious as fuck far and as the information given was exactly what I was looking for. You got a Sub for this one!!! 👍👍👍💯💯💯
I am glad u enjoyed it that much and thank you
"This will make f1 motor look like bitch race" lol subscribed.
ENJOY
Your magnetic knowledge density and the familiar use of english language are excellent, subscribed.
On point immediately, then I checked out your channel, A TEACHER YOU ARE.
1 question "axial-flux makes F1 like bitch ????". You need not change your delivery, others need to adapt to speedy One World english. Your efforts are noble, Thank You kindly.
I think he said "bitch, please" (5:50) which in American English would mean "yeah, right", "as if", or "pfft" (sarcasm noises). I think he's saying that the F1 engine would be laughably outclassed by axial flux. I can't tell you what part of speech it is because it's a humorous usage, not formal grammar.
F1 engine's have one of the best power to weigh ratio and axial flux motor can beat it
excellente video. do you know where can i by a printed axial motor?.200/300 watt and 30/40 volt but not 300$. grazie 1000
I don't know & I don't think they are mass production units
Magical hu ha technology
😊😊
what kind of power density and size can you get for a bicycle using Axial Flux motor ?
Chinese companies are very popular for e bike motors. Like bafang . I wonder is it possible to get a more powerful motor, and get the same size, or smaller than BBSHD motor produced by bafang ?
axial motor would be great to e bikes as they utilize the wheel diameter for proper performance but as I said in the video it can be done but someone has to spend R&D to design it and mass production of it is another issue
He disserve more subscribers then what he have now.
Thanks
So what if the coils were made the same way a processor is made?? Extra thin with longer windings... printed
people are working on it
This is fantastic and your English is great 👍 so my understanding of this is the axial flux motor is more efficient because of the high inertia of the rotor? I'm planning to build a wind turbine and I've concluded axial flux is the right motor for the job :)
turbine & motor what ? now if you are talking about generator yes people do make axial flux for DIY wind its very popular
@@s2tenglish Yeah a wind turbine with axial generator, I think I'm gonna made it myself too 😁 I'm just doing my research now (I've been at it for 4 hours so far 😂) someone I follow on here Kris Harbour natural building he made one and regularly see's 300 - 500w in 10 - 25mph winds, it seems mad not to have this when I buy some land and very similar to Kris I'll be building a self sustainable farm 500w for free is not to be sniffed at! :)
@@s2tenglish a question for you: the magnets are on the outside only, if they had two rings one closer to the centre and one closer to the outside would that be more or less efficient?
I don't understand ? generally u want to cover whole of the coil meaning whole of magnets flux should cross the coil
@@s2tenglishyou have windings and magnets on the outer I
Edge, what would happen if you put another set of windings and magnets towards the centre as well?
GOOD CLEAR AND EASY TO UNDERSTAND GOOD JOB. THANKS. PLEASE TRY TO SPEAK SLOWER.👍👍👍👍👍
Thanks & I will do my best
Thanks mate! Awesome presentation. Subbed!
Thanks for the sub!
I love it need to talk WOW !
WOW
Thanks for the detailed lecture!
What a difference to the disco light show on a stage and some saying (con-ing) about their new motor, that was already described in a book in my shelf dated 1901 (no typo, 120y ago).
This motor here is looking like a linear electric motor wound to a disc. More „lever“, so more torque on lower rpm -> direct wheel drive, no gearbox.
The fanboys are currently freaking out because Mercedes Benz just bought a company building these motors. Elon fans try to tell you everything you need to not know on why such a motor will not work in cars at all. Same as they praised the „new“ reluctance motor at least 120yrs old.
well at this point in time Hype sells more than facts
Oh, Man. Will you run for President? I love your video. Thanks for the explanation which I can understand. F-1, B i t c h, please? Is that what you said? I hope so. Very funny!
Well thanks
i like the speed usually 1.5x is not fast to listen in short time
LOL most people ask me to slow down
Very clear, no wasted time, I like this faster form of presentation.
Thanks
I love when presenters are professional and enthusiastic, but still drop terms like "Huge ass motors" 😂 I had to rewind to see if I heard that correctly
Having fun is important
I want to build a DC motor with 20Nm constant torque. 48-72V
is that hard to do or rather "easy" with this technology?
if you have freedom of large diameter go for axial flux
@@s2tenglish thanks!!
I can go to 145mm or even 180mm diameter (but need a 83mm hollow shaft) looks like there's quite some unused space in the center??
@@jpjay1584 ok now I thnk u can only do it with Axial Flux & look into PCB motor for easy of manafuctring
@@s2tenglish can a PCB handle 20Nm?
how to calculate an Axial Flux motor (non PCB) 450RPM and 20Nm constant torque.
how many poles is ok? the more the better for torque, right?

Hello, could you enable the subtitles and if possible in Spanish? Thank you
sorry I don't know Spanish so I wont be able to verify it
Isnt this how a VHS player head spins?
not really its was not widely used
Free energy design in profile pic.
Design to make pancake generator.
Then make it
why axial motors are not in bikes?
cost as its new tech and not really mass produced
👍👍👍👍🤜🤛💥💥
GG
The original could have had the paired .magnets closer
what ??
most submarines use axial
will army does not share that info so I cant know that but it does make sense
Kinetic battery
not really that useful
This is a good video but you need to slow down your talking so fast your hard to understand thanks
Sorry about that U can slow down the video to your liking I am dealing with camera recording limit
