Kudos for releasing all this freely, I think you have done a tremendous job,so impressed,maybe one day I will try to make one (well, for may project-a electric sports-car I really need two)
Nice design and eager to see all the details of this motor. This motor can deliver high torque at 2000RPM, this usually good for a small car. It can also be directly connected to shaft with any reducing gears. I like the design of your rotor holder, a fan like shape. For sur this motor will be kept cool. I should implied this in my quadrupole motor.
Direct to the shaft? The torque for this motor at that speed is 120Nm. Assuming a 16" total wheel diameter, the force is approximately 120 / 0,20 = 600N = 60Kgf. On climbs you need more than that. So, gearing like 5 gear ratio will give 300Kgf at 500RPM. So better relation for that. If with direct to shaft you say direct to the differential then that's it, a 5 gear ratio is near the ratio of some differentials.
Very butifull!!! Good luck! Salut! Toata admiratia de la cineva ce isi da seama cita munca este aici! Si eu am niste filmulete ( zic eu interesante ) dar nu se compara ca si complexitate cu ce faci tu ! Sint in Bucuresti si cu siguranta voi avea nevoie pentru proiectele mele de experienta si cunstiintele tale !! Am sa te contactez ! Muuult muult succes ! Chiar meriti!
Such a beautiful design. I am impressed. Your lab setup is also very good. The specs of the motor are also very good. I hope you are able to license a good manufacturing business to make this motor. Sales will be great.
Very impressive knowlege and construction considering limited resources available. There should be an increasing demand for such motors in the future when Electric Vehicle manufacturers finally come to better sense in their designs: Wheel Hub Motors!
Well, that's great! I personally don't need motors this large, but there might be an interesting niche for you - electric powered paragliders. They need a little bit smaller motors, but currently the demand is higher than the supply anyway. Maybe you could look into that direction!
Have you designed a brushless motor for paramotors? I think if the rotor-circumference is large enough the torque would be increased enough to drive the propeller directly. No belt would be needed and that would make the paramotor lighter and simpler.
primul lucru pe care l-am facut dupa ce am defoliat masina de spalat lg astea cu motor brushless a fost sa invart tamburul sa vad ce zice. surpriza produce curent si se aprind toate ledurile ca si cum ai baga-o in priza. Sa echilibrezi bine rotoarele alea ca e nebunie curata ce e acolo. Si sper sa ai un stingator mereu aproape. Bateriile din lada sunt de pe agila ? Ce ai mai facut la ea ca nu ai mai postat nimic.
if you visit or having a holiday in Philippines, maybe we can talk in person. We have the same passion but funding/support here is not good. I'm also having trouble to build my lightweight high torque and high RPM motor.
That's a great looking SRM. But where in the world do you get the stator steel from. I would love to buy laminations, somewhere... anywhere... any ideas anyone? I know its GOES steel for the rotar and stator. The only place I can find is Alibaba and they are only high suppliers. What in the world are the options out there?
With that motor used as a generator thats hooked up to the brushless, what type of increase would you imagine would get back to the battery and increase battery life?
I had some strange thoughts while watching this. I got thinking about how electric motors have to time the electric pulses to the electro magnets in different sequences, and I wondered what you'd need to interrupt the operation of the motor. So I came up with a super-powered person with powers similar to Magneto, except that instead of being such a heavyweight in the power they can exert, they're ability would focus on extreme precision, both in application of power, and sensing electromagnetism. So if they could exert just enough force with their power, to counter the turning of a motor for just an instant, and to be able to choose just the right moment in between ‘strokes’ of the electromagnets, they could kinda of apply a balancing type of strategy, to hold the motor powerless to turn, with little continued effort, by keeping it in-between strokes.
That is really one beautiful 3Ph work of art. You should be proud. I am very envious :-) Your grasp of the brushless power plant is more than respectable! Best in recent memory!
Hi, this project is absolutely amazing ! As these things are quite new to me what would it take, if possible, to downsize this design to make it a replacement for standard NEMA34 or 80/90/110... mm motors we use in CNC applications ? Also could rotation speed be increased to 6000 rpm and above for spindle use ? Thanks in advance for educating me :)
Iulian, I am in the process of building an electric motorcycle. Its for a small bike which has am engine size of 125CC. What type of electric motor would you suggest and is there a way to make a motor for this type of applocation. I would like it to reach speeds up to 65mph with the proper sprocket setup.
You can build the corona electrostatic motor and modify Van De Graaff generator to spin the electrostatic motor very fast with kilovolts of static electricity and then connect electrostatic motor to electric generator to produce AC volts. Your input voltage will be what is powering the DC motor in Van De Graaff generator and output voltage will be AC kilovolts from electric generator. Theory.
Thats really cool Julian, but i always wonder if i can use a rc brushless controller with this kind of motors with just changing the power mosfets, is that possible? best regards
iulian207 thanks for the reply, im new in electric vehicles, i have converted a scooter and a skateboard, now i want to convert mi gokart and here in Argentina is really expensive buying thins outside, that's why I want to modify rc esc. Furthermore can you recommend me some books about brushless motor theory and calculus? Best regards and keep the good work
Salutare Iulian, îmi place foarte mult ceea ce ai creat, super tare. Am făcut și eu câteva experimente pe această temă, dar din păcate mai am multe de învățat. Ce vreau eu este să îți dau un link cu un om din Australia care are câțiva ani de când tot testează, vezi poate puteți lua legătura unul cu celălalt și poate v-a ieși ceva deosebit. O zi bună, așteptăm vești de la voi.
very, very interesting. The motors are good and perfect for electric cars. What is the torque at different RPM? Which controller are you using? Could they be used dirrectly on wheels running at about 1200 RPM? I am very interested in these motors, please, let me know the answers
Salut Iulian. La 2:52 spui ca ai un sistem inchis. Ce ai vrut sa spui cu asta? Este un sistem autosuficient sau doar reusesti sa recuperezi o parte din energia consumata? Oricum, felicitari pentru setup.
Is it possible to make BLDC motor that can have the same or similar rpm and torque output to a car engine ? One that could replace a car engine by just bolting it to the gearbox and with the right input, provide the same or better performance ?
How many poles ? Have you considered sensor-less Field oriented control ? You could control torque and/or rpm. Are you using Surface mounted Permanent magnets or Internal permanent magnets ?
All great. When are you able to make for commercial household application. Must look simple all wrapped up with safety. Plug and Play mode. I am buying. I spent about Aud 2700.00 on power bills per annum.
I have a question if you don't mind? (other than this one :p ) How do you determine what gauge of magnetic wire to use, how thick the coil can maximum be, how close the airgap must be and how many permanent magnets or magnetic coils to use? Like this particular motor for example, was it your goal to make a 35kw motor, or sheer luck (kidding !). I'd like to experiment with making my own electric motors too, one that is powerful enough to use on a small airplane, like a cessna. But I have no idea, what guage of wire to use, how many turns per coil, how much my input voltage must be, whether it's better to use a brushless motor to use without permanent magnets or with permanent magnets, whether my rotor's magnets (or coils) have to be parallel with the rod or slightly twisted...if my rotor must be on in inside of the stator or on the outside or next to eachother.... ? I'm a total newbie, so I have many questions.... any good books, urls or even videos you can recommend where I can learn? Do I use a thick gauge to have high rpm's or high amps output (to use as generator) or do I use thin guage wire with lots of turns, do I only use 2 magnet, 4 or just a little less than the stator like in a stepper motor??? How do I use frequency to determine the speed of the motor instead of voltage or amps, I heard that was the best way to go, but I'd like more than 1 opinion :-) I just don't know where to start and I have very little to work with so I can't afford to make mistakes :(
That's a gorgeous motor, seems to be balanced extremely well.
Respect pentru munca ta si realizari, am trecut pe aici doar sa-ti spun asta. Tine-o tot asa.
Designing electric machinery is not an easy task. Great job, congrats.
Put a 40"-42" prop on it.
I'd love to see that
I'm now super into BLDC motors because of you. Good to see you back. Upload the manufacturing process if you have
how much would t t cost the average working man to purchase one of these from you?,, im speaking in all sincerity about this
$1200-1500 USD from various online places. 35kw is about 50hp, just enough for a Light Sport Plane
Kudos for releasing all this freely, I think you have done a tremendous job,so impressed,maybe one day I will try to make one (well, for may project-a electric sports-car I really need two)
Wow... that’s amazing. Now imagine 4 of these in a car’s hubs! That would be a powerful conversion.
Yellow/green wires are so professional :D
Man, I would love one of these to convert my sidecar motorcycle into a hybrid.

ulisses salvador u
agree check my reply
UR WRONG... the motor is 35kw at maximum power, do you drive your car at full throttle all the time?
no full 35 kw used in part during acceleration the nice part is low power level efficiency of the system.
it is not an engine
Very nice. Have you done efficiency charts?
