Beautiful work.
Thank you so much for the website link of the winding calculations! Wow! Never knew they had one. Great idea!!
Wow! A skilled engineer sharing knowledge. Thank you!
I have been rewinding Brushless motors for sometimes now. I have to admit yours is one of the Finest I have seen. This thing can power a small plane, just by looking at it. GOOD LUCK. I do hope that you will share some more Pictures/Movies. GOOD LUCK :)
Would you please help.
I am not an that expereinced in electric motor but I wounder how good or how bad would be my design. I designed a BLDC motor and that seems to be perfectly good enough on paper. Would you please try it in a simulator or tell me how to make it be better even from your knowledge. I would ask you to advice me to use a specific stimulator or such but unfourtuantly, I have a REALLY BAD PC.

WOW great work man! Congratulations
WOW 👏👏👏👏👏
this is amazing. U could build ur own emergency generators, electric bikes , etc with this.
beautiful work. Thank you for showing your wonderful motor. That represents a lot of work and money to make.
Julian you made a fantastic job there, congratulations.
This is absolutely amazing! Thanks for sharing.
This is awesome! thank you for uploading this.
Holy moly this is amazing, thank you for sharing all your hard work! Even at 45KW this would blow small car gearboxes :)
Congratulations on such impeccable work.

I like the blast shield! Ive only done a couple projects that made me hide behind a wall, you know its serious when...
On 2:18, wooden particle board. To protect the legs.
nu cred ca tine PAL-ul ala la niste shrapnel la 2600rpm
Now try adding a spinning lawnmower blade to the thing and you'd have a battlebot!
man, this is awesome. you are the engineer!!!
You'v done some great work, thanks for sharing!
AMAZING WORK! Very well done!
Wow, Smart man. 45Kw is big power. Impressive that you built it alone.
Good for powering small EVs too.
Excellent job!! Congratulations Iulian
awesome work iulian God Bless !
Mandru ca sunt roman cu oameni ca tine :)
Well this is excellent! thank you for showing. pierre from New Mexico
Felicitari !! Superba treaba, salutari din Londra
Good relief that you have made it to work and not have to discover that nothing worked at the end. Great careful job man!
Beautiful work!
very cool project , gives me idea's
Fantastic job! Very professional, thanks for sharing.
Fantastic work mate, from the UK
Wow this is freaking awesome dude!!! Subscribed and checking out your other videos... ohhh yeaaahhh... so much POWEEEEEERRR
Remarkable. Well done.
Un potențial de piață enorm.
so many nice videos for a change thankyou for the over the top unity on this adventure that is in my soul ary nice
very cool design, big respect !
That cooling system is awesome!
Julian man, you’re a genius. Hey, what happend with the 3D modeling video? This is aamzing
i like it, serious fine work you done, bravo!
Nice job!!! Congratulations!!!
Great work! I`m really impressed!
Tare, bravo!
Bravo, esti tare de tot!
Very nice, its an inspiration to me, im thinking of making my final project at electrical engineering course with something about the brushless motor, keep engineering!
Wow! Amazing work
Quite an impressive piece of engineering, sir
amazing work!
This is fascinating.
Amazing work!!!
Very impressive work!
my god man, you are a genius
Julian that was truly an impressive "diy" (i think your a lil above the diy moniker!) motor you created. id love to see its end application. good video. teach us!:)
Great work!
Thank you so much.
Beautiful work. A bit bigger than was looking for. It needs to go on my Skateboard.
Luxo amigo!!!
+Dantes Alves de Santana Queria poder fazer isso aqui!
+Elvis Silva N é difícil n amigo estou fazendo um gerador assim o principio é bem parecido.
Estava com ideia de usar os ferros do motor de maquina direct drive
Sou seu fã Dantes !
Obrigado amigo!!!
Awesome work
Nicely done. I would love to build one myself
Nice hardware set up, test place and video montage TERIBLE
Great work.
You are a serious engineer! I am just a electronic technician with years of experience I say you have a great design.
its shit. you cant feed 1 khz waves to steel sheets
1 khz is nothing, and anyway I don't know what you mean by applying waves to steel sheets, you must be talking about applying the magnetic field to the steel sheets, but even that is a standard practice in electric motor engineering.
Mark Osborn steel sheets struggle with 60 hz and this dude here puts them at khz range. that is why most of the motors for commercial use are long and have smaller diameter. the more sections you have-the higher the frequency needed for the rpm. this means that this is torque optimized motor, but its very bulky for the torque it can deliver. also long axis small diameter rotors are better than this short thick one, because of the lower inertia- a big problem with EMs
Are you an engineer or just an arm chair technition?
Mark Osborn im far from professional engineer as you can tell, but i know a lot of stuff and go into detail on everything
im 16. i know almost nothing about brushless DC. i have a test tommorow. what am i doing here. I know exactly what im doing here. they dont teach this stuff at school so here i am trying to reinvent the whole thing. This is probably the coolest custom motor ive seen in a while but i need to study
I disagree, I learned all about motors and magnets in my class this year
You can learn this stuff in electro technical school.
the first class about magnetic induction, it was on the 6 year of school....
There is no such thing as a brushless DC motor... its a 3-phase AC motor running off a VFD, which has a DC power source...
There is no such thing as a motor... its a rotary system of magnetic fields and coils setup such that the pole pairs continuouse moves causeing rotation. Its just an electromagnet
Nice work!
Foarte tare!
Salut.multe aprecierii,bine lucrat
I want you to know I don't really cuss... So HOLY SHIT thats an amazing amount of work man, I am impressed. Id only for this for school and maybe a job, and this is just... wow.
amazing work
Well done!!
Wow this looks like a nice, production-grade motor.
You are really smart!! Very interesting video! Thanks!
Sorry if someone has already asked but I was just wondering what the efficiency of the motor is when it is running at or near capacity. I gather the water temperature must be kept above the dew point at all times. That is a very impressive design and excellent quality of construction. You should be very proud of this beauty!!
Increible desarrollo. Felicitaciones!!!!!
Incredible development. Congratulations!!!.
Try to do the standard test s (ANSI or IEC) in order to benchmarking.
Measure no load losses, efficiency, etc.
Congrats again!!!!!
You are frigging awesome!
You're amazing! Hope you are adequately employed (then again - you must be pretty well off to afford all of this)
too awesome. love the unique design need to show some links for the build of so it can be replicated if thats ok with you
Nice job m8.
You are awesome iulian

FELICITARI IULICA
nice job dude!
Very nice video, thanks for that!!!
I MUST SEE MORE!
wooooow, MASTER !!!! Im your fan from now on !! i'm like the younger version of you jeje look at my channel. XD
But what you did with this 45 kw bldc is so cool man
WOW GREAT JOB
maestro!
Nice video, I apreciate so much the knowledge inside it, thank you!
I was thinking on build motor too, but hexaphasic brushless system, so do I'll know if you had some advice for my experiment.
Thank you by the video.
VERY NICE A LOT OF WORK
your are an inspiration...
Fantastic job on your project. Any good resources for designing the coil to your application?
very nice job
Great motor and excellent skills, If that motor was made as an outrunner rather than an inrunner, it would increase its torque by more than one third and could be used to power a small aircraft. Well done.
VERY IMPRESSIVE!!!
Beautiful.
Very nice!
That's sick! You should put it on a e-bike or something.
Nice motor! Could you please post some no load figures (Amps and rpm for two or 3 different rpm) as well as the terminal resistance Rm and Torque-constant Kt or Speed-constant Kv of your motor? Thanks for sharing!
you should make these as a business - looks good. I would buy 2 for both rear wheels if can connect easy enough...
nice pro-work!
That motor is a Polyphase, Permanent Magnet, Synchronous motor. It may be driven by a polyphase inverter that runs on DC, but *Brushless DC motor* is a misnomer. Very nice work, by the way!
great job
Did anyone else see a spark at 1:47 in the upper left hand corner?
Very very cool motor. I've recently become obsessed with electrical motors and Li-ion batteries. I hope you put that monster in a motorcycle ;)
That's the laser from the tachometer, not a spark
Absolute perfection I would luv this motor I'm interested to know with such low voltage/amps and high tork could you run it from the earth like they used too with telecom cables then gear it up to a alternator
350pauli is that even possible, and do explain more or send me a link cause that’s some Nichola Tesla shit
How many parallel paths you chose?
Did you laser cut the stator or do you have a stamping die?
nice work
