Ilusys Systems - 2017-05-16
my BLDC playlist: https://www.youtube.com/playlist?list=PLyzlj5IaDE0fsTsjA6JsrlD7aiknbGU9K A quick and dirty demonstration of DIY motor. This motor should be synchronous driven by square wave H bridge mosfet driver. driver is using hall effect sensor for feedback. theoreticaly two similar motors like this could be locked in speed and phase depending on used materials this motor can be really cheap. Unfortunately it requires driving circuit, and DC voltage, so it cannot be run directly from mains voltage. However driver is quite simple and in principle working at mains voltages is possible.
Sir driver schematic diagram please
dude keep it up! science is everything loved u vid man
hey, thanks :)
Thanks. Great video
sir.. any driver schematic doc.. link please..?

It is a little bit simplified with optional use of single output hall IC.
there are a lot of modern IC's that will work better and provide a lot of protection, debugging and fail safe features... I used this, because I have a ton of motherboards, and I am lazy to order parts and make PCB
Very nice presentaion super
good drayver ! he who does not know will not understand. or make flat coils of 7 mm or with Fe cores. If coil long ( mre 7 мм) - to only ferum cores? and closed magnetic fields .Good luck . like !!!! big Лайк !
8:58 That type of coil is called a serpentine coil.
THX. I foud orig vid that inspired me in the meantime. In fact it's "quite known" type of winding. But still I find it quite original.
@Ilusys Systems it is a different way of winding a coil, but a 3 phase machine with a serpentine coils is less efficient at packing copper turns on an axial flux, than using more conventional coils. That said, I'm still building my motor with a serpentine coil because of its simplicity.
@Keith Reynolds That's true... I was thinking about twisting coil to resemble fan blades, that way it can be packed more tightly. Then you can offset stator plates to correct flux alignment.
Well if you don't have a lot of turns it can be done.
I was experimenting with offseting stator plates, but I couldn't see any difference...
@Ilusys Systems i have finished my motor now. But, instead of using serpentine coils, i used a slightly different arrangement. Instead i used 3 axial flux arranged faulhaber coils.

Put this system on scooter front wheel to make hybrid bike.
you wold need a transmission... magnetic flux is weak for direct drive.
can you traduce to spanish??
Well I wanted to learn spanish years ago.
Only thing I can translate is "Si, senora" and "Muchas gracias"
So it would be "google translate" quality
You sound like Tesla. nice work!
Lol did you hear him? I mean at that time sound recording devices started to develop... I don't remember listening to his voice
Yup, I sure have. I've met him a few times actually.
Well you must be really old then :)
Yup I sure am.
Snsnsn..lol. ya got me. Thanks for sharing
у него странный акцент

Your H. bridge driver is a work of art!!
