Hi , I have a BLDC motor with 14 poles and 12 cogs. So, does it have 4 points of maximum attraction (at any given time) ? and does it take (cogs*maximum_no_attraction_point)12*4 = 48 steps to make one complete rotation ?
This is awesome do you know a way you could use a standard BLHeli_32 ESC to make the motors start spinning slowly until they reach. 3% throttle arm speed?
That is realy impressive ! Very well done !! :) I'm trying to make something like that too but I have issues about buying the L6234 chip in France... On your blog your talking about making one with MOSFET and ICs, could you explain me a bit more about it? Thank you very much !
Is it possible to make something similar but that it can also go very fast? You know, going super slow and transition to very fast smoothly. I suppose you would require a feedback, but I can't find a driver that could do that for slow and fast speed
Hi, I was wondering how you deal with torque cogging? In many applications the BLDC motor does not rotate with uniform speed due to cogging. Thanks.
Big flywheel
@@yelectric1893 a geared flywheel. Flywheels don't make sense at these kinds of speeds unless they are geared to be faster
Sinusoidal drive, that's how
Hi, nice work!
Did you observe whether there was high temperature on the motor after few moments driving at very low speed?

Nice work, do you have a circuit diagram?
firstly i want thanks a lot ... I need motor driver shema but i cant find it. Please halp me

That is *seriously* impressive. (...at least to me, anyways. :grin: )
Keith Olson Thank You :)
Check my Brushless motor controlled via arduino here: ua-cam.com/video/uUrcpAUttt8/v-deo.html
Is it possible to have direct RPM control (or at least put out the electrical RPM so the delay can be altered open loop)?
Probably just a software thing, maybe with an Arduino if there isn't already some kind of microprocessor in this
Anywhere i can look for the code please?
