I'm trying to understand the "theoretical" effect of driving one coil at a time in a three phase motor. I.e. you basically have one pole that is north on at a time.

Would it be coggier?

What would the effect on torque be precisely? Would it be disproportionately less torque? (does the average magnetic gap increase?)

Would it affect speed constants?

Affect on efficiency?

???

I'm just considering my options for a cheezy application that does not need as much motor as I have, where if there wasn't a huge efficiency penalty for just having low side drivers, I would be sorely tempted to do so: etek brushless on a honda 50, w 24 volts in batts.

Is it even doable? maybe there isn't an appropriate hall event even or coil pattern. I guess I would have to figure out a center tap to even consider it and hope it is a Wye.

Thanks for your consideration.
