Cool motor ZPB! Do you have any specs on it? Like kv, max rpm, max current/power, etc?

No, it's not magnetized at all really.

I've seen this in the forklift AC motors at work. This is also something that throws a monkey wrench into the gears of my understanding.

I realize these are sensor based motors, but I've always wondered a few things:

#1. How does the stator conduct magnetism in such a way to get rotation? I'm sure it's in the winding. Please point me toward more information on this.

#2. Can these be used in a sensorless setup? Do they Generate enough EMF to go sensorless?
