Title: Zero electric motors: Polyphase?
Post by: TargeT on July 17, 2013, 11:05:50 PM

I'm new to the whole eletric motor world & just trying to learn, I would assume (especially the new 2013 motors) are polyphase, is this the case?

Is the motor AC & the rest of the system DC? (I assume a brushless motor means it's AC polyphase)

these motors are very smooth, are they 12 (or more) phases?

They're not 12-phase.... they're 3-phase, but they have multiple poles on the motor.

The batteries are DC and that goes to an Inverter that creates 3-phase AC on it's output. That is tied to a 3-phase BLDC/PMAC motor.
