Re: Q about multi-phase motors.



>Why only up to three-phase motors?

I think one of the reasons folks on the list are interested in three-phase
motors is because inexpensive three-phase industrial motors are available
'off the shelf'.

If you went to 5 or 7 phases, then you'd have to have a custom made motor.
