I need some help understanding this. As I stated in a previous thread (ac to dc power) I have a permanent magnet motor which is electronically commutated to develop variable speeds. Input voltage is ac. It is then rectified to dc for control and then through an inverter curcuit with 6 transistors thru 3 leads to the (labeled) single phase ac motor. There is a separate ground which attaches to the body of the motor. When this motor is separated from the electronics and spun backwards it produces ac voltage since it is a permanent magnet motor. I show voltage from any combination of the 3 leads as it operates as an alternator. My question is this: Is this true 3 phase voltage being produced and if so how can I test this? Help is appreciated.
