Phase Converter

[GoldDigger]

Nice explanation. Thanks. While you are here, one more thing about phase converters that I have never understood: As I understand it, all phase converters (even the phase perfect ones) "pass through" the two single phase legs, and manufacture the third. So isnt the phase angle between all three NOT 120 degrees? How come the motor doesnt seem to care?

With two legs attached to the windings of a free spinning induction motor and the "manufactured" phase coming from the third leg of the same motor, why would you expect it to be very far from 120 degrees.
The mechanical rotation between the motor coils is 120 degrees.
