Use a 220/440V motor as the phase converter. Wire for 440, and drive
ONE HALF of the line connected phase. The converter will be working as
a rotary step up, eliminating the need for the seperate transformer. I
have a machine that uses this trick to avoid the need for a step down.
Not all dual voltage motors can be used in this way.
How is this possible? Unless you have full supplied single phase 220V and a
start cap for the third leg, you wouldn't even be able to start the idler
motor. Right?
