I have several Brand new 3 phase motors that I would like to use to make rotary phase converters. I am finding that there are a lot of different ways to configure them. Not only with the control circuit but also with the capacitor setup itself.

Does anyone have any opinions or ideas on what is the best setup? Can you point me to any schematics and/or general rules of thumb for sizing capacitors for balancing the phases?
These converters will be made using motors anywhere from 2 to 10 HP.

Thank You.
