Designed especially for running three-phase 220V Machine Tools and Motors from single-phase 220V power. Runs three-phase motors from a single-phase power at 2/3 rated HP.
Method 1: Reduced HP
Using the PHASE-A-MATIC static converter alone will produce approximately 2/3 normal HP.* This method is inexpensive, the most popular, provides excellent results on most machine tools and for numerous other uses. Motor speed is not changed. Most 2-speed motors, power feeds, coolant pumps, etc. will operate. Motor will instant reverse. There is nothing to change. All switch gear will work normally.
Method 2: Full or close to full HP
Make your own type of ROTARY CONVERTER using the static converter in conjunction with a three-phase motor used as an idler motor can produce full or close to full HP. When running unloaded, the windings of the motor function as a rotary transformer or generator while consuming very little extra power. The idler motor needs to be a minimum of 50% larger than the largest motor that you want to run to accommodate the higher starting current. A good quality, 3600 RPM three-phase wye-wound 220V motor is the best choice. 1800 RPM motors can be used on applications not heavily loaded.
