Designed especially for running three-phase 230V Machine Tools and Motors from single-phase 230V power
Phase-A-Matic Static Phase Converters have been developed, tested, and thoroughly proven over a 46 year period demonstrating exceptionally high reliability and long life. These converters are the workhorse of many commercial uses and multitudes of home shop machines.
Using the Phase-A-Matic™ Static Converter only will produce approximately 2/3 normal HP.* This method is inexpensive, the most popular, provides excellent results on most machines tools and numerous other uses. Motor speed is not changed. Most two-speed motors, power feeds, coolant pumps, etc., will operate normally. Motor will instant reverse. There is nothing to change. All switch gear will work normally.
Full or close to full HP can usually be obtained by running a three-phase motor and Phase-A-Matic Static Converter combination as shown on the Installation Instructions. 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 at least 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, 230V motor is the best choice. 1800 RPM motors can be used on applications not heavily loaded. Used three-phase motors are inexpensive and readily available.
