Method No. 1:
Using the Phase-A-Matic Static Converter only will produce approximately 2/3 normal HP.* This method is inexpensive, the most popular, and provides excellent results on most machine tools & numerous other uses. Motor speed is not changed. Most two-speed motors, power feeds, coolant pumps, etc., will operate normally. The motor will instant reverse. There is nothing to change. All switch gear will work normally. (*Refers to wye-wound motors; delta-wound motors will run at 50% rated HP. Delta-wound motors are very rare in the USA, occasionally being found on some imported equipment, and are particularly found on German and Italian machines)
Method No. 2:
FOR FULL OR CLOSE TO FULL HP: Configure as a rotary converter using Phase-A-Matic’s static unit ~~ Full or close to full HP can usually be obtained by running a three-phase motor and Phase-A-Matic’s Static Converter combination as shown in 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 you want to run to accommodate the higher starting current. A good quality 3,600 RPM, three-phase wye-wound, 220V motor is the best choice. 1,800 RPM motors can be used on applications not heavily loaded. Used three-phase motors are inexpensive and readily available. When using this method, it is possible to run multiple machines as long as the idler motor is large enough to handle the largest load it would ever have at any one time. For instant reversing of the load motor, as in rigid tapping, the idler motor must be a minimum of twice the HP rating of the load motor and perhaps more. The static converter is sized to the HP of the idler motor, not the load motor(s)
