The Wattmiser II system has better overall system efficiency compared to other methods of controlling the speed of a motor such as secondary resistance, eddy current clutches and adjustable frequency drives (AFD's). The reason for this is that the controller handles only a portion of the motors' rated output power.
Power factor is .95 or better over the entire operating speed range without external power factor correction capacitors. Power factor is set electronically within the Line Inverter controller.
