The rotary phase converter consist of two components. An “idler generator” and a “control panel” . The control panel includes a start circuit to start/stop the idler generator and capacitance to balance voltages between phases. The idler generator is energized by the single phase power spinning a rotating mass.

8The engineers at GENTEC American Rotary and Baldor Electric designed this ideal rotary generator with integrated Soft Start to drastically reduce inrush current (see specifications table below), and specifically for use in rotary phase converter applications. Please email or call toll free for a sizing recommendation for your application.

A rotary phase converter uses a standard three phase motor as an idler motor to help balance the voltage. Additional motors in the circuit only help to balance the output voltages. Because the single phase ‘in’, or real power is the same as leg 1 and 2 ‘out’; these leads must be used in the control circuit of the machine.
