A rotary phase converter is the most popular and universal type of phase converter. 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. This rotation generates a third line of power which is coupled with the 2 single phase line to make 3 phase power.
What will a rotary phase converter run? A rotary converter will run every type of load (motor, resistive and inductive loads).
There are 3 types of rotary phase converters:
Standard Rotary Phase Converter
Pro-Line(PL) with digital start circuit. Pro-Line Rotary Phase Converters are a general purpose economical all around phase converter for every type of load. Good for food service equipment, woodworking and metalworking machine tools.
Digital Rotary Phase Converters
Smart-Boost™(SB) with digital current boost mode. Smart-Boost™ Digital Rotary Phase Converters are a power-packed converter with current booster for those hard starting / high inertia loads. Better for fans, blowers, dust collectors, larger flywheel, pumps, and compressors.
Smart-Phase™ (SP) with active digital voltage balancing. Smart-Phase™ Digital Rotary Phase Converters have electronic stability control powered by an 8 stage automatic voltage regulation controller. Best for CNC machines, AC drives, and voltage-sensitive equipment.
