An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.
He created an electric machine called a synchronous phase converter, which was a single-phase synchronous motor and a three-phase synchronous generator with common stator and rotor. It had two independent windings: The outer winding is a single-phase synchronous motor. The motor takes the power from the overhead line.
The field produced by a single-phase winding can provide energy to a motor already rotating, but without auxiliary mechanisms the motor will not accelerate from a stop. A rotating magnetic field of steady amplitude requires that all three phase currents be equal in magnitude, and accurately displaced one-third of a cycle in phase.
Such converters may also allow the frequency to be varied, allowing speed control. Some railway locomotives use a single-phase source to drive three-phase motors fed through an electronic drive. [36] A rotary phase converter is a three-phase motor with special starting arrangements and power factor correction that produces balanced three-phase ...

THE TURNING POINT The idea started on New Year’s Day in 1980, when my boyfriend (now my husband), Tim, and I woke up in our flat in London. We’d been working in the U.K. for less than a year and living together only a couple of
