Motor-Generator

Electrical Machine

A motor-generator is a device that converts electrical power from one form to another, used to convert the frequency, voltage or phase of electrical power and sometimes to isolate an electrical load from its power supply line. Large motor-generator sets were widely used to convert industrial amounts of power, while smaller ones were used to convert battery power to higher direct-current voltages.
