Common Shaft Motor Generator Sets

Synchronous Motor Frequency Converter

The most sophisticated and precise rotary frequency converter is a synchronous motor - synchronous generator converter, both units made on a single common shaft. In this case, the frequency change is made by winding the motor with a different number of electrical poles than the generator. For example, a 12 pole motor and 10 pole generator will yield a 60 Hz to 50 Hz conversion. Using a synchronous drive motor allows the rotational frequency to be "exact", that is, as precise as the electric utility grid. Manufacturing the converter on a single shaft also increases the reliability of the unit.
