2. Generator Basics IEEE

2016-10-5· As the PMG rotor rotates, it produces AC voltage in the PMG stator. Circuit: Generator with a PMG This voltage is sensed by the regulator, compared to a reference level, and output voltage is adjusted accordingly. A three-phase AC voltage appears at the exciter rotor and is in turn rectified by the rotating rectifiers.

Rotor (electric) - Wikipedia

2019-7-29·Early development. An early example of electromagnetic rotation was the first rotary machine built by Ányos Jedlik with electromagnets and a commutator, in 1826-27. Other pioneers in the field of electricity include Hippolyte Pixii who built an alternating current generator in 1832, and William Ritchie's construction of an electromagnetic generator with four rotor coils, a commutator and
