SYNCHRONOUS ELECTRIC MACHINE

摘要

This invention relates to a synchronous electric machine including a stator and a rotor, wherein the stator includes a multi-pole stator winding set, the rotor includes a multi-pole cylindrical rotor design or salient pole design with at least two-phase rotor winding set on the cylindrical rotor having the same number of poles as the stator, and the stator windings provide excitation to the rotor by means of stator current imbalance or superimposition, by secondary windings to produce harmonic flux or by a three-phase winding with an external source of excitation. Furthermore, the invention relates to a method for operating a synchronous electric machine.
