Reluctance electric machine.

摘要

The stator (S) is connected to an AC supply (R) through a current vector amplitude and phase control circuit (C). The latter comprises e.g. an energy recovery chopper-rectifier and four-quadrant transistor inverter. The ferromagnetic elements (L) of the rotor are interspaced between inserts (I) of e.g. Al or synthetic nonmetal set into cavities which extend in a plane tangential to the air gap (T), with a width not exceeding five times that of the gap. The ratio of the ferromagnetic portion to the total cross-section of the rotor is not greater than 0.6.
