Abstract
A quasi regulated electric generator, comprising a stator having teeth on an inner periphery defining slots therebetween, stator windings disposed in the slots forming output phases, a rotor rotatably mounted within the stator, the rotor having permanent magnets mounted thereon forming rotor poles which induce a voltage in the stator windings when the rotor is driven by an external prime mover, and a series saturation circuit coupled to an external source of dc current for saturating the stator, decreasing the induced voltage thereby. Magnetic slot closers are placed in the slots in which are disposed the series saturation circuit to aid tooth saturation.
