Abstract
A modular assembly for an electromagnetic machine is disclosed. The modular assembly includes a rotor assembly and a flux controlling assembly. The rotor assembly has a shaft and has a plurality of rotor laminations mounted on the shaft. The rotor laminations define at least four salient rotor poles. At least one permanent magnet is embedded in each of at least two of the salient rotor poles. The flux assembly has a stationary coil disposing about the shaft for controlling flux of the disclosed machine. The flux assembly also has a cage supported on the rotor assembly for transferring flux between the at least two salient rotor poles with embedded magnets and the coil. In one embodiment, a support member is mounted on the shaft and supports the cage thereon. In another embodiment, a support member is connected between the cage and the at least two rotor poles with embedded magnets.
