ABSTRACT:
A rotor assembly for a reluctance machine is disclosed in which the rotor assembly comprises a stack of rotor laminations having a plurality of rotor poles defining interpole regions. The rotor assembly also comprises a cage including an end plate and support bars, which may be electrically conductive, that are axially aligned within the interpolar regions that lie between adjacent rotor poles. When the support bars are electrically conductive, the support bars can become transient "flux blockers" as the rotor assembly rotates past a stator pole, blocking the flow of flux through the interpole regions and improving the performance of the motor.
