Abstract
An improved reluctance motor with reduced windage losses and reduced internal rotor stresses is proposed. The reluctance motor is constructed with continuous, non-magnetic supported members in the interpolar spaces of the salient pole rotor. End plates may be added to the rotor which are attached to the support members creating a "cage" structure which supports the rotor. In addition, the rotor through shaft may be eliminated by providing stub shafts on the cage end plates to transmit torque from the rotor. Various methods of constructing the rotor of the invention are also described.
