英文摘要：

Bearingless switched reluctance motor,which had combined characteristics of switched reluctance motors and magnetic bearings,controled rotor radical positions with magnetic force.The production of the radical suspending force and the torque in a reluctance motor with magnistor was analyzed.Based on the four especial positions of rotor in a switched reluctance motor,the magnetic field in the motor was obtained employing the finite element method when rotor was in the center and has the radical displacement.Flux distribution, the relationships between the radical suspending force and the radical displacement and between the torque and the radical displacement were obtained,which laid a foundation for describing the models of radical suspending force and torque in a reluctance motor with magnistor.
