This paper presents a novel hybrid pole BLSRM(bearingless switched reluctance motor) and its radial force control scheme. The radial force can be produced by the radial force winding which is wound at separated radial force poles. And the rotating torque is produced by the excitation current of torque windings which are wound at torque pole. The proposed radial force control scheme is independent...
In order to solve problems of taking traditional mechanical bearing to bear the shaft, a novel bearingless switched reluctance motor with hybrid stator poles is proposed in this paper. The rotor needs only one bearing for rotating and constraining the axial movement. The other end can move freely in the radial direction. But it is balanced with the radial force produced by the motor. The proposed...
As generally recognized, the driving performance of SRM at higher speed will be degraded due to the effects of back electromagnetic force (EMF). In this paper, a multi-level converter is proposed to have an enhanced performance at a high speed range. The converter boosts voltage during phase excitation for a four-phase switched reluctance motor(SRM). By using one additional capacitor and switch, an...
