英文摘要：

In traditional bearingless switched reluctance motors （BSRM）, consideration must be given to winding conduction area choice so that both radial force and torque can be produced effectively, which imposes a severe constraint on the study of control methods. In order to address this problem, a single-winding hybrid-stator bearingless switched reluctance motor （HSBSRM） is studied in this paper. Firstly, the basic structure, the running principle, and the electromagnetic force characteristics are compared with those of traditional single-winding and double-winding BSRMs. The independence of radial force winding and torque winding can be enhanced, and the performance of radial force can be improved as well, which is positive for suspension control. Then the mathematic model for radial force and torque are computed based on Maxwell stress method, and the corresponding control algorithms are designed, which are both verified by simulations and experiments. It can provide more sound theoretical bases for optimal motor design and control strategy study. And the choice and study of control methods are more flexible.
