单绕组磁悬浮开关磁阻电机径向力数学模型
A Radial Force Mathematical Model of Single Winding Bearingless Switched Reluctance Motors
摘要
Abstract
Magnetic saturation effects are usually ignored in the derivation of mathematical model for single winding bearingless switched reluctance motors(SWBSRM). Aiming at the problem,this paper builds a radial force mathe-matical model considering the characteristic of magnetic saturation with the Maxwell stress tensor method and the mag-netic equivalent circuit. Taken a prototype as the example,the finite - element simulation model is established. Simu-lation results show the validity and superiority of the model by comparison with the FEM simulation and the mathemati-cal model based on the virtual work method. The result can provide more accurate theoretical basis in the research of motor operation characteristics analysis,optimum design and control strategy.关键词
