摘　　要：针对单绕组宽转子齿结构无轴承开关磁阻电机(bearingless switched reluctance motor with wider rotor teeth,BSRMWR)的齿极绕组故障情况,基于该电机的本体结构与工作原理,提出一种兼顾转矩性能与悬浮力稳定性的补偿方法。建立适用于该悬浮力补偿方式的电机新型数学模型;为了在应用悬浮力补偿方式时的稳定悬浮,将一种新型悬浮力分配函数(force sharing function,FSF)引入电流斩波控制(current chopping control,CCC)策略。通过仿真软件及硬件实验平台,验证CCC&FSF控制方法对稳定悬浮力的有效性,以及基于CCC&FSF策略下的悬浮力补偿方法在绕组故障时的有效性。In response to the situation of open-circuited fault of single winding bearingless switched reluctance motor with wider rotor teeth(BSRMWR),a compensatory method that combines performance of torque and stability of suspended force is proposed based on the structure and working of BSRMWR.In order to achieve stable suspension in the compensatory method of suspended force,a new force sharing function(FSF)is introduced into the strategy of current chopping control(CCC).At the same time,a new mathematical model for the motor is established,which is suitable for the compensatory method of suspended force.The effectiveness of the CCC&FSF control method in stabilizing the suspended force and the compensatory method based on the CCC&FSF control method when the fault occurs to the winding is verified through simulated software and experimental platform of hardware.
