| 摘 要： | 齿槽转矩对永磁电机有着很大的影响,是产生振动和噪声的根源,所以削弱齿槽转矩对双凸极永磁电机的设计有着重要意义。与其他永磁电机相比,由于结构和运行原理的不同,双凸极永磁电机齿槽转矩的削弱方法也有所不同。介绍了几种有效的削弱方法,并进行了简单的分析。

| Abstract: | It is known that cogging torque cause great affect on motor,doubly salient permanent magnet motor(DSPM) included.Cogging torque is the cause of vibration and noise.Because of this,it's important to try to reduce cogging torque when designing DSPM.Because of the differences on structure and operational principle,the ways of reducing cogging torque in DSPM is different from other permanent magnet motor.Several effective reducing methods were introduced and brief analysis was given. |
