摘要
介绍永磁转子双凹坑结构单相同步电动机的结构特点,并推导出用电阻、电抗等参量表示的电磁转矩计算公式。文中指出,该种电机结构简单、造价低廉,具有自起动功能,适宜于小功率驱动、计时、定时机构中使用。
It introduces the Structure features of single-phase synchronous motor of PM rotor with double-concave,derives calculating electromgnetic torque formula expressed as parameters of resistance,reac- tance etc..This kind of motor is suitable to small power drive,timing mechanism and timer etc.as it is of simple structure,low cost,and self- start capability.
