摘　　要：为了提高三相电容式电机的效率和功率因数,有效地消减电机的谐波磁势,对新型三相电容式电机在变频调速系统下的性能进行了详尽的分析,并通过实验研究对新型三相电容式电机与普通三相异步电机在不同频率下的转矩特性、电流特性及功率因数等进行了对比性研究。实验数据表明,该新型电机具有一定的应用优越性和可推广性。In order to raise efficiency and power factor of 3-phase capacitor clectric machine and to weaken the harmonic magnctomotive force, the performance of this new kind of machine under frequency speed control system is analysed. The comparative experiments are conducted about power factor, torque character and electric current properties between the 3-phase capacitor electric machine and the asynchronous motor. The rcsult of the comparative experiment illustrates that the 3-phase capacitor electric machine enjoys superiority and can be used widely.
