Analysis and Calculations on the Parameters and Performance of Single-Phase Capacitor Motors by Multi-Loop Method

本文用多回路理论推导了定子具有不对称绕组的单相电容电机的参数和性能计算公式,考虑了电机定、转子谐波磁势的影响,还考虑了主磁路饱和及漏磁路饱和引起的参数变化。利用所推导的数学公式编制了计算机设计程序,通过对几种单相电容电机的计算和实验测试,证明这种计算方法和设计程序是可用的。

Equations to determine the parameters and performance of single-phase capacitor motors with asymmetrically distributed winding by the multi-loop method are de veloped in this paper. The effects of the space harmonic magnetomotiv force and the parameters variation caused by the saturation of the main and leakage magnetic circuit are considered. Using the computer programme, the author calculated the performance of the single-phase capacitor motors, the testing results indicate the method and the programme are feasible.
