摘要
双罩极圈罩极电动机由于结构复杂使得对其完整的定量分析变得十分困难。采用双旋转磁场理论,对罩极电动机进行了分析并推导出总的电磁转矩公式。利用该公式就可得出罩极电动机的运行特性曲线和计算相应的有关变量。
Complex structure of dual shaded - pole motor brings much difficult in complete quantitative analysis. Dual shaded - pole motor is analyzed by dual rotating magnetic field theory, then general formula for electromagnetic torque is derived in this paper. Using the formula, the operation curve of shaded - pole motor and relevant variables of the corresponding calcula- tion can be obtained.
