实体转子隐极同步电动机的起动计算

Starting Calculation of Solid Rotor Synchronous Motor Involving Non salient Pole

本文对铁磁实体转子隐极同步电动机异步起动时的转矩与电压关系进行了研究。由电磁场基本方程推出了实体隐极同步电动机异步起动时的电磁转矩公式。结果表明 :降压起动时 ,转矩与电压的 1.5次方成正比 ,而不是通常认为的 2次方。

This paper studied the relationship between torque and voltage, when the solid rotor synchronous motor involving non salient pole started asynchronously. The electromagnetic torque formula was given.The result shows that during reduced voltage starting,the motor torque is directly proportional to the 1.5th power of voltage but not the 2nd power as usually regarded.
