定子电阻对凸极同步电动机功角特性的影响

Influence of Armature Resistance on the Torque-Angle Characteristic of Salient Pole Synchronous Motor

利用同步电机的磁链方程和定子电压方程,推导出计及定子电阻时凸极同步电动机功角特性的精确显式表达式。研究了不计定子电阻和计及定子电阻两种情况下,功角差值随负载的变化规律,得到了一些有用的结论。

The exact expression of salient pole synchronous motor's torqueangle characteristic is derived using the equation of flux linkage and stator's voltage. The synchronous motor's torqueangle characteristic including and without stator's resistance are obtained respectively. The influence of stator's resistance on the power angle is discussed. Some useful conclusions are obtained.
