定、转子的漏抗比对感应电动机性能的影响

The Effect of the Ratio between Stator's Leakage Reactance and Rotor's Leakage Reactance on the Induction Motor's Performance Characteristic

首先推导出精确的最大转矩公式，然后利用Ｔ型等效电路实例计算了４台三相感应电动机在定、转子漏抗之和等于常数的条件下，不同的定子漏抗与转子漏抗的比值，对感应电动机的额定性能。起动性能和最大转矩值的影响，为实际工程计算提供了方法和有关参考数据。

The exact expression of maximum torque are derived at first, then four in-duction motors which using exact equivalent circuit are calculated. The rated perfor-mance characteristic, starting performance characteristic and maximum torque are ob-tained, under the condition that the sum of stator's leakage reactance and rotor's leak-age reactance is constant and the ratio between stator' s leakage reactance and rotor' s leakage reactance is different.
