绕线式异步电动机转子串电阻起动的计算

Calculation on Series Resistance Starting of Wound-rotor Asynchronous Motor

根据异步电动机 T型等效电路对应的电流、转矩方程式 ,用数值方法计算了绕线异步电动机转子串电阻起动的起动电阻 ,并与传统的近似方法进行了比较。通过实例计算 。

This paper applies numerical method to calculate the starting resistance of wound rotor motor by equation of current and torque based on equivalent circuit of T model of an asynchronous motor,and compared with traditional approximate method.In example it is indicated that calculate the starting resistance by numerical method in the cases of high starting condition is necessary.
