Numerical Calculation on Series Resistance Starting of Wound- rotor Induction Motor

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