A Consideration of transient torque characteristics is of special importance for cases where induction motors are started and stopped frequently or continuously, since under such conditions a quick response is often required. The required response is such that sometimes a full speed rotor must come to a dead stop in less than one revolution. In this paper we obtain the computing methods (1) transient braking torque performance under dc excited conditions (2) transient accelerating torque characteristics under conditions of suddenly applied ac voltage.
Based on the methods, we investigate the effects of the rotor resistance and rotor speed on the transient dc braking torque characteristics, the relation between time lag of dc braking torque and parameters, the effects of switching time and rotor resistance on the transient accelerating torque characteristics when an ac voltage is suddenly applied.
