Higher stator resistance induction motor
WebEquation 1. In the supply-frequency equivalent circuit, the secondary e.m.f. is E 2, rather than sE 2, so to obtain the same current in this model as given by equation (1), we require the slip-frequency rotor resistance and reactance to be divided by s, in which case the secondary current would be correctly given by.
