Induction rated 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. WebTranscribed Image Text: A 400 V, 3-phase, 4 pole slip ring induction motor is supplied at rated voltage and frequency. The actual rotor resistance per phase is 3 2 and the stand still rotor reactance per phase is 12 2. Neglect stator resistance, reactance and magnetizing reactance. 1. Determine the value of resistance to be added to the rotor ...
