Three phase induction motor Leakage Reactance five times Resistance for stator and rotor and impedance for stator and rotor is equal . Slip at full load is 0.02 .calculate the resistance that added for starting current equal three times full load current , Calculate starting torque in this case . if the slip ring is short circuited calculate the ratio of starting current in two cases .no. of poles is 4 and frequency is 50 Hz .
