Calculate the value in ohms of the rotor resistance, Electrical Engineering

Assignment Help:

The synchronous speed of a wound-rotor induction motor is 900 r/min. Under a blocked-rotor condition, the input power to the motor is 45 kW at 193.6 A. The stator resistance per phase is 0.2 , and the ratio of effective stator turns to effective rotor turns is 2. The stator and rotor are both wye-connected. Neglect the effect of the core loss and magnetizing impedances. Calculate:

(a) The value in ohms of the rotor resistance per phase.

(b) The motor starting torque.
