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 Ω, 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.
