A 15 kW, 415 V, 4-pole, 50 Hz delta connected motor gave the following results on test (voltages and currents are in line values)

Using the approximate circuit model, determine

(a) the line current and power factor for rated output,

(b) the maximum torque, and

(c) the starting torque and line current if the motor is started with the stator starconnected. Assume that the stator and rotor copper losses are equal at standstill.
