Q6. A 3ph 440 V 60 Hz 8 pole induction motor runs at a power factor of 0.85 lag and drives a load of 8 kW at a speed of 14.4 rev/sec. The stator loss is 1 kW and the rotational losses (windage and friction) amount to 0.8 kW. Calculate EACH of the following:

(a) The synchronous speed;

(b) The rotor copper loss;

(c) The input power to the motor;

(d) The motor current.
