Question 3 (a) Analysing the working principles of induction motors, explain why the rotor of induction motor cannot run at the synchronous speed. (b) The power input to the rotor of a 440-V, 50-Hz, 3-phase, 6-pole induction motor is 60 kW. The efficiency of the motor is 82%. It is observed that the rotor e.m.f. makes 90 complete cycles per minute. Analysing the performance characteristics of induction motors, calculate: (i) The slip (ii) The rotor speed (iii) The rotor Cu loss per phase (iv) The mechanical power and torque developed The output power if stator losses are 1000 W
