Explain the construction and working principle of 3-phase induction motor.
A 4 pole, 3 phase, $50\ \text{Hz}$, 1440 rpm induction motor is drawing $35\ \text{kW}$. The stator and friction losses are $1\ \text{kW}$ and $1.5\ \text{kW}$ respectively. Find.
(i) rotor copper losses
(ii) efficiency of motor
Explain why do we need a starter to start an induction motor? Also explain different methods of induction motor starting.
