A 12 pole three phase induction motor with supply frequency of 50 Hz. If the slip is 3 % at a certain load, determine (a) the synchronous speed, (b) the speed of the rotor (c) the frequency of the induced e.m.f. in the rotor and (d) speed of the induction motor if the slip changes to 6 % Synchronous speed Answer for part 1 Speed of the rotor Answer for part 2 frequency of the rotor emf Answer for part 3 Speed of the motor if slip is changed to 6 % Answer for part 4
