Question 3 A four pole, three phase induction motor with a stator to rotor ratio of 0.8, runs at a speed of 1450rpm at no- load and 1350rpm at full load. The motor is energized from a 400V, 50Hz star connected source. Determine: a. the synchronous speed [04 marks] b. the frequency of the rotor voltages at no-load s-f [08 marks] c. the frequency of the rotor voltages at full load [08 marks] as d. the rotor induced voltages per phase [05 marks]
