QUESTION 2 A 30 star connected 6-pole 60 Hz induction motor draws 16.8A at a power factor of 80% lagging with the following parameters of per phase approximate equivalent circuit referred to the stator. R₁ = 0.24 0 R₂ = 0.140 x₁=0.56 0 X₂ = 0.28 0 X = 13.25 Q The total friction, windage, and core losses may be assumed to be constant at 450W. For a slip of 2.5% and when the motor is operated at the rated voltage and frequency, calculate i) The speed in rpm ii) The rotor current iii) The copper losses iv) The rotor input power v) The output torque (15 marks)
