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 = 0.14 0 Χ, = 0.56 Ω X₂ = 0.28 0 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 X = 13.25 Ω m iii) The copper losses iv) The rotor input power v) The output torque
