A six pole three phase 440V 60 Hz induction motor has the following model impedances

A six-pole, three-phase, 440-V, 60-Hz induction motor has the following model impedances:

RS  = 0.Q   XS  = 0.RR  = 0.Q   XR  = 0.Xm  = 35 Q

Calculate the input current and power factor of the motor for a speed of 1,200  r/min.

14.68      An eight-pole, three-phase, 220-V, 60-Hz induction motor has the following model impedances:

 

RS  = 0.78 Q

XS  = 0.56 Q

Xm  = 32 Q

RR  = 0.28 Q

XR  = 0.84 Q

 

Find the input current and power factor of this motor for = 0.02.
