9 A three-phase Y-connected 220-V , Shp, 60-Hz and six-pole induction motor has the following parameter values in 2/phase referred to the stator: Ra=0.3, Rz=0.15, X1=0.5, X2=0.2 and Xm-13. Compute the speed, output torque and power, stator current when the motor is operated at rated voltage and frequency with power factor and efficiency are 0.85. What is the total friction, windage and core losses? (12 Mark), [LO 1,2,4,5,6,7)
