7. A three phase 11.2 kW 1750 rpm 460V 60 Hz four pole Y-connected induction motor has the following parameters: Rs = 0.
7. A three phase 11.2 kW 1750 rpm 460V 60 Hz four pole Y-connected induction motor has the following parameters: Rs = 0.66 S2, R, = 0.38 2, X, 1.71 2, and Xm = 33.2 2. The motor is controlled by varying both the voltage and frequency. The volts/Hertz ratio, which corresponds to the rated voltage and rated frequency, is maintained constant. a) Calculate the maximum torque, Tm and the corresponding speed om, for 60 Hz and 30 Hz. b) Repeat part (a) if Rs is negligible.
