A three-phase 1750rpm 460V 60Hz 4-pole, Y-connected induction motor has the following parameters: Rs =0.66,Rr =0.38?,Xs =1.14?,Xr =1.71?, andXm=33.2?. 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. Calculate the maximum torque and the corresponding speed for 60Hz and 30Hz.
