b) A three phase induction motor is supplying a constant load torque of 500N.m. at a line to line voltage of 500Vrms. The maximum torque corresponding to this voltage is 1000N.m. If the line to line voltage is reduced to 25OVrms: i) Find the corresponding maximum torque ii) can the motor operate with this reduced voltage? iii) What is the maximum voltage reduction that can be allowed, without motor stalling? Solution i) maximum torque is 1000N.m. ii) yes, the motor will operate with the reduced voltage because it has a constant load torque of 500N, which is a three phase induction motor supplying a constant torque. iii) The maximum voltage reduction that can be allowed,without motor stalling is 500Vrms-250Vrms=250V rms. .
