Determine the 50- hz applied voltage, Electrical Engineering

Assignment Help:

Athree-phase, 440-V, 60-Hz, four-pole induction motor operates at a slip of 0.025 at full load, with its rotor circuit short-circuited. This motor is to be operated on a 50-Hz supply so that the air-gap ?ux wave has the same amplitude at the same torque as on a 60-Hz supply. Determine the 50- Hz applied voltage and the slip atwhich themotor will develop a torque equal to its 60-Hz full-load value.
