a) A 4-pole, 346 V, 1425 rev/min, 50 Hz three-phase induction motor
is controlled by a Variable Voltage Variable Frequency (VVVF) drive such that the synchronous speed is reduced to 900 rev/min. If the motor runs at constant flux operation and the slip is kept unchanged, evaluate i. the input frequency; and ii. the motor speed in rev/min. b. How does regenerative braking work with VVVF drive?
