whye the current increases in the motor when the load on the
motor increases
Answer Posted / s s nanal
Full load speed of Induction Motor is near the sunchronous
speed. (Ns = 120 f/P) With increase in load the motor slows
down.Hence back emf developed also reduces.Hence motor
draws more current from supply in order to retain its speed
near synchronous speed.
