whye the current increases in the motor when the load on the motor increases..

its like law of conservation of energy , as load or output
of motor increases so do input increases .. so current in
motor increases and flux increases to meet the demand

whye the current increases in the motor when the load on the motor increases..

Answer / gajendran.al

When load on the motor increases, it tries slow down. This
reduction of speed reduces the back emf produced [which
acts as the current limiting impedance]. Due to this the
current drawn by the motor increases

whye the current increases in the motor when the load on the motor increases..

Answer / 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.
