If an induction motor is restarted before its rotor stop
rotating, then what will be the amount of current drawn?
Is this current will be the same as motor starting current?
Answer Posted / lova subrahmanyam
in induction motor starting current is 3 times more than the
full load current at the time of starting.why because the
rotor is in stand still condition,(ie back emf of rotor is
'0').that's why to induce the emf in the rotor it takes more
current to produce the torque.onece the motor reaches the
rated speed it will take normal load current.if u cut off
the suupply
