is 3-phase induction motor need a starter ? why do it so
Answer Posted / limna
since an induction motor is started on no load,it has a high starting torque.therefore they are switched on by providing high resistance using a starter.and once the motor has reached its rated speed the starter resistance is slowly cut out.
