is 3-phase induction motor need a starter ? why do it so
Answers were Sorted based on User's Feedback
Answer / pradeep kumar patel
yes, bcz 1-starting current is (5-6 times)greater than
supply current .2-starting toque is (1.1 times) greater
than normal torque.

Answer / 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.

Answer / anilrajkumar
to limit the starting current and thereby reducing the starting torque,preventing the damage to the motor due to high current

Answer / saumil patel
i=(V-Eb)\r
so at starting in induction motor back emf is 0.so current will be more than 5 times of full load current,so it need starter for safely starting....
