Starter means at the time of starting our motor takes more
current due to low emf in starting so its function is to
limit the starting current. we know in starting motor takes
5 to7 times current of rated current.
for starting induction motor we use three method which
are further giving
1.Direct on line starter.
2.AutoTransformer.
3.Star-Delta.
