Why we use startor to the motor?

Answer / suganya
To limit the starting current we are using starters. In
motors the voltage equation is, v=Ia.Ra + Eb. At the time of
starting no back emf will be there i.e Eb=0. therfore
v=Ia.Ra since the resistance is negligible v=Ia i.e armature
current will be equal to the supplied voltage and speed will
be high. so to limit this current we are going for starters.

Answer / chandu
for giving protection to the motor
from overloads and adjusting the
speed of the motor. now a
days,starters are replaced by drives
for automatic control.there are
various types of starters.

Answer / bhabanipattanayak
Starter is mainly used for
limiting the high starting
current to a safe value. It is
also provide with different
equipment to protect the
motor from overload & low
voltage.
