Answer Posted / siddarth.m
the main purpose of using a three point starter is
to limit the starting armature current.......
This is because dc motor the initial voltage difference is
less so high current passes through the armature windings
which is not a desired factor.When we use a 3 point starter
it slowly induces the back emf in motor so that the voltage
difference is less and rate of current flow is less, so the
motor doesnt get spoiled
