Answer Posted / cool
Whenever you start a big heavy electric motor, you need to
start it slowly to prevent the rotor overheating and
drawing an enormous current. When the windings of a 3-phase
motor are connected in STAR the current is reduced to only
root three of the normal running current that is taken when
it is connected in DELTA.
