why neutral can not used in three phase motor connection?

Answer Posted / kalidass

No need to use neutral connection in three phase motor
connection.
1. If the motor conneciton is in Delta only three phase can
connect.
2. If the motor connection is in Star the star point
(shoted point ) act as a neutral. (krichaffs current law)
So no need to connect the neutral.
