can three phase induction motor rotate with only 2 phases
connected
Answer Posted / bhasheer
only two phase will never create rmf in three phase motor... we need a capacitor to create three phase rmf. while using the capacitor the motor starts to rotate but the starting torque will reduces....
During the normal running condition of three phase motor, if one phase fails, the motor will run continuously when there is no load in the shaft.
At the same time if the motor is connected through the starter,the over load relay in the starter trips and the motor will stops....
