The control circuit uses to control the starter circuit such as on off and tripping operations. The power circuit uses to create contact between the motor and three phase power supply. Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse.
Now in the below diagrams three phase motor will rotate in two directions viz forward and reverse.
Power and control circuit star delta starter control circuit diagram star delta control circuit s. Three phase motor connection star delta y δ reverse and forward with timer power control diagram as we have already shared the starting method of three phase motor by star delta starter with timer circuit power and control circuits. Automatic star delta starter with timer for 3 phase ac motors. A dual starter connects the motor terminals directly to the power supply hence the motor is subjected to the full voltage of the power supply consequently high starting current flows through the motor.
