Star Delta Motor Connection Circuit Diagram. But high load 3 phase motor we use the star delta starter for motor control. Then a thermal overload relay is connected for the protection purpose.
Power control wiring diagram of star delta starter. Star delta starter power circuit diagram. Star delta starter wiring diagram this post is about the main wiring connection of three phase motor with star delta starter and control wiring diagram of star delta starter.
You can see in the below figure i have shown the star delta starter connection with a three phase motor.
First a main switch or mcb or mccb is connected to give the power supply to the circuit. For three phase motor we use the direct online starter but mostly for small three phase motor. 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. But high load 3 phase motor we use the star delta starter for motor control.
