Here the circuit diagram of star delta starter explained in detailhere you will learn the connection of star delta starter with three phase motorthe power circuit diagram and control circuit diagram of an automatic star delta starter are explained belowlets understand the star delta starter diagram. A 8 pin timer are used.
Star Delta Starter Y D Starter Power Control And Wiring
Star delta starter control circuit diagram. In the diagram of power circuit of star delta starter u2 and v2 of 3 phase motor should be connect to 4 and 6 respectively instead of u2 and v2 are connected to 6 and 4 of delta contector km2. A star delta starter is a type of reduced voltage starterwe use it to reduce the starting current of the motor without using any external device or apparatus. In control wiring diagram all magnetic contactors coils are rated 220 vac. This is a big advantage of a star delta starter as it typically has around 13 of the inrush current compared to a dol starter. In the above star delta starter control circuit wiring diagram with timer and normally close push buttonnormally open push button switch. Star delta starter control circuit diagram.
The on delay timer diagram is also shown in the diagram. There is minor correction is require to change printed in boxes sequence of 3 phase wires from w2 v2 u2 to w2 u2 v2 to get delta connection properly. In this tutorial we will show the star delta y δ 3 phase induction ac motor starting method by automatic star delta starter with timer with schematic power control and wiring diagram as well as how star delta starter works and their applications with advantages and disadvantages.
