Star delta motor control wiring. Speed depends upon only supply frequency and no of pole in motor speed can not change due to voltage variation for ac induction motor star delta connection used for ac induction motor. But high load 3 phase motor we use the star delta starter for motor. 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. For three phase motor we use the direct online starter but mostly for small three phase motor. 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. 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.
