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. Asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding. Coba perhatikan lagi gambar hubung star delta yang telah saya perjelas dari gambar artikel sebelumnya di bawah ini.
In this tutorial we will show the star delta y d 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. For three phase motor we use the direct online starter but mostly for small three phase motor. A contactor is a heavy-duty relay with the high current rating used for power up the electrical motorThe current rating for contactor varies from 10 amps to several hundred amps.
I already explain how to connect power supply for star delta motorplease refer the wiring diagram at the bottom post. Wiring Diagram Star Delta. So our main target is at the starting time the motor windings should be connected in Star and then it should be connected in Delta.
The initial connection should be in the star pattern that results in a reduction of the line voltage by a factor of 13 577 to the motor and the current is reduced to 13 of the current at full voltage but the starting torque is also reduced 13 to. Main contactor star contactor and delta contactor. But high load 3 phase motor we use the star delta starter for motor control.
