Star Delta Wiring Diagram Control Circuit. Star delta wiring diagram electrical engineering updates. When the motor gains speed, the star contactor is opened while delta contactor is closed turning the motor windings into delta configuration.
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. Star delta starter control circuit diagram is today's topic. In my last post, i share a star delta starter wiring diagram 3 phase motor connection.
This energized star contactor coil and motor get connected in star.
This type of starting is suitable for small motors below 5 hp (3.75 kw). This energized star contactor coil and motor get connected in star. The contactors are controlled by using plc. When the start push button is switch on in the external input terminal of the plc, its corresponding input terminal address x0 activates.
