Starting an induction motor the motor is started in the Wye configuration ref fig 1 Once the motor has reached approximately 80 speed the motor is then connected in a delta configuration. Timer that switches the star and delta contactors. Star delta timer 1T2.
Star delta motor connection diagram electrical. From a circuit breaker in the MCC we have one set of 40 cables going to to the main contactor in the compressor and the other set of cables going from the breaker and landing on the delta contactor of the compressor. If you press start buttonwye contactor energize same time with omron timer on delay after 5 seconds wye de energi.
This can reduce cost in many applications. Leading The Industry in Product Availability Speed of Service Responsiveness and More. Wye Delta Starter ref fig 2 This is considered an electrical mechanical reduced voltage starter.
They are used in an attempt to reduce the start current applied to the motor during start as a means of reducing the disturbances and interference on the electrical supply. An advantage of the Wye connection is that it can provide multiple voltages without the need for additional transformers. Wye Start Delta Run.
