Delta Wye Motor Wiring - Wiringguides

Delta wye motor wiring is a method of connecting a three-phase motor to a three-phase power source. In a delta connection, the motor windings are connected in a triangle shape, while in a wye connection, the windings are connected in a Y shape. Delta wye motor wiring is used to change the voltage and current characteristics of a three-phase motor.

The main benefit of delta wye motor wiring is that it can be used to reduce the voltage applied to the motor. This can be useful in applications where the motor is required to operate at a lower speed. Delta wye motor wiring can also be used to increase the current applied to the motor, which can be useful in applications where the motor is required to generate more torque.

One of the key historical developments in delta wye motor wiring was the introduction of the autotransformer. Autotransformers are used to change the voltage applied to a motor without the need for a separate transformer. This makes delta wye motor wiring more compact and efficient.
