How to Change Induction Motor Wye Connection to Delta Connection?

Induction motor refers to a motor that relies on electromagnetic induction between the stator and the rotor to induce current in the rotor to realize electromechanical energy conversion. Three-phase asynchronous motors generally have two wiring structures, WYE (Y) and Delta (△). When the Y-type access voltage is 380V, we can change it to △ type 220V.

Step 1:

• Open the junction box of this three-phase induction motor.
• ATO small power three-phase induction motor defaults to 380VAC Y-shaped structure.
• U2, V2, W2 are connected together.

Step 2:

1. Connect L1, L2, L3 with line voltage of 380V to U1, V1, W1, and the induction motor can run normally.
2. Delta (△) connects U1 and W1, U2 and V1, W1 and V2, respectively.
3. At this time, the rated voltage of the motor becomes three-phase 220VAC with the motor power unchanged.
4. The motor can be operated normally by connecting the three-phase 220V voltage to their junction.
