    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.

     Induction Motor Wye Connection and Delta Connection

    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.

    Open the junction box of 1 phase induction motor

    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.
