Strip the ends of all 6 windings from the 3 sets of coils. The wires need stripping so they can connect properly to the screw terminals.
Read the labels on the 6 windings. You will have A1, A2, A3, B1, B2 and B3. The numbers represent the separate phase windings and the letters represent the beginning and end of each winding.
Match the windings for the Star motor in this manner: B1 to B2 and B2 to B3. Then make the center of the Star by matching these windings: L1 to A1, L2 to A2 and L3 to A3.
Connect the Delta windings as B1 to A2, B2 to A3, B3 to A1. Then connect L1 to A1, L2 to A2 and L3 to A3.
Tighten the windings onto the labeled screw terminals with a screwdriver.
Things You Will Need
- Wire stripper
- Screwdriver set
- Other 3-phase motors label windings differently than the Star Delta. For example, the windings might have the labels 1A, 1B, 1C, 2A, 2B and 2C.
