Star Delta phase and terminals

RED PHASE : U1 and W2 YELLOW PHASE : U2 and V1 BLUE PHASE : V2 and W1 So..from this formula,we must wiring the motor follow the phase color code.

See my example below :



We can refer the complete wiring for star delta starter diagram below.If you want change their rotation for clock-wise or anti clock-wise,you need change two of phase ( RED or BLUE) at delta contactor.I share the technique how to change rotation in my next post.

If you want motor rotation for clock-wise,the phase colors are RED,YELLOW,BLUE.But if you want anti clock-wise rotation,the phase colors are BLUE,YELLOW,RED.For star delta control wiring diagram,please refer to my post about star delta diagram control
