ELECTRICAL MOTOR CONNECTION

ELECTRICAL MOTOR CONNECTION:


Change Rotation in Clockwise Direction
No Present Motor Connection: Change Direction in Clockwise
1 R Phase Connected to U1 W2 R Phase Connected to U1 V2
Y Phase Connected to V1 U2 Y Phase Connected to V1 W2
B Phase Connected to W1 V2 B Phase Connected to W1 U2

2 R Phase Connected to W1 V2 R Phase Connected to W1 U2
Y Phase Connected to U1 W2 Y Phase Connected to U1 V2
B Phase Connected to V1 U2 B Phase Connected to V1 W2

3 R Phase Connected to V1 U2 R Phase Connected to V1 W2
Y Phase Connected to W1 V2 Y Phase Connected to W1 U2
B Phase Connected to U1 W2 B Phase Connected to U1 V2
Change Rotation in Anticlockwise Direction
No Present Motor Connection: Change Direction in Anticlockwise
1 R Phase Connected to U1 V2 R Phase Connected to U1 W2
Y Phase Connected to W1 U2 Y Phase Connected to W1 V2
B Phase Connected to V1 W2 B Phase Connected to V1 U2

2 R Phase Connected to W1 U2 R Phase Connected to W1 V2
Y Phase Connected to V1 W2 Y Phase Connected to V1 U2
B Phase Connected to U1 V2 B Phase Connected to U1 W2

3 R Phase Connected to V1 W2 R Phase Connected to V1 U2
Y Phase Connected to U1 V2 Y Phase Connected to U1 W2
B Phase Connected to W1 U2 B Phase Connected to W1 V2
Thumb Rule :
Check Phase Winding Starting Phase and Connected ending Connection of That Phase winding to the one Phase after the Phase where Phase winding Starting lead is connected. (Ex If U1 is connected to R Phase than Connect U2 to B Phase, If V1 is connected to Y Phase than V2 should be connected to R Phase)
