How to Change Rotation of Motor 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)

mr jignesh can 9 terminal motor runs on star delta starter
I’m trying to get a 400 v 3 phase motor to work on a table saw Feeder. It’s rated at 1 hp.
Found an old machine motor that’s rated at 400 v also & thought I’d try hooking up my shop (using a 3 phase motor) generated 220/208 v 3 phase. It runs other equipment fine. Hopefully it will run the 440 v motor. No matter if it’s less power that the 1 hp, less is ok. Any idea’s or suggestions there ?
