wrong run direction on 3 phase pump motor

wrong run direction on 3 phase pump motor

wrong run direction on 3 phase pump motor

(OP)
I connected a 3 phase motor of a centrifugal pump (0.75 kW)
After connection it turned the wrong way round.

My connection is the following

 W2  ----- U2 ----- V2

 U1  ----- V1 ----- W1
 |          |       |
 R          S       T


Which cables do I need to change in order to change the turning direction of the motor?

Do I have to switch R with S or T with S??

RE: wrong run direction on 3 phase pump motor

Hi.
You can swap R with S or R with T or S with T.
Isn't important. In all cases you will have reverse rotate of motor. But important put labeles accordantly
Regards.

Hello themroc

On a three phase motor, if connected and it runs opposite of the direction you want it to turn just swap any two leads and it will turn the other way.

RE: wrong run direction on 3 phase pump motor

Any two leads but NOT the earth lead!
