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
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

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.
