Motor Running Backwards

I had a motor die on me recently on a cissell air former. I took note of all the wires and changed out the motor. When i reassembled it the motor started spinning in the opposite direction. I dont know much about this kind of electrical stuff and dont want to short anything. Im hoping someone could push me in the right direction on how to fix this. I took photos if it helps. I appreciate any help/ feedback you guys have for me.

@boomx2brian,

Not looking at any links, but it sounds like a three phase motor. If so, reverse any two incoming leads and it will run in the opposite direction.

@boomx2brian,

I can't see all the motor leads but it looks like a single-phase motor. I can see the yellow T4 and the Red T5 and a black wire which are internal to the motor. I think your motor is running counter clockwise now. To reverse on a single-phase motor you would reverse leads T5 and T8. I am surprised your motor nameplate does not show that information. T8 should be the black wire.

@bahtah,

It is definitely a single-phase motor. Bahtah is right to swap the T5 and T8 leads.

Incidentally, nameplates will show wiring diagrams on three phase motors for variable voltages. On single phase motors, the diagram is usually found on the inside cover of the termination box on the motor (pothead)
