A Puzzle To Me, How to Reverse This Motor

[OverkillYJ]

So I have this old motor. If I am facing the side the pulley is on, it spins clockwise. Looks to me like it is wired for counter clockwise. So I guess I am looking at it from the wrong side. Problem I have is that I need it to spin the other way, and there is no diagram for that. Reversing the wires did not work. I am obviously not an electrical expert. Any help would be appreciated. Thank you

Which wires did you reverse?

Also that NM-b (yellow Romex) is the wrong wire to feed a motor with. Not saying I haven't done it....

its not wired for CC. its wired for clockwise because red is on 2/4 and green is on 1/3. you need to reverse red and green

I have not reversed anything on this motor. It is the way I got it. It seems it is currently set for 115 CounterClockwise. I need to switch it back to clockwise, but there are no diagrams or anything for the way it would have originally been wired.

The way I read it, the white (line) is on the wrong lug. It should be on 1 not 3.

1 & 3 have a little bar connecting them, so do 2 & 4, so it dopes not matter if I connect to 1 or 3 with the white. It was wired there with the black hot wire, but I swapped them to see if the motor would reverse before posting here.

This is a continuous duty motor from an old bandsaw. Its 1/2HP and I plan to use it for my very large shop exhaust fan. I am going to take a larger motor I have and upgrade my bandsaw, just s soon as I can figure out this motor.

I can post more pics and model and stuff if it makes a difference.

In post #1 you said you reversed the wires? If that was referring to the black/white that won't do anything to change the motor direction.

Look at the wiring diagram again.

The diagram shows the configuration for counterclockwise; Red on 1, Green on 2.

The motor is wired Green on 1, Red on 2; currently set to clockwise per the diagram.

Just reverse the red/green on 1/2 if its going the wrong way for you.

Fun fact - some manufacturers specify CW/CCW from the shaft end, some from the *** end.

According to the Diagram, the little bars need to be moved ALONG with the wires. One drawing shows 2 bars, the other drawing shows 1 bar.

The bars change to set voltage 115 vs 230.

Don't touch the bars.

Swap red and green on the motor.

Leave everything else the way it is and tell us what happens

Thank you. Looks like I am rushing too much. I am gong to take a close look again, look at these comments, and I'll let you all know how it goes.

only if he wants to change the voltage from 120 to 240v... otherwise leave the bars alone and only swap red and green

Thank you, that worked.
