Reverse an electric motor

[Mike BishopParticipant @mikebishop93339]

I have recently aquired a fractional hp single phase motor for my lathe and need to reverse the direction of rotation. What is the correct way? I dont want to cross belts.

Apologies if you’ve already checked this: some manufacturers fixed an instruction slip in the connection box lid.

The motor should have 4 wires comming out of the inards and into the terminal block. It will have 2 seperate windings which can be identified with a multimeter. With the meter on the ohms range you will get a reading between the 2 wires comming from each winding . You need to reverse the connections to one winding only.
