single phase..???

mhhh....

normally a single phase engine only uses 2 windings and a third which is only enabled on startup...

the 2nd winding uses an capacitor...tu generate an offset on the normal wave shape..

google is your friend i would say...

Tks

As you apply power, give it a helping hand in the right direction.
Alternatively try plugging it in to a neighbours supply. My old next door neighbour had a wood lathe that ran in opposite directions when plugged into his/my supply. weird but true.

If you take the cover off the motor, where the wire goes in, there is usually a connections diagram to wire it for CW or CCW rotation.
