So I have a similar motor udz 112 g 63 82539
***The term ac power supply is a power cord that is not plugged in. Make all connections without power double check connections and secure with insulated tape before plugging anything into anything with voltage

So on mine Pin 2 go to left side windings and pin 3 the brush on right side and 7 goes to right side windings and 8 brush on left side. 1 and 6 go to tach 4 and 9 to thermal switch and 10 goes somewhere inside and I don't care what it's for. So I ignored pins 10 I don't know what it goes to maybe ground, 1 and 2 because I don't care about a tach, 4 and 9 because if it gets too hot and has a meltdown I can throw it away and get another one for free. If you connect 1 brush to your ac power source and the winding on the opposite side of motor to the power source( doesn't matter which is main(hot) or neutral because it's ac)
Then jump the other winding to the other brush it should work. I'd recommend hooking everything up before plugging it in but that's your choice. If you care about this motor don't run it very long with this config just test to see if it works. For long term use disconnect the brush that is hooked up to ac power supply now connect that ac power supply to 1 side of the thermal switch and the other side of the thermal switch to the brush that you just unplugged. This will stop powering the motor when it gets to hot, if the thermal switch is working correctly. This should work on most single phase induction motors.

I found a Youtube video featuring your motor, or at least the phrase "FHP UOZ 112 G55" is in the title, and the teaser image kind of looks like the picture you attached to this topic. I have not watched this video.


I am guessing your motor is a universal motor.


That kind of motor has a stator winding, a rotor winding connected via brushes, and uh... what else?

This instructable,


shows a hand drawn diagram, with two pins for a "tacho coil."

I am guessing that does not refer to Mexican food (spelled "taco"), but rather a kind of "tachometer" sensor, for measuring angular speed.

Do we have enough pins yet? You said your motor has 7 pins?

I suppose success depends on correctly discovering which pins go to what things.

Perhaps by looking at a whole bunch of different, "washing machine motor wiring diagram"


you might discover which one is specific, or approximate, your motor.
