Motor Wiring Help

[PCMusicGuy]

I have what looks to be an older Bodine Electric Company 115V motor. On the plate I see 115V, 1.8A, continuous duty cycle, 1725 rpm, and type USI-34. There are 3 wires coming out the motor, two black and one green. There is nothing to distinguish the two black wires from one another. I got this from an yard sell and I just wanted to provide power to it to check if it still runs. Would would you recommend doing? I'd rather not pull it apart to see where the wires are attached if possible.

One black goes to the hot, the other to neutral. It does not matter which is which in this case. Green is ground obviously.

just check and make sure it's AC motor .... I have a 115V DC sitting right next to me . ha, and no, it's not from the Edison vs Westinghouse era.

If you are sure it is AC motor.... most likely it's whats mentioned black = hot, white=neutral green is ground.... test with ohm or continuity? Simple right...
green to motor housing... white to black check for ohms ...

Probably one of those prewire to certain rotation if it is AC with that 2 wires.

Ok. That is what I thinking. I'll check it out this week.

Let us know what you find out.

So I hooked up the black wires to line and neutral and the green wire to the ground and plugged it in; it started spinning and seems to work fine. I let it run for about 5 minutes and it was smooth and quiet the entire time.

I do have one question on it. When starting the shaft of the motor gets pulled into the chassis a bit, which I've seen with some older electric motors. Just how much movement is normal and what causes this? A worn bushing or retainer?

I really am not sure, I have seen the end play often myself.
I'm thinking I've seen about an 1/8" or so.
Is the motor turning the direction you need it to?

Cool little Amp draw meter you got your Whip plugged into......

The rotor wants to center itself in the magnetic field of the stator. If you don't want the motor shaft to move longitudinally, take it apart and put a wavy washer (Google it) on one end or the other. Or, if this movement doesn't cause a problem in operation, ignore it.

Thanks for the feedback. The movement doesn't cause me any problems. I actually do not yet have a use for the motor. It was attached to a box with an outlet and a switch and some extremely sketchy wiring. I found it rummaging through the stuff at an antiques fair in Round Top, TX last year. He was asking $20 and I got it for $10. I've thought of a few uses for it but haven't put any plans in motion so to speak.
