Need help with gear motor please
 

I have a Bodine gear motor that seems to be not working properly and I need to get it working if possible.
The motor is a 115v ac motor with a 90:1 gear reduction that should spin at 19 rpm (see link to motor below). When I got the motor (used) it was wired up to a toggle switch and a standard 3 prong electrical plug. However when plugged in and turned on it seems to only spin at about 4 1/4 rpm not the 19 rpm its rate for. Bodines website states that it should have a 4 MFD capacitor for it to run properly and this motor does not have the capacitor installed, could that be the problem? Or perhaps its wired incorrectly, there seems to be two sets of wires that go into the motor. Can someone possibly suggest something to look into, I have emailed Bodine, but got no response.

Here is the link to the motor:

there is a connection .pdf on the page you linked to, have you compared that to your wiring?

the lack of a capacitor shouldn't affect rpm

Are you in the USA, or somewhere else? Some motors tend to run much better at their intended frequency. In the USA, that is 60Hz, in the UK (IIRC), that's 50Hz.

IIRC, the capacitor is used for phase-shifting a little for easier starting (less current draw).

Yes I just noticed that as well, I must have had a brain fart. I am going to double check the wiring.



I am in Canada, there should be no power issues, im gonna double check the wirirng. Failing that what could the problem be, a shorted winding in the motor itself?

OK update here guys, the motor is wired to exactly what the diagram on the website shows. We check the wires coming from the motor and they have 0.5 ohms resistance and .8 ohms. The motor appears to be a brushless motor not a brushed motor I was incorrect on that. Any sugestions on what the problem could be?
