Rewiring motor from 220v to 110v

[arjog]

Sorry if this is a little off topic, couldn't figure out where to best put it.

I'm new here. I've been lurking for a couple months, but first post I think. Anyway, I have an old craftsman belt sander that I am refurbing and picked up a cheap 1/2 HP motor to drive it. Unfortunatley, the motor was wired up to run on 220 (but says it can run on 110) and is missing the plate with the wiring diagram. I need to figure our how to switch it over. Anyone have any ideas? Attached is a pic of the current wiring set up. It definitely runs on 220 currently, (and runs very slowly on 110). I have labeled the terminals as they are labeled on the motor, as the labels didn't show up very well in the pics. The black and white wires (labeled black and white) go to the plug. The rest of the wires are all internal. Any help? Thanks.

BTW, I've sanded and painted the motor since the pics were taken, so don't worry about the rust.

arjog,
My first thought would be to move the black wire from #2 and the red from #4 to the #3 terminal.

It would, of course, be risky to do this without knowing for sure. Can you post any other info about the motor? Brand, model#, etc.....

Check over here: http://www.owwm.com/FAQ/

Towards the bottom is a section on motors and electricity. Also, with some more information they may be able to answer your question in the forums over there.

Thanks for the info guys. Here's a little more info on the motor. It's a 1/2 HP motor made by Century Electric Co. of Saint Louis, MO. I briefly googled the company and didn't find much, so I don't think they are still in business. I took a photo of the name plate, but you can't read the stamped info on it. I can go out to the garage and get more info in the morning if it would help.

I have an old Century dual voltage motor for my Air compressor. The tag on the outside says:

High voltage-

GREEN-------------------o Line

BLUE/BLACK/RED----------o

BROWN/YELLOW----------o Line

Low voltage-

BLACK/GREEN /BLUE---------o Line



RED/ BROWN/YELLOW--------o Line

reverse blue and yellow to reverse direction.

I did not have a chance to open the terminal box to see if there are similar numbered screws like yours. Not the same motor but hope this helps you figure it out.
