WTB: Numechron "TV Clock" 1 RPM CCW motor

I recently picked up one of those Pennwood Numechron clocks with a stalled motor.
I popped the back off and coaxed some life out of it, but it's off balance, noisy, and stalls if you look at it cross-eyed.
Anyone have a similar donor motor? I think Syncron makes something compatible. It needs to be 117 VAC, 1RPM and CCW as you look the the shaft.

Here are some pics.



Most I've seen have red, green and blue digits.
This must be the B&W model


Thanks!
Bob

Check with Timesavers, they have a couple of different 1 rpm motors in their catalog. You will have to do some adapting

Never seen one but it's pretty awesome imo... Reminds me of a (?) Sears nixie tube clock with a motor-run AC clock in it ... wish I had it but it 'got tossed' in a house cleanout when I was little....

Thanks. Yes, they do have some that might work. I also found this Cramer motor from Digi-Key that looks like a good fit: http://parts.digikey.com/1/parts/678...vac-61069.html

Both a bit pricey considering what I paid for the clock though I guess these motors aren't as common as they used to be.
I probably tossed a few myself over the years without thinking about it.

Have you seen the descriptions of getting the motors to run again? I may be thinking of noisy motors versus one that does not run at all, though.

Yes, I saw the thread on noisy clock motors.

I popped off the back and could barely rotate the flywheel. A few squirts of WD40 and lots of manual turning free it up enough to run under it's own power. But like I said it ends to stall and is kinda noisy. I'll try some 3-in-1 in the gearbox and let it run a while longer. Maybe it'll get better. Even so, I wouldn't mind putting in a newer motor. I think this is a pretty early model since it has black digits instead of the common red, green & blue models. Maybe early 50s
