What motor?

[bangster]

This here is a 1050-020 electric hybrid.

Its ST number is A502-000

I need to know (a) what motor it takes, and (b) where to look for one.
Thanks in advance for your help

Doesn't appear like they are easily identifiable. Sure there would be a motor that would work, you may have seen the below thread, any clues to be gleaned from it?

Tnx for link, Shim. That looks like exactly the item I need. Now to track one down.

Indeed, I've found out the motor it takes. Now to find one that works.

See if these people have anything that might be adaptable. The direction and rpm would be critical, but they might work.

Timesavers had a motor like you need, but it seems to have been discontinued. I purchased and used one once a couple of years ago, and there was a good deal of work involved to get it to fit.

M5A 'bottlecap'. 3.6 RPM, pretty easy to rebuild, closing the aluminum case after opening isn't so easy. Fortunately the field and coil assy holds the case closed tightly against the plate when assembled. I glue the alloy cap to the capsule base lightly first to contain the lubrication. I retrofitted a Telechron H type long ago with the M5A pinion as a experiment, and it worked fine. I guessed the torque requirements of driving this movement over years would shorten the life of a H type, but never encountered that in use.
