Hi all, I have an old Sessions electric mantel clock whose motor suddenly stopped running. I thought it could be due to gunk buildup within the movement or the motor itself. At first, I removed the shaft/arbor from the bronze bearing and cleaned everything with a pipe cleaner and some WD40. Plugged it back in, and still no luck. Then I took the motor apart as far as I could, which involved opening the case to the point that I could see the copper wire, etc. There appeared to be a thin (plastic?) ring that seemed to act as a spacer for the copper plates that interface with the motor body. That spacer basically crumbled as soon as I popped the case open. I wasn't able to identify any broken wires or failed electrical components otherwise. After reassembling, the motor still shows no signs of life. No humming, no movement, no apparent magnetic force. What are my options for reviving this thing? I hate the thought of putting a $10 plastic replacement movement in it. I'm hoping I can track down a replacement motor, if this one truly can't be salvaged. A few pics are attached, showing the motor, and the clock body.
