Hi there! I need some help in fixing or replacing a motor from a Transcriptor turntable I'm trying to restore. The motor itself is french-made, with the words "LIC. ATO CROUZET 831A BREVETE S.G.D.G.". The problem with the motor is that the windings are open, but they're all sealed in an opaque white plastic that appears to have been molded on. Alas, I cannot inspect them to check the location where the input wire is spliced onto the winding wire, which is where I suspect the break had occurred. Are there any suggestions for how to cut/melt/dissolve away the plastic at that site without damaging the delicate windings underneath?? Am I better off just scrapping the whole thing?? In that case, I will have to replace the motor. Any suggestions on where to find a compatible motor quickly and inexpensively? THis one is cylindrical, about an inch thick and just under two inches in diameter. It runs on 120VAC, and should turn (according to my calculations on motor and platter pulley size and platter rotation speed) at about 1800 RPM clockwise. It's brushless and has five poles on the rotor and five on the stator, but I'm not sure of how to relate that statistic to overall engine RPM's. (Help needed here, too.) Since it is going into a nice turntable, the motor should be quiet, smooth, and well-shielded. Any help would be sincerely appreciated. Please e-mail or post if you desire to enlighten the rest of us. Many thanks..

Am I better off just scrapping > Sounds to me that you'd be better off taking the thing down to an electrical repair shop or look up "Electric Motors" in the yellow pages and call a few of them who advertise rewinding services. That insulative goo was put there because their manufacturing process blew chunks. Forget getting it off with anything other than a severe thermonuclear attack. They'd be able to rewind another core or use that one after they've nuked it. Another option is to write off to the company in question (if they still ). There are many motors availble that I'm sure would fit into the housing and operate at the desired RPM. A look through some catalogs might help.
