Can't find any sites offering the turntable motor for a CTAL30
There are, however, a lot of places offering the little plastic coupler between motor and turntable. If that's broken it may explain the lack of drive.
I think you should be able to pull the coupler off. It'll probably be really easy if it's broken.
You might even just be able to push a replacement straight on.
