Post Subject: The “critical” motors for heavy belt turntablesPosted by Romy the Cat on: 3/28/2008

That is a whole another subject all together. I truly have no strong opinion on the subject but I do hear a lot of talking noise about the “quality” of motors for heavy belt driver turntables. My idea is that with a sufficiently heavy platter and proper tension of belt the influence of motor should not be issues for sound. Some people disagree and invest a lot of efforts, or at least talk into the motors. Go figure….

AC motors, DC motors, synchronous, asynchronous, brushed, brushless, big and powerful motors, under-powered motors, and motors with heavy flywheel… whatever people use. A friend of my a few years ago wanted to manufacture extremely advanced TT and he invested months of searching and huge financial efforts into founding of a “perfect motor” for TT. He calmed that it is virtually imposable to found a “right” motor for TT. Eventually he found some in Austria I believe some old new stock motors that he claimed “are the only one type of TT he have seen that could do the job”.  I have no idea what his problems with motor were, as well I am not exactly compostable with his technical justification but he did invested a LOT into the notions of “perfects” TT motor.

Interesting that I have purchased from him one of those outragesly expensive “unique and perfect” TT motor, more expensive then the cost of some turntables in many hi-fi installations. I made that “unique” motor to drive my Micro 8000 TT and… I heard nothing different. There was literally no impact if it was a different motor, so the “unique” motor is sitting in my storage….

I think that all fantasies about motors in case of use of heavy TT are not warranted...
