Origin Live told me that I may need to help the platter to get rotation started with my hand. If this turns out to be true, this is unacceptable. I was not thinking that my hand would be a crank for the turntable start procedure.
I’m the opposite. I always ’help’ my platter get started and up to speed. Otherwise, all the work is done by the belt and motor, or on a DD, by the motor. It causes belts to stretch, and motors to do far more work to overcome inertia, and the heavier the platter (and most think heavy is good) the more work is required. Once at speed, maintaining speed is much less stress on motor and belt. And I don’t think I’m being imposed upon: I’m helping.
Synchronous motors are DESIGNED to be constant speed based on supply FREQUENCY.
Supply frequency is not stable nor reliable. I filmed a documentary in a new power station. Everything was the latest tech. Very impressive — until I reached the frequency control room. The "high tech" controller was a guy at a big steering wheel (looked like the helm-wheel on a racing yacht) and staring at a huge meter. 50Hz was the target, and despite his efforts, the meter was always moving — 49Hz, 50Hz, 51Hz — and he would correct by turning the wheel. Sometimes it dipped to 48 or rose to 52. It AVERAGED 50Hz over 24 hours, but with many fluctuations. I hope, but don't know, it's been improved since then...
