UPS on DC controlled tables?

Has any one tried putting in a small computer UPS to feed the DC supply on a turntable? This probably? wouldn't be so great ahead of a AC synchronous motor because the "sine" wave out of most computer UPS's is a bit squashed or triangled - but if for instance the output of your external supply is 27VDC - the purity of the sine output isn't too important ?

Yup it's dirty - but it's voltage stable. Certainly wouldn't want to do this on anything I was listening thru - but on a DC controlled TT - all I want is stable speed -if I feed it a solid stable voltage on it's input - it should output a stable solid DC output - this isn't the end of potential speed instability - but would? eliminate one variable?
Or not?
