I have heard that plugging a motor into a UPS unit can fry the UPS. is this true, and if so why? my only thought would be overload or arcing in brushes. this makes me think a shaded pole motor would be fine. I was considering running a small harbor fright water pump of an old ups as an inverter connecting battery inputs to old truck battery. I think the pump only takes maybe a few amps so shouldn't overload.
I have plugged florescent lamps into ups before, and they work, but make unusual hum sound that you normally don't hear. is that ok to run fluorescents like that other than possibly less life from the lamp?
