Hello there. I am about to use a Universal Motor(a Mototr that can both operate in an AD or DC supply). However i am quite confused by its rating. It is rated at 120 Volts AC. But my supply or source is DC since i am going to use it outdoors. My question is:
Is it safe to use a supply of 120dc?
If not which of these supply can i use?(all in dc)

12 0r 48 volts?
what would be the ideal dc source of it?
will it be 120/sqrt of 2 v dc?


Oh Yeah!
