I have a winch that was salvaged from a truck mounted crane. I bought it mainly because it was advertised as being 115 volt (plus, it looked pretty stout and the price was right).
The motor data plate says 115 volt, DC/60 cycle. It seems to operate just fine on standard house current (17 amps at full load). It has a NEMA 10-20 inlet that has the centerline blade wired as ground.
I'm sure it will be nice having an A.C. winch around the shop, but it sure would be handy if I could use this same winch on the road using DC power, but I am unfamiliar with "universal" motors.
What is the rule for DC voltage operation of universal motors? How low can you go?
The motor plate says 115.
