I've got a 12V, 2 Ohm/winding rated motor and I'm trying to figure out how much current it'll take. From Ohm's law 12/2 = 6A - and thats a lot! Is this much current needed to drive the motor? Can I use a lower amount of current? If so, how do I limit it? I don't have the datasheet for the motor. It does have a model number, but a google search did not reveal anything. Its a bipolar motor - only guessing because its got 4 wires coming out of it.
