Steppers get marked like other motors, but they aren't operated like other motors. Your motors, depending on size, might have two or three heavy coils in parallel. This drives the resistance down to 1 or 2 ohms. At 100% duty, this gives them a nameplate rating of 3 or 4 volts. But, in actual operation, you don't use 100% duty.
