ABSTRACT:
The invention is for an improved method and apparatus of driving a stepper motor with multiple voltages. A first voltage is applied to the step motor winding for a driving phase, and a second higher voltage is applied to the same motor winding during the same driving phase just prior to and substantially until the time that the winding is de-energized.
