Abstract
Embodiments are directed to commanding, by a controller, a step in connection with a stepper motor. Further, embodiments include discharging a current in a coil of the stepper motor by transferring the current to a capacitor coupled to the coil responsive to the commanded step and driving a current in the coil. The driving of the current in the coil includes using charge stored on the capacitor during the discharging of the current in the coil.
