    Abstract: PROBLEM TO BE SOLVED: To suppress a phase current generated in winding of a stator over a full speed range of motor when driving a stepper motor in a voltage mode. SOLUTION: A method of driving a stepper motor in feed-forward voltage mode includes (A) a step of setting the amplitude of a sinusoidal phase voltage of the stepper motor to a predetermined value to rotate the stepper motor at a desired speed. The predetermined value is the sum of a back-electromotive force (BEMF) estimated via a function of the desired speed and a product of a desired amplitude of a phase current (Iphase) and an estimated absolute value of the impedance of the stepper motor.
