Abstract:
A method of driving a stepper motor in a feed-forward voltage mode may include for a desired speed for the stepper motor setting an amplitude of a sinusoidal phase voltage of the stepper motor to be equal to a sum of an expected back-electromotive force (BEMF) amplitude estimated as a function of the desired speed, and a product of a desired phase current amplitude and an estimated absolute value of an impedance of the stepper motor.
