摘要
A method of driving a stepper motor in feed-forward voltage mode, comprises the step of setting, for a desired speed to be impressed to the stepper motor, the amplitude of a sinusoidal phase voltage of the stepper motor equal to the sum of the expected back-electromotive force (BEMF) amplitude estimated in function of the desired speed, and the product between a desired amplitude of a phase current (Iphase) and an estimated absolute value of the motor impedance.;A relative system is also disclosed.
