Driving device for a stepping motor

Image Number 7 for United States Patent #4959601.

In a driving circuit for a stepping motor in which a phase current corresponding to a predetermined reference voltage is generated when an excitation signal for each phase of the stepping motor is being produced and a coil of the corresponding phase is excited by the phase current, the supply time of the phase current is controlled by the pulse signal of a pulse generator for varying the pulse width, thereby improving the rising state of the phase current.
