タ駆動回路。 A stepping motor drive in which an excitation signal formed based on a drive pulse is sequentially supplied to the other end of each phase winding to which a voltage higher than the rated voltage is applied to one end to excite the winding. In the circuit, one or more voltage sources supplying a voltage equal to or higher than the rated voltage to one end of the winding, one or more switching means connected between the voltage source and one end of the winding; one or more timer means triggered by a drive pulse to turn on the switching means for a predetermined period of time, and stepwise increasing the excitation voltage from the start to the end of excitation during the winding excitation period. A stepping motor drive circuit characterized in that:
