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, a voltage higher than the rated voltage is directly supplied to one end of the winding, and a timer means is provided for outputting a signal when the drive pulse is not supplied for a set time or more, and this output signal causes the A stepping motor drive circuit characterized by turning off an excitation signal.
