を特徴とするステツプモータの駆動回路。 It has a distribution circuit that generates a signal for determining the order of excitation based on clock pulses from a clock generation circuit, and an excitation circuit that operates to flow a necessary current through the step motor windings based on the signal from the distribution circuit. In a step motor drive circuit, during forward rotation, the excitation phase is switched at a desired clock cycle according to the winding excitation order, and during reverse rotation, the circuit responds electrically, but the step motor rotor does not respond mechanically. The switching between forward and reverse rotation is performed by connecting a control means to the clock generation circuit which performs excitation by switching to the excitation phase one step earlier using a high-speed clock that has the same winding excitation order as during forward rotation. Step motor drive circuit.
