Abstract

PURPOSE:To conduct both stopping operating at the time of one-phase excitation and the time of two-phase excitation under the best condition by making the pulse width of excitation overlapped at the time of one-phase excitation and the time of two-phase excitation differ. CONSTITUTION:The output of a multivibrator 10 is at on only for a fixed time after a point of time when the revolution of the stepping motor must be completed, and the output of an oscillator circuit 7 is sent out through an AND gate 8a only for the period, applied to two pulse generating circuits 11, 12 and each converted into two pulses having different pulse width. The output of the pulse generating circuit 11 or 12 is selected by means of a selects circuit SEL in response to the output of an excitation phase changeover circuit 6, and control signals controlling exciting currents are outputted through an AND gate 8b.
