特徴としたステッピングモータ駆動装置。In the current inflow path to each winding that constitutes the stepping motor, there is a switching element for determining whether or not current can flow into the winding based on a phase switching signal, and a switching element that turns on/off the current inflow to the winding. A resistor is inserted in series for extracting a detection voltage due to current flowing into the element and the winding, and an amplifier is connected to the output side of the amplifier for comparing the reference voltage from a reference voltage generation source and the detection voltage. In the constant current chopper type stepping motor drive circuit comprising a pulse width modulator for driving the switching element for turning on and off, the reference voltage generation source generates a reference voltage as a reference voltage from the reference voltage generation source. A plurality of resistors and a switching element for switching the connection state of the plurality of resistors to obtain a first reference voltage, a second reference voltage, and a third reference voltage corresponding to high, medium, and low levels, respectively. a winding current corresponding to at least low speed rotation of the stepping motor by a third reference voltage;
A stepping motor drive characterized in that depending on a first reference voltage, a winding current necessary to start high-speed rotation is supplied to the winding, and depending on the first reference voltage, a winding current sufficient to continue the high-speed rotation is supplied to the winding. Device.
