ABSTRACT:
A pulse motor driving device for a pulse motor having a plurality of windings. A first plurality of switching elements is connected to a first pole of a D-C power supply and to a connecting means for providing a connection to the windings of the pulse motor and to a second plurality of switching elements. The second pole of the D-C power supply is connected to the second plurality of switching elements. A plurality of diodes is connected to the connection means and to one of the poles of the D-C power supply. A capacitor is connected between one of the plurality of switching means and the D-C power supply. A comparison signal generator can be connected to the first plurality of switching elements, a reference voltage generator can be connected to the comparison signal generator and current detectors can be connected between the second plurality of switching elements and the D-C power supply.
