ABSTRACT:
A driving circuit for a five-phase stepping motor includes five phase-windings each having a starting end and a terminating end in which each of the starting ends is successively connected to each of the terminating ends to form a ring, pairs of switching elements connected in series to each other and each pair of which includes a connection therebetween which is connected to each of junctions between the phase-windings and in which one of each pair of the switching elements is connected to the positive pole of a driving power source and the other of each pair of the switching elements is connected to the negative pole of the power source so that the switching elements are turned on and off to connect the junctions to the positive or negative pole of the power source or not to connect the junctions to any pole of the power source, and the junctions connected to the positive pole and the negative pole of the driving power source are changed when the stepping motor is driven so that various controls are attained.
