PROBLEM TO BE SOLVED: To materialize a drive circuit which controls the application of a large current under a small induced voltage by making each piece of three-phase coils independent of each other without being connected with each other, and connecting the current application control circuits of single-phase full waves each independent of a power source to independent three-phase coils, in a drive circuit for a three-phase stepping motor. SOLUTION: In this drive circuit for a stepping motor, each piece of three-phase coils is independent of each other without being connected with each other, and current application control circuits each independent of a power source are connected with independent three-phase coils so that a large current can flow on a low induced voltage of 120°in phase angle.
