PURPOSE:To reduce the error of the same stopping position generated when a pulse motor is driven to be reciprocated by supplying a current to an auxiliary winding to remove a remaining magnetism. CONSTITUTION:First and second auxiliary windings 1a, 2a are respectively provided at first and second exciting main windings 1, 2. When exciting currents flowing through the windings 1, 2 become zero, it so controls as to supply exciting currents having reverse polarity to that of the exciting currents flowing to the windings 1, 2 immediately before to the windings 1a, 2a disposed in the same cores C, D as those of the windings 1, 2 to remove the remaining magnetism by the exciting currents. |
