Abstract:The present invention relates to a drive circuit for a stepping motor. The drive circuit provides a low voltage to the coils of the stepping motor in the steady state, and a high voltage to the coils when changing state. As a result, the state changes rapidly and the stepping motor is driven efficiently. The high voltage is derived from the energy which was stored in the winding of the stepping motor before the switching occurred by transferring that energy to a capacitor which achieves a charge potential that is greater than the potential of the power supply voltage.
