摘要： There is provided a hybrid stepping motor comprising the following: a first rotor yoke and a second rotor yoke, each of the rotor yokes having a plurality of rotor teeth on a periphery thereof; a rotating shaft located between the first and second rotor yokes and supporting the first and second rotor yokes on a same axis, the rotating shaft including at least one permanent magnet magnetized in a direction of the axis; and a plurality of stator yokes, each of the stator yokes having a core portion, a coil wound around the core portion, and a plurality of stator teeth extending parallel to the axis from opposed end portions of the core portion, the stator yokes being disposed at regular intervals around the rotating shaft so that a constant air gap is maintained between radially inward surfaces of the stator teeth and radial end surfaces of the rotor teeth. A positive current is applied to the opposed and paired coils of said coils and a negative current is applied to the rest coils of said coils. The positive current and the negative current are applied at the same time and magnitude.
