Abstract
A compact stepping motor is equipped with at least four stator plates positioned in parallel with each other, a rotor with a rotary axis perpendicular to the stator plates, and at least two energizing coils each positioned between each two of the stator plates. The rotor is positioned out of the energizing coils. The center axes of the coils and the rotary axis of the rotor are in parallel with each other. One coil is positioned between one pair of stator plates and one coil is positioned between the other pair of stator plates and share a common center axis. Circumferentially arranged stator poles extend from each stator plate perpendicularly to the each stator plate so as to surround the rotor at a specified distance.
