ことを特徴とするモータ。Two coils arranged so that their axial directions extend parallel to each other, a plate-shaped movable permanent magnet arranged between the two coils and fixed to one end of a rotating arm, and a movable permanent magnet sandwiched between the two coils. It consists of two fixed permanent magnets that are arranged parallel to each other and extend in substantially the same direction as the axial direction of the coil, and the movable permanent magnet is moved to an intermediate position between the two fixed permanent magnets by the repulsive force between the two fixed permanent magnets. 1. A motor, characterized in that the movable permanent magnet is moved substantially along the axial direction of the coils by passing a current through the two coils.
