リアクチユエータのステータ。[Claims for Utility Model Registration] (1) Supply of excitation current from an intermediate terminal opening into the interior of a cup-shaped stator in which cup-shaped magnetic members of the same shape with a plurality of pole teeth formed on the circumference are meshed and opposed to each other. A rotary actuator that houses a coil that generates a magnetic pole in the pole teeth in response to a magnetic field, and that rotates a rotor magnet provided on the inner circumference of the cup-shaped stator by an arbitrary angle when an excitation current is applied to the coil. In the rotor magnet, when magnetic poles are generated in the pole teeth, the distance between opposing end faces of adjacent different poles is minimized so that the shape of each end face coincides with the axial direction of the rotor magnet, and A stator for a rotary actuator, characterized in that pole teeth are formed by making a distance between opposing end faces larger than the distance between opposite end faces. (2) A stator for a rotary actuator according to claim (1) of the utility model registration, characterized in that the pole teeth have a tapered tip shape.
