Abstract:
The purpose of the present invention is to provide an actuator that has a simple configuration and can stably achieve high output without the occurrence of magnetic saturation. This actuator has: a movable body provided with a cylindrical magnet section having alternately N-pole faces and S-pole faces on the peripheral surface surrounding a rotation shaft; and a fixed body provided with, pole tooth surfaces of the same number as the N-pole faces and the S-pole faces, and a coil that excites the pole tooth sections. The movable body has as a turning reference position a position at which the center of the pole tooth surfaces in the circumferential direction and the switching position of the pole faces of the magnet section face each other, and is held to the fixed body so as to be turnable back and forth around the rotation shaft in the circumferential direction.

Claim (Index 1):
An actuator comprising:\n a movable body including a rotation shaft, and a cylindrical magnet section including N-pole faces and S-pole faces circumferentially alternately on a surrounding circumferential surface around the rotation shaft; and a fixed body including a bearing that allows the rotation shaft to be inserted thereto, a number of pole teeth surfaces arranged so as to face the circumferential surface of the magnet section and circumferentially surrounding the bearing, the number of pole teeth surfaces being equal to a number of the N-pole faces and the S-pole faces, and a coil that upon supply of a current, excites the pole teeth surfaces so that the pole teeth surfaces have circumferentially alternately different polarities, wherein with a position at which a circumferential center of each pole teeth surface and a switching position between corresponding pole faces in the magnet face each other as a turning reference position, the movable body is held by the fixed body in such a manner that the movable body can turn circumferentially back and forth around the rotation shaft, and the bearing is a magnetic body.
