摘要： 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.

摘要： An actuator includes: a movable body including a single-pole magnetized single pole magnet; and a plurality of electromagnets each having a magnetic core portion and a coil portion for exciting the core portion. The actuator has: a fixed body on which three or more magnetic poles of the electromagnets are disposed at positions orthogonal to the magnetization direction of the single-pole magnet; and an elastic body bridged between the movable body and the fixed body and elastically deforming when current is supplied to the coil portion, thereby supporting the movable body so as to be movable in the magnetization direction of the single-pole magnet and the two-degree-of-freedom direction. The elastic body is attached to the movable body so that the movable center of the movable body matches the substantial center of the generated magnetic torque of the movable body.

摘要： An operation input device includes a coil, an operation part configured to be displaced in an axial direction of the coil by the action of an operation input, a core whose positional relationship with the coil is changed by the displacement of the operation part, a yoke placed outside the coil, and a magnet configured to generate a magnetic flux that flows through the core and the yoke. The coil is configured to output a signal corresponding to the amount of the displacement of the operation part. The operation part is caused to move by an electric current flowing through the coil and the magnetic flux of the magnet.

摘要： Disclosed is an actuator that generates the reciprocating rotational motion of an electric toothbrush or similar without employing a drive transmission mechanism as a separate entity from a drive source. An actuator (100) includes a fixed body (110) comprising an outer yoke (140) having inner wall planes that respectively oppose the magnetic pole planes of unlike poles of a magnet (150) with a predetermined gap therebetween. A coil (122) is arranged to encircle the magnet (150) between the magnetic pole planes of the unlike poles of the magnet (150) and the inner wall planes of the outer yoke (140) that respectively oppose the magnetic pole planes of the unlike poles, and this coil (122) is movably supported as a movable body (120) by way of an elastic member (130) fastened to the fixed body (110). The reciprocating rotational motion of the movable body (120) is afforded by the supply of an alternating current of a frequency approximately equivalent to the resonant frequency of the movable body (120) from an alternating current supply (180) to the coil (122).
