Japan, Feb. 27 -- MITSUMI ELECTRIC CO LTD has got intellectual property rights for 'ROTATION RECIPROCATION DRIVE ACTUATOR.' Other related details are as follows:
Application Number: JP,2022-134985
Category (FI): G02B26/10,104@Z,H02K33/16@A,H02K33/16@B
Stage: PROBLEM TO BE SOLVED: To preferably drive a movable object with a high amplitude.SOLUTION: A rotation reciprocation drive actuator includes: a mobile body that includes a shaft part to which a mobile object is connected on one end part side and a magnet fixed to the shaft part on the other end part side, and is supported around an axis to be reciprocation rotatable; a base part that includes a pair of wall parts that rotatably supports the shaft part via a bearing on the one end part side, and is arranged so as to nip the mobile object; a core assembly having a core body that includes a plurality of magnetic poles opposite to an outer periphery of the magnet so as to nip the magnet, a coil body that is wound around the core body, and makes the mobile body rotate in reciprocation by generating a magnetic flux that mutually acts with the magnet by power conduction, and a magnet position holding part that regulates a reference position of the reciprocation rotation by generating a magnetic suction force between itself and the magnets, and is attached to the other wall part of the pair of wall parts; and a sensor substrate which is attached to one wall part of the pair of wall parts, to which a sensor for detecting a rotation angle of the shaft part is mounted, and in which the sensor is arranged from the one end part side to the one wall part toward the one wall part side.SELECTED DRAWING: Figure 2 (Grant)
