Japan, Feb. 27 -- MITSUMI ELECTRIC CO LTD has got intellectual property rights for 'ROTARY RECIPROCATING ACTUATOR.' Other related details are as follows:
Application Number: JP,2022-118083
Category (FI): G02B26/10,104,H02K33/16@B
Stage: PROBLEM TO BE SOLVED: To perform a drive with high rotational accuracy, low friction, and high reliability while improving the rigidity of a shaft.SOLUTION: An actuator comprises: a movable body that has a shaft part in which a magnet is fixed to an outer periphery and can reciprocatingly rotate around a shaft; a base part that has a pair of wall parts for rotatably supporting the shaft part through a bearing; a core body that has a plurality of magnetic poles facing an outer periphery of the magnet so as to sandwich the magnet; a core assembly that has a coil body wound around the core body for reciprocatingly rotating the movable body by energization to generate a magnetic flux that interacts with the magnet and a magnet position holding part for regulating a reference position of the reciprocating rotation by generating a magnetic attraction force between the magnet and itself; and a pre-pressure applying part that is out-fitted to the shaft part and applies a pre-pressure to the bearing.SELECTED DRAWING: Figure 2 (Grant)
