摘要： A disk player having a self-compensating dynamic balancer (400) which can limit internal vibrations generated by an eccentric center of gravity of a disk, and a turntable (200), a clamper (300) and a spindle motor (100) which incorporate the self-compensating dynamic balancer (400), are disclosed. The self-compensating dynamic balancer (400) includes at least one race (450) which is integrally formed with members (100,200,300) of the disk player, and a mobile unit including a plurality of rigid bodies (430) and/or a fluid (440) is located in the race (450) to be capable of moving, and a cover member (413) to cover an opening of the race. Thus, internal vibrations occurring due to an eccentric center of gravity of a disk (1) can be effectively limited by the self-compensating dynamic balancer (400) in which the mobile unit (420) is to move away from the center of orbital rotation by a centrifugal force during rotation thereof.

摘要： A P.M. d.c. motor (10) in which the permanent magnets (32, 34) thereof are provided as thin arcuate segments of predetermined length which rotate about a circular locus of core component (14, 16) defining poles. The paired permanent magnets are configured to slightly straddle the end surfaces of the core components as they pass thereover to effect a shear form of magnetic interaction with flux interaction regions or surfaces of the laminar core components. This serves to substantially minimize axially directed magnetic attractive forces including any time varying axial force terms which may be developed in consequence of commutation. Further a localize rotor balancing is achieved. A highly efficient core structure formed as a core base having outwardly extending legs which are bent perpendicularly upward to form upstanding core components is provided. Additionally, an aerodynamic seal is developed at the periphery of the rotor stator combination to provide for the isolation of any contaminants.

摘要： A self-compensating dynamic balancer is coupled to a rotating body to restrict internal vibrations generated due to eccentric mass of the rotating body. The balancer includes a main body (60) having a circular race (61) formed therein and being concentric with a rotation shaft (51) of the rotating body, a plurality of moving members (70) disposed in the race capable of moving, and a cover member (80) coupled to the main body to cover the race. An outer wall (61b) of the race is formed to guide movements of the moving members (70) such that each of the moving members can contact the outer wall of the race during the rotation of the main body. Also, at least one protrusion (81,65) is formed on the surface of the cover member (80) facing the moving members and/or the bottom (61c) of the race, to guide movements of the moving members (70) by selectively contacting the moving members, when the rotating body rotates by being installed vertically.
