  • Publication number: 20250067954
    Abstract: An optical member driving mechanism is provided. The optical member driving mechanism includes a first movable portion used for connecting an optical element, a fixed portion, a first driving assembly used for driving the first movable portion to rotate relative to the fixed portion, and a guiding assembly having a first intermediate element. The first movable portion is movable relative to the fixed portion. The guiding assembly is used for applying a first stabilized force to the first movable portion for making the first intermediate element be in contact with the first movable portion or the fixed portion. The first movable portion is rotatable relative to the fixed portion.

  • Patent number: 7382068
    Abstract: A spindle motor includes a stator structure and a rotor structure coupled to the stator structure. The stator structure has a stator base, a magnetic conductive structure surrounding the stator base, and a first buffer structure provided in the gap defined by the stator base and the magnetic conductive structure and in contact with both the stator base and the magnetic conductive structure. Furthermore, a second buffer structure and a third buffer structure are respectively provided between the stator base and the casing and between the stator base and the base plate.

  • Publication number: 20060083643
    Abstract: A pump includes a case, a base disposed in the case and a rotor. The rotor includes a magnetic extension portion which surrounds a yoke. The pump gains efficiency in view of the above without increasing volume. Furthermore, the pump includes a first magnet and a second magnet, positioned on the rotor and the inside of the case individually. A magnetic force is generated between the first and second magnets to limit the rotor to rotate in a predetermined position, increasing utility life of the pump.

  • Publication number: 20050200211
    Abstract: A spindle motor includes a stator structure and a rotor structure enclosing the stator structure. The stator structure has a stator base, a magnetic conductive structure surrounding the stator base, and a buffer structure provided in the gap defined by the stator base and the magnetic conductive structure and in contact with both the stator base and the magnetic conductive structure.
