Abstract:
A lens driving device includes a housing; a lens barrel disposed in the housing so as to support comprising a lens; and a location adjustment unit providing configured to apply a force for rotation of to the lens barrel and guiding to guide a rotation of the lens barrel.
Abstract:
Embodiments of the invention provide a motor rotor including a shaft, a rotor core having the shaft coupled thereto, and a balancing part formed integrally with the rotor core and the shaft, wherein the balancing part includes a balancing protrusion protruding therefrom.
Abstract:
Embodiments of the invention provide a motor assembly including a terminal provided at a stator of a motor and electrically connected to a coil wound around the stator, and a controller formed with a coupling hole to which the terminal is coupled and electrically connected and controlling electric input and output to the terminal.
Abstract:
There are provided a fluid dynamic pressure bearing assembly, a spindle motor including the same, an electronic blower including the same, and a vacuum cleaner including the same. The fluid dynamic pressure assembly includes: a shaft fixedly installed on a base member; and a sleeve having an axial hole fixed to an outer circumferential surface of the shaft and rotatably supported by fluid dynamic pressure, wherein when the sleeve is inclined, based on an axial direction while being rotated, the sleeve comes into line-contact or surface-contact with the shaft in the axial direction.
Abstract:
A camera module includes a coil member, a magnet member, and a sensor member. The coil member is positioned on a first surface of a fixed unit. The magnet member is positioned on a movable unit and facing the coil member. The sensor member is positioned on a second surface of the fixed unit and configured to sense a position of the movable unit.
Abstract:
A camera module includes a fixed unit having an accommodating space; a moveable unit disposed in the accommodating space; an actuator configured to drive the movable unit in an optical axis direction; a substrate, disposed on a first side surface of the fixed unit, including a coil member of the actuator disposed on a first surface of the substrate; and connection pads, disposed on a second surface of the substrate, electrically connected to the coil member.
Abstract:
A lens driving device includes a lens barrel; a lens disposed in the lens barrel; a plurality of magnets disposed on an external surface of the lens barrel; a guide member coupled to the lens barrel configured to move the lens barrel in an optical axis direction; a first coil disposed on one side of the guide member opposite to one of the plurality of magnets; a base supporting the guide member configured to move the guide member in a direction orthogonal to the optical axis direction; and a second coil disposed on a side wall of the base opposite to a magnet which is not opposite to the first coil.
Abstract:
Disclosed herein is an electric blower including: an impeller; a driving module including a rotor part coupled to the impeller in order to driving the impeller and a stator part, the rotator part including a magnet and the stator part including an armature formed of a core positioned so as to face the magnet and a coil; a motor housing having the driving module mounted thereon; and a control module mounted on the motor housing and controlling the driving module.
