  • Patent number: 9891407
    Abstract: A lens driving module for driving a lens along an optical axis is provided. The lens driving module includes a stator having a hollow cylindrical shape through which the optical axis passes through and including coils, a rotator having a hollow shape through which the optical axis passes, mounted on an outer side of the stator, capable of rotating with respect to the stator with the optical axis as a center line, and including magnets facing the coils, and at least one of rotation connecting members connecting the rotator to the stator such that the rotator may rotate with respect to the stator to maintain a gap between the coils and the magnets.

  • Patent number: 9465229
    Abstract: An image stabilizer includes a correction lens module including a correction lens and a correction lens supporting plate to which the correction lens is coupled, a plurality of drivers configured to move the correction lens module in a direction perpendicular an optical axis, each driver including a magnet member fixed to the correction lens supporting plate and a coil configured to react to the magnet member, and a plurality of location restoration units disposed to face the plurality of drivers, configured to restore the correction module to an initial location, and including magnetic bodies. The magnet member may include a first magnet, a second magnet, and a third magnet coupled in one body.

  • Publication number: 20150364961
    Abstract: A brushless motor in which a stator and a rotor are arranged relative to one another in a direction of a rotational axis is provided. The rotor may include a plurality of annularly arranged permanent magnets which are N-poles and S-poles that alternate with each other about the rotational axis of the rotor. The stator may include first teeth annularly arranged and facing the plurality of permanent magnets in the direction of the rotational axis, and a plurality of coils corresponding to the first teeth.
