Abstract: A spindle motor includes a stator including a base member having a stator core installed thereon; and a rotor including a rotor hub in which a driving magnet facing the stator core is installed. The rotor hub includes a disk-shaped body, a magnet mounting part extended from edge of the body in a downward axial direction and having the driving magnet installed on an inner surface thereof, and a disk support part extended from the magnet mounting part in radial direction. A magnetic center of the driving magnet is higher than that of the stator core in the axial direction in order to generate force directed in the downward axial direction through interaction with the stator core. The magnet mounting part includes a vortex generation suppressing part disposed on a lower edge portion thereof to decrease noise and vibrations generated by flow of air during rotation of the rotor hub.

Abstract: An actuator includes a magnet, a driving coil facing the magnet, a driver, and a position calculation processor. The driver is configured to move the magnet in at least one of an optical axis direction and a direction perpendicular to the optical axis by applying a driving signal to the driving coil. The position calculation processor includes sensing coils, and is configured to calculate a position of the magnet according to inductance levels of an inductor of the sensing coils. The inductance levels vary according to movements of the magnet.
