Abstract: There is provided a spindle motor including: a stator rotatably supporting a rotor; and a stator core fixed to the stator and having a front end disposed to face a driving magnet included in the rotor and a coil wound therearound, wherein the stator includes a base member, an insertion groove being formed in the base member, and having a lower portion of the coil inserted therein.

Abstract: There is provided a spindle motor including: a base member; a shaft fixed to the base member and including a lower thrust member disposed on a lower end portion thereof and an upper flange member disposed on an upper end portion thereof; and a rotating part forming, together with the upper flange member, the lower thrust member, and the shaft, bearing clearances filled with a lubricating fluid, and rotated around the shaft, wherein the lower thrust member includes amounting part on which a stator core is mounted, and at least one of a surface of the lower thrust member disposed to face a surface of the rotating part and the surface of the rotating part includes a lower thrust dynamic pressure generating groove formed therein.

Abstract: A spindle motor includes a base member formed of a magnetic material; a lower thrust member installed in the base member; a shaft fixedly installed on at least one of the lower thrust member and the base member; a sleeve rotatably supporting the shaft by fluid dynamic pressure and disposed above the lower thrust member to form a thrust dynamic pressure bearing together with the lower thrust member at the time of rotation thereof; a rotor hub coupled to the sleeve to rotate together therewith; and an upper thrust member fixedly installed on the shaft to be positioned above the sleeve and forming a thrust dynamic pressure bearing together with the sleeve at the time of rotation of the sleeve, wherein upward thrust dynamic pressure generated between the lower thrust member and the sleeve is greater than downward thrust dynamic pressure generated between the upper thrust member and the sleeve.

Abstract: A method of manufacturing a film antenna includes: preparing a carrier film formed of an insulation polymer material; forming an antenna radiator on at least one side of the carrier film by one of sputtering and deposition; inserting the carrier film with the antenna radiator formed thereon into a mold having a shape of a mobile communication terminal case; and forming a mobile communication terminal case integrally formed with the carrier film by injecting a molding material into the mold.
