20120025647 | SPINDLE MOTOR - Disclosed herein is a spindle motor. The spindle motor includes a rotor and a stator. The rotor includes a rotating shaft and a rotor casing which is provided with a magnet. The stator rotatably supports the rotor. The stator includes an armature facing the magnet. When the rotor casing rotates at a low speed, the rotating shaft rotates in a state of being inclined at a predetermined angle with respect to the vertical direction in which the rotating shaft is upright on the stator. Therefore, because the rotating shaft rotates in the state of being inclined with respect to the stator, the rotor can uniformly rotate. If the spindle motor is used in an optical disk apparatus for forming a label surface on an optical disk, the quality of the image on the label surface of the optical disk can be enhanced. | 02-02-2012 |

20130093283 | SPINDLE MOTOR - Disclosed herein is a spindle motor. The spindle motor uses a general (non neodymium) permanent magnet rather than a neodymium magnet as a permanent magnet and compensates for a reduced counter electromotive force (B-EMF) value by allowing the center of a connection part formed in a round shape between poles around which coils are wound to be different from that of a core to increase a coil inductance value, thereby making it possible to easily sense and control a rotation state of the spindle motor. | 04-18-2013 |
