Abstract
The present invention relates to a spindle motor employed for a disk player. The spindle motor comprises: a deck plate; a shaft rotatably disposed on the deck plate; a stator having a core wound with coils which is disposed on the outer peripheral surface of the shaft and generates a magnetic force; a magnet which is provided at the upper part of the stator and generates a magnetic force; a cap type rotor which is coupled to the upper end of the shaft integrally with the shaft so as to be located at the upper part of the pulling magnet and the stator and is provided on the upper part with a track having a different height from another; a magnet which is disposed on the inner peripheral surface of the rotor so that it can be opposed to the core of the stator with an air gap therebetween; and a turntable which is disposed on the upper surface of the rotor integrally with the rotor and mounts a disk.
