PURPOSE: A spindle motor is provided to reduce vibration and noise by improving the verticality of a rotary shaft based on a base. CONSTITUTION: A coupling tube is formed n the center of a base(110). A hanging frame is formed on one side of a bearing housing(120). The other side of the bearing housing is inserted into the coupling tube. A bearing(130) is fixed to the bearing housing. A rotary shaft(140) is rotatably supported by the bearing. A stator(160) includes a core and a coil. The core is fixed to the outer circumference of the bearing housing. The coil is wound around the core. The rotor includes a rotor yoke and a magnet.
