PURPOSE: A spindle motor is provided to reduce the number of components by removing an additional support unit to control a space between a disk and an encoder within a preset range. CONSTITUTION: A base(100) forms a folding unit. A stator(500) is installed on the base. A rotor(600) rotates by mutually and electromagnetically operating with the stator. An encoder senses the rotation speed of the disk rotated by the rotor. A substrate(700) transmits information sensed from the encoder to the outside. |
