PURPOSE: A motor is provided to stabilize the rotation of a disk and a motor by forming a constant flow of air on a surface of a disk. CONSTITUTION: A rotor(110) is combined with a disk. The rotor includes an air inflow hole which is formed at one surface thereof facing the disk so as to receive the air. The rotor includes an air discharging hole which is formed at an outer circumference thereof so as to discharge the air. A stator(150) is used for supporting rotatably the rotor. A rotor case(120) is used for forming an air inflow hole at one surface facing the disk. |
