PURPOSE: A spindle motor is provided to reduce the number of parts and assembling processes by employing a rotor having an integrated structure. CONSTITUTION: A bearing assembly(10) comprises a bearing(1) and a bearing housing(9) accommodating the bearing. A stator(20) is fixed to the exterior of the bearing housing. A rotary shaft(30) is inserted and rotated in the bearing. A rotor(40) comprises a clamp(41) for clamping an optical disk, a bushing part(42) protruded from the underside of the clamp along the central through hole of the clamp, a support part(43) protruded from the outer periphery of the bushing part, a yoke(48) coupled to the support part, and a magnet(49) coupled to the inner side of the yoke. |
