A spindle motor is provided to prevent damage to a part by easily separating a rotor and a rotation axis from a bearing housing in order to replace or repair the part. One surface of a bearing housing(120) is fixed to a base(110). The other surface of the bearing housing is opened. A bearing is fixed inside the bearing housing. A rotation axis(140) is rotatably supported to the bearing. A stator(150) is arranged around the bearing housing. A rotor(160) includes a rotor yoke(161) and a magnet(165). The rotor yoke is coupled in the rotation axis. The magnet is coupled in the rotor yoke. One side of a stopper(190) is detachably coupled in the base. The other side of the stopper is fixed to the rotor. The stopper prevents separation of the rotor and rotation axis from the bearing housing.
