PURPOSE: A spindle motor is provided to have strong resistance against the deformation by forming a plate type without an inflection point and combining the plate type with a rotor yoke. CONSTITUTION: The one side of a bearing housing(120) is supported by a base. The bearing(130) is fixed inside the bearing housing. A rotary shaft(140) supports the one side of the bearing and is rotatable. The stator(150) is arranged around the bearing housing. The rotor(160) is fixed on the other side part of the rotary shaft and is rotated by the interaction of the stator. A clamping device is arranged in the rotor. The secession of the disc loaded in rotor is prevented.
