Abstract
A spindle motor includes a stator structure and a rotor structure coupled to the stator structure. The stator structure has a stator base, a magnetic conductive structure surrounding the stator base, and a first buffer structure provided in the gap defined by the stator base and the magnetic conductive structure and in contact with both the stator base and the magnetic conductive structure. Furthermore, a second buffer structure and a third buffer structure are respectively provided between the stator base and the casing and between the stator base and the base plate.
