| titleOfInvention | Spindle motor |
| abstract | (57) Abstract: Provided is a spindle motor which has high rotation accuracy and hardly decreases in rotation accuracy due to temperature change, and is suitable for driving a hard disk drive of a hard disk drive. A plurality of rolling bearings provided with rolling elements between an inner ring and an outer ring around a shaft fixed to a base. In a spindle motor in which a rotor hub 8 which is a rotating member of a motor is rotatably supported via a cylindrical member, an upper and lower opening is provided between an outer peripheral surface of the rolling bearing and an inner peripheral surface of a central vertical hole 9 of the rotor hub 8. The material of the sleeve 5 and the material of the outer rings 3b and 4b of the rolling bearing are made of an iron-based metal having substantially the same expansion coefficient, and the material of the inner rings 3a and 4a of the rolling bearing is The material of the shaft 2 was also made of an iron-based metal having substantially the same expansion coefficient. |
