Abstract
PURPOSE:To shorten the length of the entire revolving shaft of a motor by integrating a rotor yoke and the clamp case of a disk clamp into one part, and mounting the part in one position on the revolving shaft. CONSTITUTION:The rotor yoke 4 is engaged with the revolving shaft 3 on its disk-loading side, and a magnet 6 for magnetic field is disposed so that the magnet 6 faces to a stator 7 with a radial gap between them. The cylindrical clamp case part 4d is formed integrally with the rotor yoke 4 protruding toward the disk-loading side opposite to the rotor yoke 4 side, and further, a disk attracting magnet 12 is mounted on the inside surface of the clamp case 4d. In such a way, the disk clamp is constituted integrally on the rotor yoke 4. As a result, the length of the entire revolving shaft of the motor can be shortened.
