    • A motor is disclosed. In accordance with an embodiment of the present invention, the motor includes a rotational axis, a rotating body, which rotates together with the rotational axis as one unit, a hub having a ring-shaped body and a protruding part, in which the ring-shaped body is interposed between the rotational axis and the rotating body and the protruding part is protruded from the ring-shaped body towards the rotational axis and is in contact with the rotating body so as to extend an outer circumferential surface of the ring-shaped body coupled to the rotating body, and a housing, which supports and rotates the rotational axis, in which the housing having a supporting part is interposed between the rotational axis and the protruding part of the hub and supports the rotational axis. Thus, the rotor can be safely supported, providing the rotational stability of the rotor.

    • A disk drive for driving a disk is disclosed, which includes: a driving unit configured to provide a driving force onto the disk, a main circuit pattern electrically connected with the driving unit, a sensor unit configured to sense a rotation speed of the disk, a first board supporting the sensor unit, a second board supporting the first board, and a base plate supporting the second board and the driving unit. One of the first board and the second board can be a flexible board electrically connecting the sensor unit with the main circuit pattern, and the other of the first board and the second board can be a rigid board. This disk drive can be utilized to ensure the distance between the sensor unit and the disk required for a rotation sensor to measure the rotation speed of the disk.
    • 公开了一种用于驱动盘的磁盘驱动器,其包括:驱动单元,被配置为向盘提供驱动力,与驱动单元电连接的主电路图案,被配置为感测盘旋转速度的传感器单元, 支撑传感器单元的第一板,支撑第一板的第二板和支撑第二板和驱动单元的底板。 第一板和第二板之一可以是将传感器单元与主电路图案电连接的柔性板,并且第一板和第二板中的另一个可以是刚性板。 该磁盘驱动器可用于确保传感器单元与旋转传感器所需的盘之间的距离以测量盘的转速。
