摘要： A spindle motor is disclosed, characterized by: a rotation shaft rotated by a stator and a rotor; a turn table rotated by the rotation shaft and accommodated by an optical disk; and a center cone moved along an axial direction of the rotation shaft for being brought into contact with an inner periphery of the optical disk to align a rotation center of the optical disk with a rotation center of the rotation shaft, wherein the center cone contacting the inner periphery of the optical disk is formed with a rise prevention unit configured to reduce a contact area with the inner periphery of the optical disk and to tightly contact the optical disk to the turn table.
摘要翻译：公开了一种主轴电动机，其特征在于：由定子和转子旋转的旋转轴; 由旋转轴旋转并由光盘容纳的转台; 并且中心锥体沿着旋转轴的轴向方向移动以与光盘的内周接触，以使光盘的旋转中心与旋转轴的旋转中心对准，其中中心锥体接触光盘的内周形成有上升防止部，其被配置为减小与光盘的内周的接触面积，并将光盘与转台紧密接触。
