US08416524B2 Spindle motor having connecting mechanism connecting lead wire and circuit board, and storage disk drive having the same 有权
主轴电动机具有连接引线和电路板的连接机构，以及具有该导线的存储盘驱动器

Spindle motor having connecting mechanism connecting lead wire and circuit board, and storage disk drive having the same
Abstract:
A spindle motor includes a base portion, a rotor hub, a stator, and a circuit board. The base portion preferably includes a through hole and is arranged to spread out radially around a central axis. The rotor hub is arranged above the base portion to rotate about the central axis. The stator is arranged above the base portion, and includes coils each including at least one lead wire. The circuit board is arranged radially outward of the through hole, and arranged on a lower surface of the base portion. The base portion includes a communicating groove arranged to join the through hole and the circuit board to each other. The at least one lead wire of the coils is arranged to pass inside the through hole and the communicating groove to be electrically connected to the circuit board. The through hole is sealed with a sealant.
Abstract(Chinese):

主轴电动机包括基部，转子毂，定子和电路板。 基部优选地包括通孔并布置成围绕中心轴径向扩展。 转子毂布置在基部上方以围绕中心轴线旋转。 定子布置在基部的上方，并且包括各自包括至少一根引线的线圈。 电路板布置在通孔的径向外侧，并且布置在基部的下表面上。 基部包括连通槽，该连通槽将通孔和电路板彼此连接。 线圈的至少一根引线布置成通过通孔和连通槽内的电连接到电路板。 通孔用密封剂密封。
