    • An objective is to provide a motor stator that may achieve: a reduction in parts costs by shaping coil ends so that length thereof is reduced, thereby reducing the amount of use of copper, and minimizing the amount of use of binding strings for securing the coil ends in place; a reduction in manufacturing process costs by a structure which allows a protector and a wire lead outlet part to be easily assembled; and then an improvement in quality of a stator by firmly holding the coil ends and the protector. The motor stator may include a stator core 1 including slots; a plurality of cut surfaces forming flat surfaces on the outer surface of the stator core 1; end surface insulating plates 2 formed in an approximately same shape as the shape of magnetic steel plates punched out, and assembled into the stator core 1 on both axial end surfaces thereof; projections formed in a vicinity of a peripheral portion of an end surface insulating plate 2, and engaged with the cut surfaces on the stator core 1; slot-like cutouts, a little larger in size than the slots, formed on an inner peripheral side of the each end surface insulating plate 1; and coil ends. The coil ends are shaped by pressure against the end surface insulating plates 2.
    • 目的是提供一种电动机定子,其可以实现:通过使线圈端部成形使其长度减小从而减少铜的使用量,并且最小化用于固定线圈的结合线的使用量来减少零件成本 结束到位 通过能够容易地组装保护器和电线引出口部的结构来减少制造工艺成本; 然后通过牢固地保持线圈端部和保护器来改善定子的质量。 电动机定子可包括包括槽的定子芯1; 在定子铁芯1的外表面上形成平坦表面的多个切割面; 端面绝缘板2形成为与冲压出的电磁钢板的形状大致相同的形状,并且在其两个轴向端面上组装到定子铁芯1中; 形成在端面绝缘板2的周边部附近并与定子铁芯1上的切断面接合的突起; 形成在每个端面绝缘板1的内周侧上的尺寸比槽大一点的槽状切口; 和线圈端。 线圈端部通过压靠端面绝缘板2成形。

    • Embodiments of the present invention prevent a magnetic disk drive from increasing in size and in manufacturing cost and reduces a positioning error of a magnetic head. An embodiment of a magnetic disk drive in accordance with the present invention includes: a disk-shaped magnetic disk that is rotated and driven; a magnetic head that reads and writes information to and from the magnetic disk, an arm that supports and moves the magnetic head; a spoiler that is close to a disk surface and extends in a radial direction of the disk; and a cabinet that houses these parts. The spoiler is disposed closer to an upstream side in a rotational direction of the disk than the arm and has a flow rate suppressing clearance positioned in a central portion in a peripheral direction of the spoiler, opened to both sides in an axial direction, and formed in a shape elongated in a radial direction of the disk.
    • 本发明的实施例防止了磁盘驱动器的尺寸和制造成本的增加并降低了磁头的定位误差。 根据本发明的磁盘驱动器的实施例包括:旋转和驱动的盘形磁盘; 从磁盘读取和写入信息的磁头,支撑并移动磁头的臂; 扰流器,其靠近盘表面并沿盘的径向方向延伸; 和一个装有这些部件的橱柜。 该扰流板配置在比臂更靠近盘的旋转方向的上游侧,并且具有位于扰流器的周向的中心部分中的沿轴向两侧开口的流量抑制间隙,并形成 在圆盘的径向方向上延伸的形状。
