    • A low profile spindle motor for supporting and rotating media disk or disks of a hard disk drive includes a plurality of stator teeth, a winding layer which may be formed by printed circuit board or the like, and a rotor. The plurality of stator teeth are disposed in an annular region surrounding an axis of rotation of the motor, and have projected ends for increasing the tooth area facing a magnet ring of the rotor. The winding layer has a plurality of windings disposed surrounding the axis of rotation. Each winding is coupled to one of the plurality of stator teeth. The magnet ring is positioned radially spaced apart and coplanar with the annular region. The magnet ring has magnetic poles annularly distributed to generate magnetic fluxes along radial direction. Spindle motor formed according to the invention has a low profile, improved performance and manufacturability.
    • 用于支撑和旋转硬盘驱动器的介质盘或盘的小型主轴电机包括多个定子齿,可由印刷电路板等形成的绕组层和转子。 多个定子齿设置在围绕电动机的旋转轴线的环形区域中,并且具有用于增加面向转子的磁环的齿面积的突出端。 绕组层具有围绕旋转轴设置的多个绕组。 每个绕组联接到多个定子齿中的一个。 磁环位于径向间隔开并且与环形区域共面。 磁环具有环形分布的磁极,以沿径向产生磁通量。 根据本发明形成的主轴电机具有低轮廓,改进的性能和可制造性。
