摘要： In one example, a FDB motor having a top-cover attached, EM biased bearing system is provided. The motor includes a shaft and rotor disposed for relative rotation, and an axial limiter for restricting axial movement of the rotor with respect to the shaft, wherein the axial limiter is wet or lubricated during contact. The limiter is spatially fixed with respect to one of the shaft or the rotor and disposed with an axial end surface opposing a surface portion spatially fixed with respect to the other of the shaft or the rotor to form a gap therebetween. The gap may be filled with a fluid such as bearing lubricant, thereby providing a lubricated or wet contact surface to restrict axial movement of the shaft and rotor. Additionally, one or both surfaces may include a groove or slot to provide circulation of fluid through the gap.

摘要： A robust spindle motor is provided having added shock resistance for fluid containment. In an aspect, a high-speed centrifugal capillary seal contains a fluid reservoir extending between similarly rotatable components. Fluid is recirculated through the motor and substantially around a counterplate. Proper axial positioning of motor components and stiffness is maintained in motors supporting heavy loads such as a disk drive memory system having a weighty disc pack. In an aspect, two separate thrust surfaces provide oppositely directed axial forces acting on motor components. In an aspect, a single thrust plate that is comparatively small is utilized, reducing power consumption. Also, a thrust bearing situated inboard of a capillary seal forms a comparatively small diameter thrust plate gap. The comparatively small diameter thrust plate gap increases efficiency and characteristics including surface flatness, run out and perpendicularity are improved.
摘要翻译：提供了一种坚固的主轴电机，具有增加的防止流体容纳的冲击。在一方面，高速离心毛细管密封件包含在类似可旋转部件之间延伸的流体储存器。流体通过马达再循环并且基本上围绕着对面板。电动机部件的正确轴向定位和刚度保持在支撑重负载的电动机中，例如具有重量盘组件的磁盘驱动器存储器系统。在一个方面，两个单独的推力表面提供作用在马达部件上的相反方向的轴向力。在一方面，使用相对较小的单个推力板，从而降低功率消耗。此外，位于毛细管密封件内侧的推力轴承形成相对较小直径的推力板间隙。相对较小直径的推力板间隙增加了效率和特性，包括表面平整度，磨损和垂直度均得到改善。
