摘要： Fluid bearing mechanisms (6a and 6b) are formed between a shaft (2) and a central part (21) of an oil impregnated sintered sleeve (13). The oil impregnated sintered sleeve (13) has such an inner surface formed to be larger in aperture ratio at a thrust support end (23) and a loading end (22) than at a central part (21). With this configuration, it is possible to achieve a brushless motor which can suppress an increase in bearing loss while obtaining necessary bearing stiffness at high rpm.
摘要翻译：流体轴承机构（6a和6b）形成在浸油烧结套筒（13）的轴（2）和中心部分（21）之间。油浸烧烧结套筒（13）具有这样的内表面，该内表面形成为在推力支撑端（23）和加载端（22）处的开口率大于在中心部分（21）处的开口率。利用这种构造，可以获得能够在高转速下获得必要的轴承刚度的同时抑制轴承损耗增加的无刷电动机。
