交流发电机刷架
摘要：
一种具有旋转轴线的用于交流发电机的刷架组件，包括一对电刷，每个电刷具有限定有宽度和高度的接触表面，并且每个电刷具有从电刷沿高度方向横向延伸的分流线。刷架组件包括壳体，壳体具有：第一电刷腔室和第二电刷腔室；对应的第一分流线腔体和第二分流线腔体，每个腔体限定腔体高度；以及第一和第二狭槽，第一和第二狭槽分别插置在所述对应的腔室与腔体之间。相应的分流线延伸穿过所述第一凹槽和第二凹槽并且随后穿过第一分流线腔体和第二分流线腔体。腔体高度各自为所述电刷中的一个的高度的至少大约0.9倍。所述第一分流线腔体的高度小于大约0.97×((A/2)+B)，其中，A为电刷高度，而B为介于电刷之间的距离。
摘要（英）：

A brush holder assembly for an alternator having a rotational axis includes a pair of brushes each having a contacting surface defining a width and a height, and each having a shunt wire extending laterally from the brush in the widthwise direction. The brush holder assembly includes a housing having first and second brush chambers, corresponding first and second wire cavities each defining a cavity height, and first and second slots respectively interposed between the corresponding chamber and cavity. The respective shunt wires extend through the first and second slots then through the first and second wire cavities. The cavity heights are each at least approximately 0.9 times the height of one of the brushes. The height of the first wire cavity is less than approximately 0.97 times ((A/2) plus B), wherein A is the brush height and B is the distance between the brushes.
