定子单元以及马达
摘要：
提供定子单元以及马达，能够在汇流条单元中削减导电材料的使用量，减少部件数量。定子单元具有定子和配置在定子的上侧的汇流条单元，定子具有铁芯背部、多个齿和多个线圈，所述多个线圈为三个线圈组，各线圈组是由包括搭接线的一根导线形成的两个以上的线圈，所述汇流条单元具有：与三个线圈组的导线的一个端部连接并包括外部连接端子的三个第一汇流条；与所述导线的另一个端部连接的用于中性点的第二汇流条；保持所述三个第一汇流条和所述第二汇流条的树脂保持架，所述三个第一汇流条的所述外部连接端子集中配置在以中心轴线为中心的周向上的一个区域，所述三个第一汇流条与所述第二汇流条只在以中心轴线为中心的径向和轴向中的某一方上重叠。
摘要（英）：

A stator portion includes a stator and a bus bar member. The stator includes three coil groups, each coil group includes two or more coils defined by a single conducting wire including a jumper wire. The bus bar member includes three first bus bars to which end portions on one side of the conducting wires of the three coil groups are connected, each of which includes an external connection terminal, a second bus bar defining a neutral point to which end portions on the other side of the conducting wires are connected, and a resin holder which retains the three first bus bars and the second bus bar. The three first bus bars and the second bus bar overlap only in a radial direction centered on the central axis or an axial direction, and the maximum number of bus bars which overlap is 2.
