马达的定子及其制造方法
摘要：
一种马达的定子及其制造方法，能缩短马达的定子的轴长，并且还能缩短径向。在马达的定子(10)中，线圈(17)的末端线(17a、17b)分别从线圈边端的供电侧、中性点侧拉出。将在圆周方向上相邻的第一相、第二相、第三相的三个线圈(17)设为一组，并将从中性点侧拉出的三根末端线(17b)中的一根的前端部与中间部分别连接剩余的末端线(17b)。采用将第一相的末端线和第二相的末端线彼此、以及第二相的末端线和第三相的末端线彼此分别在不同的位置连接的结构，以使一个接线部的大小紧凑化。
摘要（英）：

The present invention provides a motor stator and a manufacturing method thereof capable of shortening the axis length of the motor stator and shortening the radial direction. In the motor stator (10), terminal wires (17a, 17b) of a coil (17) are led out respectively from a feed-side and a neutral-side coil end. With three circumferentially adjacent first-, second-, and third-phase coils (17) as one set, the leading end portion and intermediate portion of one of three terminal wires (17b) led out from the neutral side are connected to each of the remaining terminal wires (17b). A structure wherein the first- and second-phase terminal wires are connected together in one position, and the second- and third-phase terminal wires are connected together in a different position from the one position, is adopted, thus compacting the size of one wire connection portion.
