Abstract
A motor has a stator core having a plurality of salient poles and stator coils wound on the salient poles, respectively, each of the stator coils having a common side coil end part and a coil winding part. The common side coil end part of each of the stator coils extends radially outward from corresponding one of the coil winding parts into a region radially outside of the corresponding coil winding part of the corresponding stator coil. Then, the common side coil end part is bent to extend in the circumferential direction towards adjacent one of the salient poles in the circumferential direction, and connects electrically to a common side coil end part of adjacent one of the stator coils, wherein the common side coil end parts are joined to surround in a circular ring-shaped manner an entire outer circumference of the stator core.
