Abstract
A stator coil of a rotary electric machine such as an alternator for use in an automobile is composed of a plurality of U-shaped conductor segments inserted into slots formed in a stator core. Each segment has a head portion and two legs extending from the head portion. The plurality of segments include regular segments each having a regular distance between two legs (a regular slot-pitch) and special segments each having a special slot-pitch different from the regular slot-pitch. The head portions of both the regular and the special segments are simultaneously twisted to form the respectively required slot-pitches after a preliminary twist is given to the special segments. In this manner, a process of manufacturing the stator coil is simplified.
