PROBLEM TO BE SOLVED: To prevent exfoliation or the like of a coating film at an inflection portion of a turn portion projected from an end surface of a core of a plurality of conductor segments constituting a conductor coil, in a stator of a dynamoelectric machine. SOLUTION: In the stator constituted of the core 32 and the conductor coil 68, the conductor coil is constituted of external conductor segments 40 and internal conductor segments 50 both of which have a pine needle shape. One linear portion 41 of the k-th external conductor segment forms the innermost layer of the k-th slot 34a, and the other linear portion 42 forms the outermost layer of a first slot 34b. The k-th outside turn portion 43 which is projected from the end surface 36 of the core and bonds the innermost layer and the outermost layer is warped in an S-shape when viewed form an end surface. The inflection point 44c of an outside flexure portion is positioned at the innermost layer side rather than an intermediate point 44d of the k-th outside turn portion. COPYRIGHT: (C)2004,JPO&NCIPI
