Abstract
Each of a plurality of unit windingsis formed by being divided into a first winding sectionhaving opened end portions and a second winding section, and the first winding sectionis shaped in such a manner that a step in radial direction of a stator coreis formed between opposing side sectionsandand the opened end sections are bent in the crossing over direction of the winding so that open endsandof the opened end sectionsoppose each other in the radial direction of the stator core, then the open endsandare connected by winding conductor piecesandof the second winding section to complete the unit winding, thereby, end sections of a stator winding are shortened and a small size dynamo electric machine is realized.
