STATOR WINDING OF DYNAMO-ELECTRIC MACHINE AND MANUFACTURING METHOD THEREFOR

PROBLEM TO BE SOLVED: To provide a dynamo-electric machine of a segmented conductor joint type which is superior in the properties of cooling and electrically insulating a stator winding, and its manufacturing method. SOLUTION: Many jointed end parts 5, structured by jointing a pair each of the end parts 4a of segmented conductors, are covered with an insulating resin film 6. The film 6 recesses and projects in the axial direction along the contour of the jointed end parts 5 in matching with the installation pitch of the end parts 5 in the circumferential direction. More specifically, the jointed parts 5 projects in the axial direction to be covered at the portions where the jointed parts 5 exist in the circumferential direction. The film 6 recesses in the axial direction at the portion where the jointed parts 5 do not exist in the circumferential direction, because the covering of the end parts 5 is not required.
