摘要： PROBLEM TO BE SOLVED: To provide a dynamo-electric machine which is equipped with dynamo-electric machine winding capable of preventing the damage of an insulator or the damage of a rectangular conductor.
SOLUTION: The core (8) of a dynamo-electric machine, which has a plurality of dynamo-electric machine winding elements (1) that are equipped each with a twisted part 3 being made by twisting the rectangular conductor 2 by 180° in its longitudinal direction and U-shaped winding element ends 4 being made by bending both sides of this twisted part 3 in the same direction and a plurality of winding grooves 9 that accommodate and fix above and below both the U-shaped feet 5A and 5B of this dynamo-electric machine winding element (1), and the adjacent U-shaped feet 5A and 5B of the above dynamo-electric machine winding element (1) projected from the above winding grooves 9 are joined with each other. The rectangular conductor 2 ceases to be forced into large transformation by twisting the winding element ends 4 by 180° in its longitudinal direction, consequently it can prevent the damage of a covered insulator or the break of the rectangular conductor itself or the occurrence of cracks.
