機の巻線固定構造。 In a structure in which the winding is housed in an opening groove with a U-shaped cross section that penetrates the laminated iron core in the lamination direction, and the winding is fixed by driving a wedge into the groove opening at the top of the winding in the lamination direction,
One side of the opening groove is an inclined surface, and the width of the groove opening is larger than the width of the groove bottom, and a semiconductive cross-section is formed between the side surface of the winding housed in the opening groove and the inclined surface of the opening groove. A winding fixing structure for a rotating electric machine, characterized in that the winding is provided with a tapered wedge, and the wedge is further provided in a groove opening at the upper part of the winding.
