In the figure, 1 is a fixed core, 101 is a groove, 102 is a ventilation duct, 2 is a wire ring piece, 201 is a wire ring piece conductor, 202 is an insulating layer, 3A and 4A are first and second spacers, 301, 4
01 is a notch. Note that the same parts in each figure are given the same reference numerals.

Claims (1)

[Scope of utility model registration request] An iron core having a groove provided in the axial direction and into which a wire ring piece is inserted, and a ventilation duct provided orthogonally to the groove and introducing cooling air to cool the wire ring piece, and a side wall of the wire ring piece and the groove. Alternatively, a spacer is installed between the bottom surface and at least one of the bottom surfaces and has a notch or a through hole in a portion corresponding to the ventilation duct, and the cooling air introduced from the ventilation duct is passed through the notch or the through hole. A rotating electrical machine that improves the cooling effect by directly contacting the coil segments.
