Rotating Electrical Machine

摘要

A rotating electrical machine includes a stator with an iron core having a plurality of slots and a stator winding configured by connecting a plurality of segment conductors each formed by a rectangular wire including an end portion and an insulating film; and a rotator that faces the stator through a gap, wherein the conductor includes a portion coated with the insulating film and a peel-off portion from which the insulating film is peeled off and has a cross-section smaller than the coated portion, the segment conductor and another segment conductor are bonded to each other outside the slots so as to bring at least parts of the peel-off portions as bonding faces into contact with each other, at least one segment conductor of the bonded segment conductors includes a straight portion that is formed in a linear shape in an axial direction and an arc portion.
