Stator for rotating electrical machine, rotating electrical machine, and method for manufacturing stator for rotating electrical machine

Abstract

When split iron cores are assembled with each other, a plurality of positioning steps are required, which results in an increase in man-hours, complication of equipment, and an increase in processing cost. When a first split iron core and a second split iron core which are adjacent to each other are joined, a first convex part of the first split iron core and a second concave part of the second split iron core are respectively close to and contacted with each other from the circumferential direction in a state that the first split iron core and the second split iron core are staggered in the height direction; one or both of the second concave portion and the first convex portion is / are slid in the height direction, the first groove portion of the first split iron core is engaged with the second tenon portion of the second split iron core, and the first tenon portion of the first split iron core is engaged with the second groove portion of the second split iron core.
