STATOR FOR ROTATING ELECTRICAL MACHINE, ROTATING ELECTRICAL MACHINE, METHOD FOR MANUFACTURING STATOR FOR ROTATING ELECTRICAL MACHINE, AND METHOD FOR MANUFACTURING ROTATING ELECTRICAL MACHINE

摘要

Provided are: a rotating electrical machine having excellent characteristics and reliability, and including a stator in which second iron core portions, which are stacked bodies comprising an amorphous soft magnetic metal or a nanocrystalline soft magnetic metal, are disposed in a first iron core portion, which is a stacked body comprising electrical steel plates; the stator for the rotating electrical machine; a method for manufacturing the stator for the rotating electrical machine; and a method for manufacturing the rotating electrical machine.　This stator for a rotating electrical machine is characterized by including an annular first iron core portion, which is a stacked body comprising electrical steel plates, and second iron core portions, which are stacked bodies comprising an amorphous soft magnetic metal or a nanocrystalline soft magnetic metal, wherein: the annular first iron core portion includes a plurality of tooth portions which project toward the inner circumferential side and around which a coil is wound, and first groove portions formed within each tooth portion from an outer circumferential surface; and the second iron core portions are arranged in the first groove portions.
