摘要
It has a stator in which a second iron core, which is a laminate of amorphous soft magnetic metal or nanocrystalline soft magnetic metal, is arranged on a first iron core, which is a laminate of electrical steel sheets, and has excellent characteristics and reliability. Provided are a stator for a rotary electric machine and a rotary electric machine, a method for manufacturing a stator for a rotary electric machine, and a method for manufacturing a rotary electric machine. A stator for a rotary electric machine, the stator is an annular first iron core portion which is a laminate of electrical steel sheets and a second iron core which is a laminate of amorphous soft magnetic metal or nanocrystalline soft magnetic metal. The first annular core portion having a portion is formed by a plurality of teeth portions in which a coil is wound so as to project toward the inner peripheral side and a first portion formed in each of the teeth portions from an outer peripheral surface. The second iron core portion is a stator for a rotary electric machine, characterized in that the groove portion is provided in the first groove portion.
