LAMINATED CORE OF ROTARY ELECTRIC MACHINE, METHOD FOR MANUFACTURING LAMINATED CORE OF ROTARY ELECTRIC MACHINE, AND ROTARY ELECTRIC MACHINE

摘要

A laminated core of a rotary electric machine having: a first spiral core constituent body layer configured by linking a plurality of metal first core constituent pieces that have a magnet mounting part, the first spiral core constituent body layer being wound in a spiral shape as an integral body; and a second spiral core constituent body layer configured by linking the plurality of first core constituent pieces and a metal second core constituent piece that has a magnet mounting part, the second core constituent piece having a different longitudinal-direction length than do the first core constituent pieces, and the second spiral core constituent body layer being wound in a spiral shape as an integral body. The second spiral core constituent body layer is laminated on the first spiral core constituent body layer in continuation with the first spiral core constituent body layer.
