LAMINATED CORE OF DYNAMO-ELECTRIC MACHINE, METHOD FOR MANUFACTURING LAMINATED CORE OF DYNAMO-ELECTRIC MACHINE, AND DYNAMO-ELECTRIC MACHINE

WIPO Patent Application WO/2018/163852

A1

A laminated core of a dynamo-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. At least one second core constituent piece is provided to the front of the second spiral core constituent body layer. The magnet mounting part of the second spiral core constituent body layer is displaced from the magnet mounting part of the first spiral core constituent body layer in the circumferential direction of the laminated core.
