Abstract
Official abstract text for this publication.
A stacked core includes a plurality of core pieces that are arranged in a stack. Each of the core pieces has a plurality of magnet insertion holes. A bridge is provided between a radially-outer end of each of the magnet insertion holes and an outer region of each of the core pieces, A radially-outer contour of the bridge is provided on a radially-inner side of a blanking-contour line of each of the core pieces.
First claim
Opening claim text (preview).
What is claimed is: 1. A stacked core comprising: a plurality of core pieces in a stack, each of the core pieces having a plurality of magnet insertion holes; and a bridge provided between a radially-outer end of each of the magnet insertion holes and an outer region of each of the core pieces, wherein a radially-outer contour of the bridge is provided on a radially-inner side of a blanking-contour line of each of the core pieces, wherein a thickness of the bridge in a stack direction of the core pieces is smaller relative to an area adjacent to the bridge. 2. The stacked core according to claim 1 , further comprising: a non-core region provided between a long side on a radially-outer side of each of the magnet insertion holes and the outer region of each of the core pieces. 3. The stacked core according to claim 1 , further comprising: a through hole having a radially inner side which defines the radially-outer contour of the bridge.
