US Patent 11894726 Rotating electric machine

In a rotating electric machine, a rotor core includes; a gap surface; a plurality of magnet insertion holes; a slit which is formed in a core region between the gap surface and, among the plurality of magnet insertion holes, a magnet insertion hole into which a permanent magnet forming one magnetic pole is inserted, and divides the core region into a plurality of divided core regions in the circumferential direction; and a cutout formed by denting the gap surface of a divided core region, wherein a shortest distance between a stator core imaginary gap surface which is in contact with distal end surfaces of the plurality of teeth, and a bottom point of the cutout is longer than a shortest distance between the stator core imaginary gap surface and each of two intersections between the cutout and the gap surface.
