Patent ID: 7772735

Claim:
An embedded magnet type rotating electric machine comprising a rotor, the rotor defining an axial direction and a circumferential direction, wherein the rotor includes: a rotor core defining a plurality of accommodating holes lined up in the circumferential direction, each of the accommodating holes passing through the rotor core in the axial direction, and each of the accommodating holes extending in the radial direction; and a plurality of magnets that are respectively arranged in the accommodating holes; wherein the rotor core includes: a plurality of core sheets laminated in the axial direction, the core sheets including a plurality of regulating core sheets each having a core-sheet radial regulating portion, and a plurality of non-regulating core sheets each having a space in a portion corresponding to the core-sheet radial regulating portion, the regulating core sheets alternating with the non-regulating core sheets in the axial direction; an extension portion in the circumferential direction extending further outward in the circumferential direction with respect to the magnet from at least one of a radially outer end and a radially inner end in the accommodating hole; and a radial regulating portion comprising the core sheet radial regulating portions of the plurality of the regulating core sheets, the radial regulating portion regulating a movement of the magnet in a radial direction, the radial regulating portion extending in the radial direction in such a manner as to correspond to a center in the circumferential direction of the accommodating hole, the radial regulating portion contacting only a circumferential center portion of a radial end of the magnet, and wherein a dimension in the circumferential direction of a portion of the radial regulating portion that is brought into contact with the magnet being smaller than a dimension in the circumferential direction of the magnet.
