Patent ID: 7608969

Claim:
A rotary electric machine, comprising: a stator; an inner rotor disposed on a radial inside of the stator; and an outer rotor disposed on a radial outside of the stator, wherein the stator comprises: a plurality of stator cores arranged in a circumferentially spaced relation about a central axis of the stator, wherein each of the plurality of stator cores has a T-shape including a shank portion and a head portion, wherein the head portion is located on a radial outside of the stator core; and a molded resin filled in the space between adjacent stator cores, wherein the adjacent stator cores are spaced from each other and connected with each other through the molded resin filled in the space between the adjacent stator cores, wherein each of the plurality of stator cores includes a meshing portion which is meshed with the molded resin, wherein the meshing portion comprises a given recess, a given projection, and at least one of a second recess and a second projection alternately formed on each circumferentially opposed side surface of the head portion of the stator core such that the given recess, the given projection, and the one of a second recess and a second projection do not extend to the shank portion, and wherein each of the plurality of stator cores includes a plurality of stator segments laminated along a direction of the central axis so as to form the meshing portion.
