Abstract: A rotor for a rotating electric machine includes a core body having a through-hole, a magnet, a tubular portion, and a plate part having an opening. The through-hole passes through the core body in a thickness direction. The magnet is disposed on an outer wall of the core body. The tubular portion is placed radially-outward of the core body. The plate part seals at least one end of the tubular portion in an axial direction. The opening is provided at a position corresponding to the through-hole and passes through the plate part in a thickness direction. The through-hole is one of a plurality of the through-holes, and the magnet is one of a plurality of the magnets.

Abstract: A rotor has a projection part projected from an inner wall of a central hole part toward a central axis and a rib part defined between opening parts adjacent with each other in a circumferential direction. A first imaginary straight line is defined to extend from the central axis outward in a radial direction through a center of the projection part. The projection part is formed so that the first imaginary straight line passes the opening part. A second imaginary straight line is defined to extend from the central axis outward in the radial direction through a center of the rib part. The rib part is formed so that the second imaginary straight line passes a center of a pole part or an intermediate position between pole parts adjacent with each other in the circumferential direction.

Abstract: A stator core is a stack body of plural plates. Each plate includes an annular back yoke part, plural top-connected tooth parts, plural top-separated tooth parts, plural magnetic path parts and plural top open parts. The top-connected tooth part and the top-separated tooth part protrude from the back yoke part in a radial direction. The top magnetic path part connects top ends of two top-connected tooth parts. The top open part is open to a rotor side at both sides of the top end of the top-separated tooth part. The stator core includes a back yoke, plural teeth, plural partially-connected parts and plural open parts. Each partially-connected part is formed of plural top magnetic path parts and top open parts, which extend in an axial direction. Each open part is formed of only the plural top open parts, which extend continuously in the axial direction.

Abstract: Each permanent magnet provided in a rotor includes a projection that projects toward a corresponding predetermined portion of the rotor core. An inner peripheral surface of each permanent magnet, which is radially opposed to the corresponding predetermined portion of the rotor core, includes a primary contacting portion and two primary non-contacting portions. The primary contacting portion contacts the corresponding predetermined portion of the rotor core at a circumferential location, which corresponds to the projection. The primary non-contacting portions do not contact the rotor core and are located on two circumferentially opposite sides, respectively, of the primary contacting portion.
