Abstract: A motor includes a stator and a rotor provided inside the stator. The rotor includes a rotor core having a magnet insertion hole and two permanent magnets disposed in the magnet insertion hole. The rotor core has a first magnet holding portion disposed between the two permanent magnets and holding the two permanent magnets, an opening disposed on an inner side of the first magnet holding portion in a radial direction of the rotor core, and a center hole disposed at a center of the rotor core in the radial direction. A distance from the opening to the magnet insertion hole is shorter than a distance from the opening to the center hole.

Abstract: The rotation of the synchronous reluctance motor is controlled through energization of the winding with current of a phase having a ratio k between the total sum of radial-direction widths of the slits on the q-axis and a magnetic gap length, and having a lead angle β from the d-axis. Among the core layers, the radial-direction width, on the q-axis, of the core layer that lies at a position closest in the circumferential direction to a point P at which there intersect the outer periphery of the rotor and the straight line passing through the rotor center and drawn at an angle ψ=arctan(tan β/(1+0.2k)) from the d-axis, is larger than the radial-direction width of other core layers on the q-axis.

Abstract: A compressor equipped with an electric motor having a stator including a stator core, coils, and a string. The stator core is formed of laminated core plates and has crimped portions in boundaries between a yoke and bases of teeth. The crimped portions are spaced at equal intervals in a circumferential direction of the stator core. Coil ends are laced by the string in such a way that the string is not passed through teeth spaces having the crimped portions disposed outward thereof in a radial direction of the stator core, but passed through the teeth spaces that are located adjacently on opposite sides of each of the teeth spaces having the crimped portions disposed radially outward thereof and also passed through at least one of any two adjacent of the teeth spaces.

Abstract: In a method for manufacturing a rotor, each magnetic steel sheet has protrusions on its one surface and has recesses on the other surface at positions corresponding to the protrusions. The plurality of magnetic steel sheets are joined together as the protrusions of each magnetic steel sheet are fitted in the recesses of its adjoining magnetic steel sheet. A shaft member is inserted into a rotor core in the same direction as that in which the protrusions protrude.

Abstract: A rotor (1) for a rotary electric machine includes a rotor core (2) including a first core portion (20) having a plurality of core pieces (5, 6) joined together through caulking portions (2a) and a hollow first lightening portion (20a), and a second core portion (21) having a plurality of core pieces (7, 8) joined together through caulking portions (2a) and a press-fit portion (21b). A radial magnetic path width of a ring-shaped outer circumferential portion formed by laminating the first core portion (20) and the second core portion (21) changes along a circumferential direction of the rotor core (2). Therefore, a weight and an inertia can be reduced.
