    摘要: A rotor (10) for a rotary electric machine has a plurality of magnetic poles (24) provided at intervals, in a circumferential direction, at the outer periphery of a rotor core (12). Each of the magnetic poles (24) has a first permanent magnet (26) buried in the center of the magnetic pole, and a pair of second permanent magnets (28) that are buried on both sides of the first permanent magnet (26) in the circumferential direction, and that are disposed such that a mutual spacing between the pair of the second permanent magnets (28) becomes narrower inward in the radial direction. A narrowest spacing between the pair of second permanent magnets (28) is set to be wider than a longitudinal-direction width of the first permanent magnet (26) in a magnetic path region (30) that is defined by the first permanent magnet (26) and the pair of second permanent magnets (28).

    摘要: In a rotor for a rotary electric machine, a plurality of magnetic poles are provided in a radially outer portion of the rotor iron core, at intervals in the circumferential direction. Each magnetic pole includes a pair of permanent magnets disposed apart from each other in the circumferential direction, and a magnetic flux-restraining hole that is formed and extended radially inwardly between radially inner end portions of the permanent magnets and that restrains flow of magnetic flux. The magnetic flux-restraining hole is extended so as to project beyond a position of the radially inner end portions to a radially outer side, between the pair of permanent magnets.

    摘要: A rotary electric machine configured with a stator, rotor, and permanent magnets disposed in an inverted V-shape that becomes gradually narrower from a side of a center of rotation of the rotor. The rotor is provided with a plurality of support portions that extend radially about the center of rotation, and gap portions are respectively formed in correspondence with the plurality of support portions at positions spaced by a predetermined distance from an edge portion of the permanent magnets in a flowing direction of magnetic flux between the permanent magnets and the stator. The gap portions are formed to have such a length that causes magnetic saturation during generation of low torque in a low-current state and that causes no magnetic saturation during generation of maximum torque in a high-current state in which electricity at a high current is supplied to the stator coil.
