摘要： A rotating electrical machine includes a rotor which has a rotor core formed by stacking magnetic plates having an annular plate shape in an axial direction, a permanent magnet is inserted into a magnet insertion hole formed in the rotor core, and a rotor shaft is inserted into a shaft insertion hole surrounded by an inner peripheral surface of the rotor core; and a stator. A radial communication passage is formed by a communication penetration hole group that is formed by sequentially communicating a plurality of the penetration holes from a shaft insertion hole to a magnetic resistance hole in the radial direction. The plurality of the penetration holes are divided into at least two specific magnetic plates and formed such that the radial positions of the penetration holes are different from each other and the penetration holes partially overlap each other when viewed in the axial direction.

摘要： An iron rotor core includes a first permanent magnet in an outer peripheral portion of the iron rotor core, second permanent magnets on both circumferential sides of the first permanent magnet and arranged in a generally V-shaped configuration opening radially outward, and a first region provided opposite to the first permanent magnet radially inside the region between the second permanent magnets and having a low magnetic permeability. A q-axis magnetic flux path is formed in an iron core region among the first permanent magnet, the second permanent magnets and the first region, and a central portion thereof is formed between the first permanent magnet and the first region, and entrance/exit portions of the q-axis magnetic flux path formed between the second permanent magnets and second regions provided on both circumferential sides of the first permanent magnet and having a low magnetic permeability with generally the same width.

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.
