发明名称 Electrical rotating machine
摘要 An electrical rotating machine includes: a rotating shaft; a rotor, equipped with permanent magnets, and formed to rotate with the rotating shaft, a stator disposed in opposition on an outside-diametral side and via a clearance with respect to the rotor; and anti-demagnetization conductors extending in the axial direction of the shaft, the conductors each being disposed inside the rotor, wherein: the anti-demagnetization conductors are provided in pairs of two for each of magnetic poles of the rotor; the two anti-demagnetization conductors forming a pair are electrically interconnected; and, inside the rotor, the two paired anti-demagnetization conductors are disposed at different-polarity sides of two corresponding permanent magnets in a circumferential direction of the rotor, the different-polarity sides each being more adjacent to the circumferential direction of the rotor than to an end portion of one of the two corresponding permanent magnets existing close to each other in one magnetic pole.

主权项 1. An electrical rotating machine comprising: a rotating shaft; a rotor formed to rotate with rotation of the rotating shaft, the rotor being equipped with permanent magnets; a stator disposed in opposed form on an outside-diametral side of the rotor via a clearance with respect to the rotor; and anti-demagnetization conductors extending in an axial direction of the rotating shaft, the conductors each being disposed inside the rotor, wherein: the anti-demagnetization conductors are provided in pairs of two for each of magnetic poles of the rotor to form a pair of anti-demagnetization conductors; wherein the pair of anti-demagnetization conductors are electrically interconnected; and inside the rotor, the pair of anti-demagnetization conductors are nonuniformly disposed at different-polarity sides of two corresponding permanent magnets in a circumferential direction of the rotor, and are arranged so that one of the pair of anti-demagnetization conductors is more adjacent to the circumference of the rotor than to the permanent magnet.
