摘要： A rotor for a rotary electric machine has a plurality of magnetic poles provided at intervals in a circumferential direction of a rotor core, at an outer periphery of the rotor core. Each of the magnetic poles includes a central magnet, a pair of circumferential-direction magnets disposed on both sides of the central magnet in the circumferential direction such that a spacing between the pair widens towards an outer periphery of the rotor core, and low permeability regions provided in the vicinity of end portions of the central magnet in the circumferential direction, and having a permeability lower than a magnetic material of the rotor core. The rotor core is formed such that a width of a magnetic path entrance portion that is formed between a magnetic-pole inward side face of the circumferential-direction magnet and the adjacent low permeability region decreases towards an outer peripheral face of the rotor core.

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.
