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： A rotor for a rotary electric machine includes a plurality of magnetic poles disposed at intervals in a circumferential direction, on an outer periphery of a rotor core that is a steel sheet stack that has a shaft hole in a central portion thereof configured so that a shaft is passed through and fixed to the shaft hole. The magnetic poles each have two permanent magnets and a magnetic flux suppression hole that regulates flow of magnetic flux from the permanent magnets, and are formed in such a manner that a shape of the magnetic flux suppression hole of at least one magnetic pole is different from a shape of the magnetic flux suppression hole of another magnetic poles, depending on the presence or absence of a positioning portion.
