Rotor and rotating electric machine

A rotating electric machine comprising a stator and a rotor disposed radially inside the stator, wherein

• the rotor includes a plurality of rotor units disposed side by side in an axial direction,
• the plurality of rotor units each include (i) a rotor core and (ii) a plurality of permanent magnets that are embedded in the rotor core and are in a folded shape projecting radially inward,
• the plurality of rotor units each have (i) a plurality of magnetic pole sections that are provided in a circumferential direction and respectively include the plurality of permanent magnets and (ii) a plurality of magnetic pole bordering sections that are boundaries between the plurality of magnetic pole sections,
• the plurality of rotor units each have a plurality of displacement portions in an outer circumferential surface of the rotor core, the plurality of displacement portions being disposed in one-to-one correspondence with the plurality of magnetic pole bordering sections,
• each of the plurality of displacement portions is displaced radially inward from respective magnetic pole centers of a circumferentially adjacent pair of the plurality of magnetic pole sections toward a magnetic pole bordering section of the plurality of magnetic pole bordering sections located between the pair of the magnetic pole sections,
• in rotor units among the plurality of rotor units located at both axial ends of the rotor, the permanent magnets each have a protruding portion protruding from an end surface on a side where no other rotor unit is disposed side by side in the axial direction,
• magnetic pole centers of one of the plurality of rotor units are offset in the circumferential direction with respect to magnetic pole centers of another of the plurality of rotor units adjacent thereto in the axial direction, and
• assuming that p denotes a number of poles of the rotor and L denotes a least common multiple of the number of poles of the rotor and a number of slots of the stator, a skew angle θ [°] is set such that
• (180/L)−16/p≤θ≤(180/L)+36/p
• is satisfied, the skew angle being a circumferential offset angle between the rotor units.
