摘要： In a rotating body (32) of a rotor (30), a plurality of permanent magnets (45) are arranged in a circumferential direction, alternating with a plurality of divided cores (33). The plurality of permanent magnets (45) is in surface contact with side surfaces of the divided cores (33) in the circumferential direction in a state where facing magnetic pole faces of two permanent magnets (45) arranged on both sides of each divided core (33) in the circumferential direction are homopolar. In a resin covering portion (50) of the rotating body (32), a first part (51) and a second part (52) cover end surfaces of the plurality of permanent magnets (45), a plurality of third parts (53) covers outer peripheral surfaces of the plurality of permanent magnets (45), and a fourth part (54) covers inner peripheral surfaces of the plurality of divided cores (33) and inner peripheral surfaces of the plurality of permanent magnets (45). Outer peripheral surfaces of the divided cores (33) are exposed without being covered by the covering portion (50).

摘要： A first portion (61) of an insulator (60) is provided on a first region (R1) of an end surface (S3) of a tooth (35). A second portion (63) of the insulator (60) is provided on a second region (R2) of the end surface (S3) of the tooth (35) so as to be separated from the first portion (61) in a circumferential direction. A third portion (65) of the insulator (60) is connected to fourth side ends of the first portion (61) and the second portion (63) in a radial direction. A coil (50) includes a crossing portion (52) in a coil end (51). A stator (30) includes an insert body (82) in a housing space (SP). The insert (82) is made of a material having a higher thermal conductivity than a material forming the insulator (60).
