    摘要： An insulator (10) includes: an annular outer peripheral portion (11); and a wound portion (50) which extends in a first direction that is a direction from the outer peripheral portion (11) toward a center of the outer peripheral portion and around which a wire (42) is wound. The wound portion (50) includes: an introduction portion (52) to which the wire (42) is introduced from the outer peripheral portion (11); an extend-around portion (51) around which the wire (42) introduced from the introduction portion (52) extends; and an isolation wall (60) which is located between the introduction portion (52) and the extend-around portion (51) in the first direction and by which an introduced portion of the wire (42) which is introduced at the introduction portion (52) and a first-turn portion of the wire (42) which is wound around the extend-around portion (51) are isolated from each other.

    摘要： A motor includes three-phase coils formed of coils of different phases and including a first coil end (61) and a second coil end (71) arranged side by side in a circumferential direction of a stator core (21). The first coil end (61) and the second coil end (71) have a first facing portion (62) and a second facing portion (72), respectively. The motor includes an interphase insulator (51) provided only on the first facing portion (62) among the first facing portion (62) and the second facing portion (72). Each of the first coil end (61) and the second coil end (71) is formed of a plurality of coils of the same phase that protrude onto an end face (26) from a plurality of slots (24) arranged side by side continuously in the circumferential direction of the stator core (21). The first facing portion (62) corresponds to all of the plurality of coils forming the first coil end (61), and the second facing portion (72) corresponds to all of the coils forming the second coil end (71).
