    摘要： An insulator according to an embodiment includes a teeth cover portion and a crossover-wire guide portion. The crossover-wire guide portion guides: a crossover-wire portion of a coil drawn out from the teeth cover portion; and an introduction crossover-wire portion of an introduction coil that is drawn out from a second split core different from a first split core attached to the teeth cover portion and is introduced into the crossover-wire guide portion, into a terminal connection portion disposed on a circumference substantially along a ring shape of the stator core. The crossover-wire guide portion has a guide groove that guides the crossover-wire portion and the introduction crossover-wire portion substantially in a core circumferential direction that is a circumferential direction of the stator core. In a state in which the plurality of the split cores are assembled in a ring shape, the guide groove is formed in a shape that does not coincide with a circular arc of a circle having a center corresponding to a ring center of the assembled split cores.

    摘要： In a stator (3), a segment conductor (18) includes a pair of leg portions (20) inserted into slots (15), and a crossover wire portion (21) that couples the pair of leg portions (20). The stator (3) includes an insulator (11a) that includes a winding barrel portion (23) and an insertion portion (26) that are integrally molded. The winding barrel portion (23) is disposed between a stator core (9) and the crossover wire portion (21) of the segment conductor (18). The insertion portion (26) is disposed on an inner side from the leg portions (20) of the segment conductor (18) inside the slots (15) of the stator core (9).

    摘要： A molded motor includes a rotor, a stator facing the rotor, a bearing on which the rotor is rotatably supported, a mold resin portion covering the stator with mold resin, a metal member mounted on an outer surface of the mold resin portion, and an insulating material located between the mold resin portion and the metal member. The rotor has a rotary shaft that extends in an axial direction, and a rotor core that holds a permanent magnet and is fixed to the rotary shaft. The stator includes a stator core on which a plurality of salient poles are arranged in a circumferential direction, and a plurality of coils each wound via an insulator around corresponding one of the salient poles of the stator core. The metal member includes a cylindrical portion having a cylindrical shape, and a bottom surface portion forming a bottom surface of the cylindrical portion. At least a part of a surface of the insulating material is arranged at a portion facing the plurality of coils arranged in the circumferential direction.
