Definitions

  • the teeth 4 are made of a magnetic material.
  • the tooth 4 includes a trunk portion 41 , two outer protrusions 42 and two inner protrusions 43 .
  • the tooth 4 has an outer peripheral surface 4a and an inner peripheral surface 4b along the circumferential direction D1. That is, the outer peripheral surface 4 a is the outer surface of the tooth 4 , and the inner peripheral surface 4 b is the inner surface of the tooth 4 .
  • the tooth 4 has an outer side surface 4c and an inner side surface 4d between the outer peripheral surface 4a and the inner peripheral surface 4b. In two adjacent teeth 4, the outer side surfaces 4c are in contact with each other, and a space is formed between the inner side surfaces 4d.
  • the insulator 5 is formed in a box-like shape with both end faces in the radial direction D2 and a lower face opened, and the body portion 41 of the tooth 4 is inserted from the lower face.
  • the insulator 5 includes a first member and a second member. The second member is put on from (bottom) so as to cover the inner side surface 4d of the tooth 4 .
  • the insulator 5 is integrally molded with the teeth 4 .
  • the rotor 2 is arranged inside the stator 3 .
  • the stator 3 may be arranged inside the rotor 2 .
  • the motor 1 is not limited to the inner rotor type, and may be of the outer rotor type.
  • the thin portion 81 and the thin portion 91 may be provided only in the insulating sheet 7 of some of the tooth blocks TB1 among the plurality of tooth blocks TB1. Alternatively, the insulating sheet 7 may be provided with only one of the thin portion 81 and the thin portion 91 .
  • FIG. 5 is a perspective view of the insulating sheet 7A of the stator 3 according to Embodiment 2.
  • FIG. Configurations similar to those of the first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.
  • the possibility that the second portion 8 and the third portion 9 are misaligned can be reduced compared to the first embodiment. Specifically, the possibility that the second portion 8 and the third portion 9 are displaced in the radial direction D2 can be reduced. Also, compared to the first embodiment, the creepage distance (insulation distance) between the two windings 6 of the two tooth blocks TB1 adjacent to each other can be extended. That is, in this embodiment, the creepage distance is extended by the length of the folded portion of the second portion 8 and the third portion 9 . Thereby, the electrical insulation between the two windings 6 can be improved.
  • the first fitting portion (811) and the second fitting portion (911) of the insulating sheets (7, 7A to 7F) are The cross-sectional shape is trapezoidal.
  • the possibility of misalignment between the second portion (8) and the third portion (9) can be reduced. Also, the creepage distance (insulation distance) between the two windings (6) of the two tooth blocks (TB1) adjacent to each other can be extended.
  • a motor (1) according to a twelfth aspect includes a stator (3) according to any one of the first to eleventh aspects and a rotor (2).
  • the rotor (2) has a rotor shaft (21). The rotor (2) rotates relative to the stator (3).
