Definitions

  • the present invention has been made to solve the above problems, while suppressing the unevenness of the heat conductive material filled in the winding, it is possible to increase the impregnated amount of the heat conductive material, the stator and
  • An object of the present invention is to provide a compressor provided with the stator.
  • a lower insulator disposed on a lower end surface in the axial direction, wherein the upper insulator and the lower insulator cover a top surface of the tooth portion, and a body portion around which the winding is wound, and an outer portion of the body portion.
  • a plate-like first flange portion provided at a radial end portion, protruding from the body portion in the axial direction of the stator core and extending left and right along the circumferential direction, and an inner diameter side end of the body portion.
  • a plate-shaped second flange portion that is provided on the body portion, projects from the body portion in the axial direction of the stator core, and extends to the left and right along the circumferential direction, and the winding of the body portion.
  • the stator 4 includes a stator core 6, a winding 7, and an insulator 8.
  • the stator core 6 is formed by stacking a plurality of electromagnetic steel plates punched out into a substantially T-shape when viewed two-dimensionally.
  • the electromagnetic steel sheet is made of, for example, a silicon steel sheet.
  • the stator core 6 includes a plurality of split cores 60 each having a core back portion 6a extending in the circumferential direction and a plurality of teeth portions 6b extending inward from the core back portion 6a and arranged in an annular shape. It is formed by rotatably connecting 60. As shown in FIG.
  • the winding wire 7 is not limited to an aluminum wire, and may be a copper wire, for example. Since the copper wire has a higher hardness than the aluminum wire, it has low adhesion, and when used as the winding wire 7, the varnish, which is a heat conductive material, easily penetrates.
  • the second flange portion 80c covers the tip portion of the tooth portion 6b, as shown in FIGS. 3 to 5.
  • a fourth groove portion 85 continuous with the first groove portion 82 is formed in the axial direction from the projecting upper end portion toward the body portion 80a.
  • the heat-conducting material is poured from the fourth groove portion 85 and guided to the first groove portion 82, so that the heat conducting material is mainly filled in the inner diameter side of the winding 7.
  • the fourth groove portion 85 is preferably provided because it can enhance the effect of filling the inner diameter side of the winding 7 with the heat conductive material, but may be omitted.
  • the winding wire 7 is an aluminum wire. Since the aluminum wire is lower in cost than the copper wire, for example, it can contribute to the reduction of the manufacturing cost of the stator 4. On the other hand, since the aluminum wire has a higher non-resistivity than the copper wire, the generated Joule heat is large and the temperature tends to rise. Moreover, the hardness of the aluminum wire is lower than that of the copper wire, and the adhesion between the windings is increased due to the tension at the time of winding, so that the varnish that is a heat conductive material hardly penetrates.
  • the third groove portions 84 may be formed one by one with the second groove portion 83 interposed therebetween as shown in FIG. In this case, the third groove portion 84 is formed wide along the circumferential direction.

Abstract

La présente invention concerne un stator pourvu d'un noyau de stator, d'un enroulement, et d'un isolant. L'isolant comprend un isolant supérieur et un isolant inférieur. L'isolant supérieur et l'isolant inférieur ont chacun une partie de corps, une première partie de bride disposée au niveau de la partie d'extrémité de la partie de corps sur le côté radial externe, et une seconde partie de bride disposée au niveau de la partie d'extrémité de la partie de corps sur le côté radial interne. Une première partie de rainure est formée sur une surface faisant face à l'enroulement autour de la partie de corps le long de la direction radiale. Une deuxième partie de rainure continue à la première partie de rainure est formée sur la surface de la première partie de bride sur le côté radial interne à partir de la partie d'extrémité vers la direction axiale, et une troisième partie de rainure est formée qui est parallèle à la deuxième partie de rainure et s'étend de la partie d'extrémité vers une partie de fente disposée entre des parties de dent adjacentes.
