Summary: | To improve environmental resistance of a stator.SOLUTION: A blower comprises: an impeller 400 which is rotatable a wind part 401 as a center of an axial direction; and a motor 300 rotatably driving the impeller. The motor comprises: a rotor 1 which can be rotated as the center of a center axis CA; and a stator 2 which rotatably drives the rotor. The stator comprises: a stator core 21; an insulator 22 covering the stator core; and a resin part 25 covering the stator core and the insulator. The stator core includes an annular core back as the center of the central axis; and a plurality of teeth extending to a radial direction one side from the core back. The insulator includes a projection part 3 projected to the radial direction one side from the stator core in at least an axial direction one direction side of the stator core. At least one part of a side surface in the radial direction one side of the projection part is one part of a surface of the stator.SELECTED DRAWING: Figure 1
【課題】ステータの耐環境性を向上させる。【解決手段】送風装置は、軸方向を中心にして翼部401を回転可能なインペラ400と、インペラを回転駆動するモータ300と、を備える。モータは、中心軸CAを中心にして回転可能なロータ1と、ロータを回転駆動するステータ2と、を備える。ステータは、ステータコア21と、ステータコアを覆うインシュレータ22と、ステータコア及びインシュレータを覆う樹脂部25と、を備える。ステータコアは、中心軸を中心とする環状のコアバックと、コアバックから径方向一方側に延びる複数のティースと、を有する。インシュレータは、ステータコアの少なくとも軸方向一方側においてステータコアよりも径方向一方側に突出する突出部3を有する。突出部の径方向一方側における側面の少なくとも一部は、ステータの表面の一部である。【選択図】図1 |
