Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a stator unit, a motor, and a fan motor capable of improving waterproofness of a stator.SOLUTION: In a fan motor 100, a stator unit 2 of a motor 110 for rotationally driving an impeller 120 includes: an annular stator 20 centered on a central axis CA; and a housing part 24 having a housing part 240 for housing a part of a resin part 22 covering at least a part of the stator 20. On at least one of a bottom surface 240a facing the stator side in an axial direction of the housing part 240 and an inner surface 240b facing inward in a radial direction of the housing portion 240, a step part 241 having a different axial length of the bottom surface 240a or radial length of the inner surface 240b is provided. The bottom surface 240a, the inner surface 240b, and the step part 241 are covered with the resin part 22.SELECTED DRAWING: Figure 1
【課題】ステータの防水性を向上することができるステータユニット、モータ、及びファンモータを提供する。【解決手段】ファンモータ100において、インペラ120を回転駆動するモータ110のステータユニット2は、中心軸CAを中心とする環状のステータ20と、ステータ20の少なくとも一部を覆う樹脂部22の一部を収容する収容部240を有するハウジング部24と、を備える。収容部240の軸方向のステータ側に向く底面240a、及び、収容部240の径方向の内方に向く内側面240bのうちの少なくとも一方の面に、底面240aの軸方向又は内側面240bの径方向の長さが異なる段差部241が設けられる。底面240a、内側面240b、及び段差部241は、樹脂部22で覆われている。【選択図】図1 |
