Zusammenfassung: | To prevent a surface of a substrate from being covered by resin.SOLUTION: A motor includes a stator, a substrate provided on the stator with wiring, and a resin member covering the stator. In a direction of a rotary shaft, the substrate includes a first surface facing the stator, and a second surface. The first surface of the substrate is in contact with the resin member. The second surface of the substrate includes an inner peripheral portion and an intermediate portion between the inner peripheral portion and an outer edge portion of the substrate. A recess extending in a radial direction is formed on the intermediate portion of the second surface of the substrate. An end portion of an inner peripheral side of the recess is on the outer edge portion in the radial direction with respect to the inner peripheral portion of the second surface.SELECTED DRAWING: Figure 1
【課題】基板の表面が樹脂に覆われることを抑制する。【解決手段】モータは、ステータと、前記ステータに設けられた、配線を有する基板と、前記ステータを覆う樹脂部材と、を備える。回転軸の方向において、前記基板は、前記ステータに対向する第1の面と、第2の面とを備える。前記基板の第1の面は、前記樹脂部材と接触している。前記基板の第2の面は、内周部、及び当該内周部と前記基板の外縁部との間にある中間部を備える。前記基板の第2の面の中間部には、径方向に延在する凹部が形成されており、前記凹部の内周側の端部は、前記第2の面の内周部に対して、径方向において前記外縁部側にある。【選択図】図1 |
