To determine an axial position of a cover member relative to a stator with high accuracy.SOLUTION: A stator unit 102 includes: a stator 20 which drives a rotor 101 which may rotate around a center axis CA extending in a vertical direction; a cover member 30 which houses the stator 20; and a filling part 50 filling a space between the cover member 30 and the stator 20. The cover member 30 has: a cylinder part 31 which extends in an axial direction and covers a radial side surface part of the stator 20 facing the rotor 101 in a radial direction; a lid part 32 which covers an axial upper end part of the stator 20; and a cover step part 33 provided closer to one side as seen in a radial direction than the cylinder part 31. The cover step part 33 contacts with the axial upper end part of the stator 20 and is located below an axial upper end part of the cylinder part 31 when viewed in the axial direction.SELECTED DRAWING: Figure 3 【課題】ステータに対するカバー部材の軸方向位置を精度良く決定する。【解決手段】ステータユニット１０２は、上下方向に延びる中心軸ＣＡを中心として回転可能なロータ１０１を駆動するステータ２０と、ステータ２０を収容するカバー部材３０と、カバー部材３０とステータ２０との間に充填される充填部５０と、を備える。カバー部材３０は、軸方向に延び、且つ、ロータ１０１と径方向に対向するステータ２０の径方向側面部を覆う筒部３１と、ステータ２０の軸方向上端部を覆う蓋部３２と、筒部３１よりも径方向一方に設けられるカバー段部３３と、を有する。カバー段部３３は、ステータ２０の軸方向上端部と接し、筒部３１の軸方向上端部よりも軸方向下方に位置する。【選択図】図３
