Zusammenfassung:A motor includes a rotary portion including a shaft having a center on a vertically extending central axis. A bearing portion rotatably supports the shaft. A stationary portion includes a stator. The bearing portion is radially outward of the shaft and includes a sleeve bearing that contains a lubricating oil; and a housing radially outward of the sleeve bearing. The stator includes a stator core that is radially outward of the housing; and an insulator that covers at least part of the stator core. The insulator includes an upper insulating portion that covers an upper face of the stator core; a connecting portion that extends radially inward from the upper insulating portion; and an insulator inclined portion that is inclined in a direction away from the central axis, away from the connecting portion.
