Abstract
A stator assembly includes a stator that drives a rotor rotatable about a central axis extending in a vertical direction, a cover that accommodates the stator, a filling portion that fills a space between the cover and the stator. The cover includes a tubular portion that extends in an axial direction and covers a radially side portion of the stator opposing the rotor in a radial direction, a lid portion that covers an axially upper end portion of the stator, and a cover stepped portion that is provided on a first radial side with respect to the tubular portion. The cover stepped portion comes in contact with the axially upper end portion of the stator and is positioned on an axially lower side with respect to an axially upper end portion of the tubular portion.
