The stator portion includes a stator core and coils. The outside surface extends in an axial direction parallel or substantially parallel to a central axis, and is centered on the central axis. The spindle motor includes a fixing portion at which an inside surface of the stator core and the outside surface are fixed to each other. The fixing portion includes a first press fit portion, a second press fit portion, and a gap arranged therein. The gap is located between the first press fit portion and the second press fit portion. The second press fit portion is located above the first press fit portion. At least a portion of the second press fit portion is located above a middle of the stator core in the axial direction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spindle motor and disk drive apparatus","description":"A stationary portion of a spindle motor includes a stator portion and an outside surface.
