Abstract
Official abstract text for this publication.
A stator includes a stator core and a plurality of coils. The stator core includes a core-back, a plurality of teeth portions, and a plurality of lug portions. Each of the plurality of teeth portions includes a coil winding portion and a tip end portion. The core-back includes a slanted portion. An axial position of a magnetic center of the rotor magnet radially outward of the stator overlaps with an axially extending range of the tip end portion. A thickness of the slanted portion in a direction perpendicular or substantially perpendicular to an upper surface of the slanted portion is smaller than an axial thickness of the coil winding portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A motor, comprising: a stationary portion; a rotary portion including a rotor magnet; and a bearing mechanism supporting the rotary portion so as to rotate with respect to the stationary portion about a center axis extending in an up-down direction; wherein the stationary portion includes a stator positioned radially inward of the rotor magnet, a base portion positioned below the stator and a stator fixing portion defined in a cylindrical or substantia…
