Abstract
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.
