Abstract
A stator core of a motor includes a disk portion and a pole-tooth yoke. The disk portion has a disk shape that extends in a radial direction around a central axis extending in a vertical direction. The pole-tooth yoke is located along a radially outer end of the disk portion. The pole-tooth yoke includes an annular portion and a pole tooth. The annular portion is connected to the radially outer end of the disk portion and extends in a circumferential direction. The pole tooth protrudes to one axial side from the annular portion. The disk portion and the pole-tooth yoke are defined by different members.
