Abstract
A radial-winding stator of a motor including a core and eight poles is disclosed. Each pole has a magnetic pole and a pole piece. The magnetic pole is connected to the core and extends outwards from the core in a radial direction. The pole piece is formed at one end of the magnetic pole distant to the core. The pole piece includes a magnetic end face having an arc length along a circumferential direction of the core, as well as an axial height along an axial direction perpendicular to the radial direction. A ratio of the arc length to the axial height is between 2.05 and 10. In another embodiment, the radial-winding stator includes ten or twelve poles.
