Stator with a radial winding

摘要

A stator comprises plural stacked silicon steel plates having aligned axle holes. An auxiliary plate is superimposed on the stacked silicon steel plates and comprises an axle hole aligned with the axle holes of the silicon steel plates. Each silicon steel plate comprises even-numbered radial arms each having a magnetic pole face at a distal end thereof. The auxiliary plate comprises auxiliary radial arms, wherein the auxiliary radial arms and the radial arms of the silicon steel plates are alternately disposed. Form on a distal end of each auxiliary radial arm is a magnetic pole face that extends vertically, the magnetic pole face being appropriately spaced from the magnetic pole faces of the radial arms of the silicon steel plates. The magnetic pole faces of the auxiliary radial arms of the auxiliary plate and the magnetic pole faces of the silicon steel plates have different widths or thicknesses.
