Abstract:
A stator comprising:a bobbin having an axial winding wound therearound; plural single pole plates each having a pole end, each said single pole end having a single pole face extending from the pole end; an axle tube extending through the bobbin and said plural single pole plates, the axle tube conducting magnetic flux created by the winding to said plural single pole plates; a half of said plural single pole plates being stacked and mounted on top of the bobbin and another half of said plural single pole plates being stacked and mounted to a bottom of the bobbin, the number of the half of said plural single pole plates mounted on top of the bobbin being not less than two, the number of the half of said plural single pole plates mounted to the bottom of the bobbin being not less than two, thereby increasing magnetization, reducing magnetic flux leakage, and gaining effectively guided overall magnetic flux by means of increasing an overall thickness for effectively conducting the magnetic flux to said plural single pole plates.
