Method for manufacturing a stator of a stepping motor |
摘要 |
<p>A method for manufacturing a stator of a stepping motor comprises the steps of carrying out a half-pierce and push-back process to a frame plate (10) to make an area in which comb teeth (16) are to be formed and an area to be blanked out readily separable, carrying out a blanking process to separate the blanked piece (20) from the comb teeth (16), bending the comb teeth to a predetermined angle and collapsing the comb teeth to make the thicknesses of the comb teeth uniform; and bending the comb teeth at right angle to an outer periphery of the frame piece. <IMAGE></p> |
