In a method of forming a stator for a stepping motor, the present invention first performs the cutting and bending process for forming comb teeth (16) by cutting a flat section (12) of a plate formed with a cylindrical section (14) around the flat portion (12) and bending the comb teeth (16) up to a first angle. Next, in the bending and thickness reducing process, the comb teeth are bent up to a second angle larger than the first angle and the thicknesses of the comb teeth are reduced so as to be uniform. Then, the first drawing process is performed to draw the cylindrical section at least one time. Finally, in the bending process, the comb teeth are bent up to a right angle. Thereby, the occurrence of cambers of the comb teeth and inclinations of comb teeth in the peripheral direction can be inhibited. Also, the squareness of the comb teeth can be improved. <IMAGE> |
