摘要： Coil members are obtained by forming width-reduced portions in a wire material over a predetermined longitudinal range generally centered on cutting positions, then removing an insulation coating from the width-reduced portions, and thereafter cutting the wire material at the width-reduced portions. Coil segments are prepared by bending the coil members into a general U shape. Then the coil segments are inserted into the slots in a stator core, and a stator is obtained by welding together the free end portions of the projecting coil segments.
