Abstract
A method for forming a loop winding having a plurality of meandering parts and disposed in a stator of a motor which includes: disposing the loop winding between a first die unit having a plurality of first dies and a second die unit having a plurality of second dies; and press forming the loop winding between the first dies and the second dies by relatively moving the first die unit and the second die unit toward each other, wherein the press forming step is so performed as to provide the loop winding with a plurality of meandering parts and, simultaneously, to reduce the loop winding in the radial direction.
