Abstract
A stator core has a plurality of slots. Insulating members are formed into a cylindrical shape and are inserted into the slots. Axial ends of the insulating members are expanded respectively and deformation marks thinner than the other portion are formed respectively. Then, the insulating members are moved toward the expanded ends to position the deformation marks in the out of the slots. After that, the conductors are inserted into the slots from the expanded side of the insulating members. Therefore, insulation failure at the portions of the deformation marks is prevented.
