STATOR AND METHOD FOR MANUFACTURING SAME

摘要

In an existing technique, a mechanism for moving a bobbin back and forth when a conductor wire is wound around the bobbin is required, which makes a production apparatus complicated and expensive. Moreover, a process of transferring a coil is required, which increases the number of production processes. A method for producing a stator of a rotating electrical machine includes: a winding process in which a conductor wire is sequentially wound around each of a plurality of winding bases, each being shaped like a projection, multiple times in alignment, the winding bases provided on an outer circumferential surface of a winding jig provided with a cylindrical portion having slits; an attachment process in which the cylindrical portion on which the winding has been performed is fitted into an inside diameter side of a stator core; and a coil movement process in which extension members are inserted into the slits from a central axis side to an outer perimeter side of the cylindrical portion and coils wound around the winding bases are moved to slots of the stator core.
