Abstract: A stator for a rotating electric machine includes a stator core and a stator coil. The stator core is formed of a band-shaped steel sheet that is helically bent and laminated. The stator core has slots each opening at an inner periphery of the stator core and spaced from one another in a circumferential direction. The stator coil is formed of electrical conductor segments that are inserted in the slots of the stator core and connected with one another. The band-shaped steel sheet has slits each of which is formed, at a position corresponding to one of the slots, to be open to the corresponding slot. Each of the electrical conductor segments is substantially U-shaped and has a pair of leg portions respectively inserted in corresponding two of the slots of the stator core; the corresponding two slots are circumferentially apart from each other by two or more slot-pitches.

Abstract: A molding process includes forming a primary molded product having interlocking projections and holes in a primary mold. The product is transferred into a secondary mold having interlocking grooves and pins, and secured therein by the engagement of the projections and holes of the product with the grooves and pins, respectively, of the secondary mold. A secondary molded product containing the primary molded product as an insert is formed without having any undesirable displacement of the insert caused by the injection of a molding material at a high pressure. An appropriate molding apparatus is also disclosed.
