STATOR INTERCONNECTION DEVICE FOR A ROTATING ELECTRICAL MACHINE

An interconnection device for a stator winding having connection conductors constructed as annular disks, coaxially stacked, and electrically insulated with respect to one another. Each connection conductor has fastening openings distributed in circumferential direction for fixing the interconnection device to a stator. The connection conductors are stacked such that the fastening openings are positioned to form a fastening passage The connection conductors are axially spaced apart from one another and are overmolded with a plastic to form a metal/plastic composite part. At least two kinds of fastening openings are provided, which form larger fastening openings and smaller fastening openings. A larger fastening opening and a smaller fastening opening are formed at a fastening passage, and an annular space, which extends from a boundary of the larger fastening opening to a boundary of the smaller fastening opening, is filled by the plastic.
