The disclosure relates to a wiring configuration for a stator of an electric machine. The wiring configuration comprises a busbar which forms a segment of a switching ring with an outer connection and a winding connection. Outer connection elements and winding connection elements are arranged in a wiring region. The wiring configuration additionally comprises a receiving element which is at least thermally coupled to the busbar. The receiving element is arranged outside of the wiring region. The disclosure additionally relates to a temperature sensor device for plugging onto the receiving element of the wiring configuration and to a system for detecting the temperature of a stator.

The present disclosure relates to an interconnection assembly for a stator of an electrical machine. The interconnection assembly comprises a shaped bus bar, which has a first region, which comprises a connection point of the interconnection assembly for an external connection, a second region, in which a connecting point for forming a connection of the bus bar to a stator winding is formed, and a central region, which connects the first region and the second region. The first region and the second region are arranged in parallel planes. The central region is oriented in such a way that an angle of a transition between the first region and the central region and an angle of a transition between the second region and the central region deviate from a right angle. The disclosure also relates to a stator having an interconnection assembly.

The invention relates to a stator (IO) in an electric machine (I) with a laminated core (II) formed in an annular fashion about a central axis (A), on which core stator coils () with coil ends () are arranged by means of formers (). The stator (IO) comprises wiring device (), on which a plurality of mutually isolated connecting conductors (-) with coil connection areas (-) are present for connecting the stator coils (). The wiring device () is joined on the stator in an axial joining direction to the stator coils () and is secured by axial connection means () to the formers (), thus forming a plurality of axial connections (). According to the invention, to increase the stiffness of the stator (IO), radial supporting means () are additionally formed on the wiring device () to interact with the formers (), said means being designed to be functionally independent of the axial connection means ().

A coil with a distributed winding formed from hairpins that each have two straight-line conductor portions arranged in different slots of a coil body. Contact regions shaped in circumferential direction adjoin the conductor portions at one axial end and are connected at the other axial end through a turning region. The contact regions have at the end remote of the coil body a connection portion that are aligned in radially extending rows. The contact regions of a layer are shaped in the same circumferential direction. A portion of the contact regions of an outer layer is deformed in radial direction to form an additional, and these contact regions are shaped in a circumferential direction opposite to the contact regions of the outer layer.

Coil with a hairpin winding and method for producing said coil

An electric machine has a plurality of phases. A winding is associated with each phase. An interconnection arrangement includes an annular carrier element with a plurality of axial cutouts, each for passage of a portion of a winding and a plurality of concentrically arranged, hollow-cylindrical switching rings. Each switching ring is adapted to contact a winding. The carrier element and the switching rings are adapted to radially positively engage one inside the other in an axial contact zone.

An insulating unit for an electric machine with hairpin winding. The hairpin winding has a plurality of connection pins for electrically connecting to an interconnect and a plurality of welded hairpin ends. A base body is provided having an insulating material and extends at least over a portion of the circumference of the hairpin winding. The base body has a receiving area which faces the hairpin winding and which has openings for receiving the hairpin ends. The dividing walls are provided between the openings in circumferential direction, and the openings and/or dividing walls have fasteners for engaging connection to the hairpin ends.

Insulating unit for an electric 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.

Stator interconnection device for a rotating electric machine

A stator of an electric machine has an annular stator lamination stack at which stator coils with coil ends are arranged by winding bodies and are connected to an interconnection device arranged at the stator lamination stack on the front side. The interconnection device () is fixed to the stator coils by a carrier element and has connection conductors arranged coaxial to one another that are electrically insulated from one another by insulating layers and carried by the carrier element. Coil connection areas and power connection areas are provided at the connection conductors. The carrier element is formed by one of the connection conductors and/or by a disk-shaped insulating layer and that the connection conductors and the further insulating layers are fixed to the carrier element.
