Definitions
- the present invention relates to a stator of an electric machine having a stator coil interconnection device according to the preamble of claim 1 and to an electric machine having such a stator according to claim 10.
- a generic stator is known from EP 1 184 957 B1, in which an interconnecting device with a plurality of concentric and axially staggered connecting conductors is arranged axially adjacent to stator coils and fastened to winding bodies of these stator coils by means of a connecting holder serving as a carrier element.
- the connection conductors are mutually electrically isolated by insulating layers arranged in a trough-shaped support element there.
- the coil ends protrude axially from the coils and are connected to connection regions, which respectively protrude from the connection conductors and are led out to a radially outer peripheral region of the interconnection device.
- the invention has for its object to provide a stator of an electrical machine of the type mentioned and an electric machine with a space-saving and cost-effective interconnection device for the stator coils.
- Stator laminated proposed on which by means of winding bodies a number of stator coils with coil ends is arranged, which with a front side on
- the Ver- Circuit device is fixed by means of a carrier element to the stator coils and has a plurality of coaxially arranged connection conductors, which are electrically insulated from each other by means of several insulating layers and are supported by the carrier element. Coil connection regions for the coil ends and power connection regions for the power supply of the electrical machine are provided at the connection conductors.
- the proposed stator is characterized in particular by the fact that the carrier element is formed by one of the connecting conductors and / or by a disk-shaped insulating layer and that the further connecting conductors and the further insulating layers are fixed to the carrier element.
- the carrier element can therefore be formed by a connecting conductor or by an insulating layer or by a carrier element and an insulating layer, in particular adjacent to this carrier element.
- An insulating layer acting as a carrier element does not simultaneously form the two outer insulating layers of the interconnecting device, as is the case with a trough-shaped carrier element for the connecting conductors which is known in the prior art. Serving as a carrier element insulating layer is thus only in contact with one or two adjacent connecting conductors.
- the connecting conductors and insulating layers which do not serve as carrier element can be dimensioned smaller relative to the carrier element, that is to say in particular have a smaller radial extent.
- the insulating layers can be present as separate insulating disks or as one or both sides of a connecting conductor molded coating. In particular, in the case of a molded coating, at least only the coil connection regions and the power connection regions can be exposed. If required to increase the dielectric strength, this covering can also enclose an inner or outer peripheral surface of a connecting conductor. If the carrier element is provided by an insulating layer, at least this insulating layer can be made load-bearing and advantageously made of a suitable plastic.
- the other insulating layers can al- ternatively with a material thickness reduced relative to the carrier element and also from another insulating material, for example from a paper or from a film, in particular self-adhesive.
- the mutual connection of the insulating layers and the connecting conductor and the connection with the carrier element can be effected by separate or by one piece, in particular with the insulating layers connecting means.
- plastic pins may be formed on at least one optional insulating layer, on which the connecting conductor and the other insulating layers can be plugged by means provided there receiving openings.
- separate plastic pins, pins, rivets, etc. may be used.
- An axial securing of the arrangement can take place, for example, by ultrasonic welding or by hot-setting the plastic pins.
- the inner and / or outer circumferential areas of these elements can be designed to enable a mutual positive connection.
- the connecting conductors located on both sides of the carrier element can thus be adapted to existing smaller installation spaces on the stator or within a housing of the electrical machine, which leads to an overall compact arrangement of the stator.
- the connecting conductors and the insulating layers can be formed annular disk-shaped and arranged axially staggered on or to the stator.
- the connecting conductors and insulating layers may also be annular and arranged radially staggered on or to the stator.
- the carrier element of the interconnection device can be fixed directly to the winding bodies or else to a stator carrier or to an element fixedly connected to the stator carrier, for example a housing, depending on the space available concretely.
- a winding body may have a winding region which is formed by a winding support and two legs bounding the winding region in the axial direction and connected to the winding support, wherein the connecting conductors are arranged axially or radially to the winding region.
- the carrier element can be fixed at least on one of said legs or on both legs.
- the winding bodies are usually made of a, in particular injection-moldable plastic, so that can easily form corresponding receiving areas in the form of retaining clips, snap-in connections, grooves, projections, etc. on the legs. As receiving areas can serve to cooperate with the support member, for example in the axial direction of the winding body protruding pins or pins on which the interconnection device can be placed with the support element and which are held by a subsequent thermal deformation permanent and captive there.
- the interconnection device can advantageously be arranged axially adjacent to the winding region of the stator coils.
- one or more connecting conductors can protrude at least partially into the winding region or be absorbed by it.
- the coil ends can be led out radially from the winding bodies and can be arranged axially immediately adjacent to the coil connection areas.
- the coil ends with respect to the coil connection areas can be located on the same axial side as the winding areas. Passing through the coil ends by the Verschaltungsseinnchtung or crossing the coil ends with the connecting conductors is thus not required, which greatly simplifies the assembly of the assembly.
- the present invention further relates to an electric machine having a rotor and a stator, the stator having at least one feature as explained above.
- Fig. 1 is a schematic representation of an electrical machine with a stator and a Verschaltungsseignchtung;
- Fig. 3 is a partial axial section of a stator with a winding on of

- the rotor 14 comprises a cup-shaped rotor carrier 18, On the cylindrical Au (7) Commonsf lache lameli Arthurs rotor core 20 is arranged, which carries a plurality of mutually spaced circumferentially permanent magnets 22.
- the stator 16 comprises an annular stator carrier 24, in the central recess of which an annular stator lamination stack 26 likewise formed from laminations is arranged.
- the axis of rotation A thus forms at the same time the central axis A of the stator.
- the stator support 24 may, for example, constitute an outer or an intermediate housing of the electric machine 10.
- the laminated stator core 26 comprises an annular stator yoke 30, which bears against the stator carrier 24 and has teeth 32 projecting radially inwards from the latter and which is equipped with a plurality of stator coils 36 to form a stator winding.
- These stator coils 36 are wound with the help of two, consisting of a heat-resistant plastic insulating or bobbins 40, 42 of a copper wire around the teeth 32 and secured there against slipping.
- the bobbins 40, 42 each include a front side on the laminated core 26 adjacent base region or winding support 40a; 42a and two of them approximately at right angles and on the stator 16 axially projecting leg 40b, c; 42b, c, which define a winding region 43 in the radial direction.
- the coils 36 are electrically associated with individual strands, to which the coil ends 36a, b are interconnected by means of a in Fig. 1 only schematically shown as a block and axially to the winding portions 43 of the coils 36 interconnecting device 38 in a predetermined manner.
- the interconnecting device 38 for this purpose comprises three interconnecting conductors 52, 54, 56 which are mutually insulated by insulating layers 58a-d and which have coil terminal regions 521, 55 which are circumferentially spaced apart for contacting with the coil ends 36a, b. 541, 561.
- the interconnecting device 38 is fixed to the winding bodies 40 by means of a carrier element 38a, as will be explained in more detail and recognizable on the basis of the further figures.
- the carrier element 38a is formed by the connecting conductor 52 closest to the winding regions 43 and by a disk-shaped insulating layer 58a which bears against the connecting conductor 52 and faces the winding regions 43.
- the further connecting conductors 54, 56 and the further insulating layers 58b-d are fixed to the carrier element 38a by means of connecting elements 59, as will be explained in greater detail hereinafter with reference to FIG. 4.
- the interconnecting device 38 is further connected to the connecting conductors 52, 54, 56 radially outwardly provided power connection areas 52c, 54c, 56c (Fig. 2a) and by connecting conductors 60a-c or alternatively directly to a power electronics 39a and a control electronics 39b with an electrical energy source 39c connected (Fig. 1), which can apply to the operation of the electric machine 10, the winding with a variable-phase current and amplitude.
- the power connection areas 52c, 54c, 56c are designed as flags projecting out of the viewing plane, of which only the associated insulating layers 58 can be seen in FIG. 2a.
- the connecting conductors 52-56 are produced from a copper semi-finished product, in particular from a copper plate or a copper sheet by means of a stamping process or the like as annular discs. These washers are each with intermediate and with two other, the end faces or flat surfaces covering insulating layers 58a-d arranged on the stator 16 coaxial with the central axis A and axially stacked.
- the coil terminal portions 521, 541; 561 are formed as inner radial extensions on the annular disk-shaped connecting conductors 52, 54, 56 and bent axially in the direction of the coils 36 so that they are ready in a common plane for shading with the coil ends 36a, b.
- the coil ends 36a, b are not brought out axially but in the present case radially out of the winding bodies 40, so that they are arranged axially directly adjacent to the coil connection regions 521, 541, 561 and contacted with them can be.
- the coil ends 36a, b are located with respect to the coil terminal portions 521, 541; 561 on the same axial side as the winding portions 43.
- the interconnection device 38 is arranged and fixed on the stator in this embodiment, while the coil ends 36a, b are already for contacting with the coil terminal regions 521, 541; 561 are ready and substantially no further deformation or position change of both the coil terminal portions 521, 541; 561 and the coil ends 36a, b is required.
- Fig. 3 the illustrated arrangement is exemplified at a coil end 36a.
- the coil terminal portions 521, 541; 561 and the coil ends 36a, b thus protrude radially inward beyond the stator teeth 32 and are arranged axially adjacent to the rotor 14 with a view to the general structure of the electrical machine 10 according to FIG.

- the insulating layers are in FIGS. 2-4 as well as the connecting conductors 52, 54, 56 formed as a single flat annular discs.
- the connection conductors 52-56 may also be coated or overmoulded with a plastic to form an insulating layer 58, covering both end faces and the radially inner and outer peripheral surfaces of a connection conductor 52-56.
- the radial extension of an insulating layer 58 may correspond approximately to the radial extent of an associated connection conductor 52-56. At the radially inner or radially outer edge regions of the connecting conductors 52-56, electrical voltage breakdowns and thus undesirable short circuits may occur under certain circumstances. To increase the dielectric strength, an air gap and creepage distance of the connecting conductors 52-56, which are at a different electrical potential, can be increased by extending an insulating layer 58 assigned to a connecting conductor 52-56 beyond a radially inner and / or radially outer edge region and thus via the connecting conductor 52-56 protrudes, as can be seen in the Fig.2,3.
- the supernatant of an insulating layer 58 is dependent on the design of the electric machine 10 and the required clearance and creepage distances and, for example, for a stator of an electric drive driving motor about 0.5 - about 5 mm, preferably about 2 - 3 mm.
- connection conductor 52 a plurality of circumferentially distributed and overlapping common attachment portions 62 in the form of recesses are provided on the connection conductor 52 and on the insulating layer 58a for attachment to the two legs 40b, c of the winding body 40.
- receiving portions 40d, f are formed in the form of axially projecting pins, which receive the interconnecting device 38 and fix it in the occupied position by subsequent hot caulking.
- the connection conductors 52-56 are thus arranged axially relative to a winding region 43.
- FIGS. 4a-e show a plurality of arrangement variants of a switching device 38 with a carrier element 38a which has a greater radial extent than the other elements, which, however, is by no means absolutely necessary.
- three connection conductors 52- 56 are provided, which are provided by a plurality of here on the insulating layer 58c manufactured as a plastic part and formed there as connecting elements 59 formed as axial pins and are fixed in their position.
- insulating layers 58 are present, wherein the outer insulating layer 58d is formed as a support member 38a. According to the representation of FIG.
- an insulating layer 58b located between two connecting conductors can likewise serve as the carrier element 38a of the interconnecting device 38.
- FIG. 4b only two inner insulating layers 58b, c are provided in FIG. 4c, whereas the outer insulating layers 58a, d are omitted.
- the outer insulating layer 58d and the connecting conductor 56 together form the carrier element 38, which corresponds in mirror image, but in principle corresponds to the arrangement shown in FIGS. 2, 3.
- Fig. 4e a basically just such arrangement with the omission of the outer insulating layers 58a, d shown.
- connection conductors 52-56 and also the adjacent insulating layers 58 can be designed with an electrical conductor cross section tapering from the power connection regions in the circumferential direction to the coil connection regions.
