Definitions

  • the invention relates to an electrical machine, comprising a stator with a winding comprising a plurality of conductors assigned to one or more phases, which are interconnected.
  • Electric machines comprising a rotor and a stator are used in a wide variety of applications.
  • the use of electric machines for electric hybrid vehicles and electric vehicles or for hub drives is only mentioned as an example. If such an electrical machine is used as a drive machine, it is mostly designed as an internal rotor, which means that the stator surrounds the internal rotor. A wandering magnetic field is generated via the stator, which causes the rotor to rotate.
  • the stator has a winding consisting of a multiplicity of conductors, the conductors being assigned to one or usually several phases.
  • circumferential conductors To form quasi-meandering, circumferential conductors, they are to be connected accordingly at their ends, which is usually done by welding the conductor ends that are adjacent to one another.
  • the conductor ends converge at one point or one winding side in the form of a so-called star, where they are connected to one another.
  • the connection of the individual phases to an external power supply i.e. a power connection that is used to generate the mag- netfelds is used to do what is often very complicated to implement due to space constraints.
  • the invention is thus based on the problem of specifying an electrical machine that is improved in comparison.
  • the invention provides for an electrical machine of the type mentioned at the outset that the ends of at least two conductors assigned to a phase protrude axially or radially over the winding on the inner circumference and / or on the outer circumference of the winding and with one arranged radially outside the winding Power connection are connected via a common connecting conductor.
  • connection ring is used for the actual connection of the conductors, i.e. a conductor ring that is placed axially on the winding. This engages in the area of the protruding conductor ends, wherein the conductor ends can protrude axially on the inner circumference and / or on the outer circumference of the winding.
  • the conductor ends are the individual conductor sections, unless they are on other, z. B. further inner radial planes are connected to each other, assigned.
  • the conductor ends are connected to the interconnection ring, usually welded accordingly, so that the corresponding phase-specific conductor structures or conductor connections are generated via the interconnection ring.
  • connection conductors are provided according to the invention, which connect the conductors protruding axially over the winding or the winding head, phase-specifically, to the corresponding phase-specific contact areas of the power connection or HV terminal.
  • connection conductors have a certain length after the power connection and thus the corresponding contact areas there and the protruding ends of the stator on the other side are spaced apart due to the separation of the interconnection ring and the power connection.
  • the cross-section of the connecting conductor should be at least twice as large as that of the corresponding single conductors as they have been used up to now or as the winding conductors also have, so that it there is no jump in conductor cross-section at the transition from the conductor ends or the winding to the connecting conductors. If three in-phase conductor ends are connected, the conductor cross-section of the common connecting conductor should be at least three times, etc. This means that the conductor cross-section of the connecting conductor corresponds to at least the total cross-section of the winding-side conductors or conductor ends to be contacted, and is possibly slightly larger.
  • the connecting conductor can have a contact section sen, with which it is only contacted on one side of the two conductor ends.
  • the connec tion conductor is so with its contact section on only one side, for example radially outside, on the corresponding contact sections or surfaces of the conductor ends.
  • the connecting conductor can also have a contact section with which it is contacted on two opposite sides at both conductor ends. This means that there is double-sided contact at the conductor ends, whereby the contact connection is even more secure and, if necessary, also improved with regard to the current carrying capacity.
  • the connection of the conductor ends and the connecting conductor is of course preferably carried out by welding.
  • the connecting conductor can have a contact section which is U-shaped for contact on both sides of the conductor ends.
  • the contact section is designed like a clamp and, due to its U-shape, engages around the two or more conductor ends, so these are received in the U-shaped receptacle and can be welded accordingly ver.
  • the contact section can overall have a U-shaped receptacle encompassing both or more ends. It is thus designed as a U-shaped bracket at the end of the connecting conductor, into which the conductor ends engage.
  • the contact section can have two U-shaped receptacles, each of which encompasses one end of the conductor. So here each end of the conductor is fixed in a common U-shaped bracket.
  • the contact section can be made wider than the actual conductor width, the specific geometry ultimately depending on the distance between the two or more conductor ends to be contacted, which are usually more closely spaced and offset from one another only a short distance around the circumference of the winding.
  • several contact elements corresponding to the number of phases can be provided at the power connection, which contact elements have a wide base and at least two fingers protruding from this.
  • Such a contact element offers the possibility of both connecting a common, wide connecting conductor and, in the event that such a common, wide connecting conductor cannot be used, correspondingly narrower, individual connecting conductors to be connected.
  • the contact element is quasi multifunctional.
  • the wide, common connecting conductor can be connected in the area of the wide base. In the area of the narrower, protruding fingers, there is a narrow connecting conductor in each case, so that regardless of what type or geometry the connecting conductors are, a suitable connection can always be achieved with such a contact element.
  • the ends of at least some of the conductors are preferably protruding beyond the winding, some of these conductor ends being connected to a connection ring placed axially on the winding, the connection conductors being fixed to at least one holding element provided on the connection ring.
  • This configuration with the common interconnection ring enables the meander structure of the conductors to be formed easily via the winding itself.
  • the interconnection ring also serves as a location for fixing the connection conductors. This is because the connecting conductors have a certain length after the power connection and thus the corresponding contact areas on the local side and the protruding winding ends of the stator on the other side are spaced apart due to the separation of the connection ring and the power connection.
  • the invention provides that the connecting conductors are fixed to at least one retaining element provided on the interconnection ring.
  • the connecting conductors are not only connected via their actual contact points, i.e. welded connections to the conductor ends on the one hand and the contact areas on the other hand, but are also fixed over their length to at least one holding element provided on the interconnection ring. This enables a sufficiently rigid connection of the connecting conductor to which, respectively, is inside the machine on the other side the conductor configuration is still flexible enough to be able to compensate for any vibrations in the drive train.
  • the interconnection ring can have a housing on which the Hal teiata or elements are arranged. As described, the interconnection ring includes corresponding separate line bridges. These are preferably accommodated in a housing, preferably made of plastic, so that the interconnection ring can also be configured in advance and only needs to be put on.
  • the cable bridges which are correspondingly stable metal sheets, are geometrically shaped so that they reach the conductor ends to be connected accordingly. They are grouped to the corresponding circuit ring and allow easy bridging of appropriate distances in both circumferential and radial direction. Like the individual conductors and connecting conductors, they are of course insulated from one another. They also have corresponding, preferably radially vorsprin ing connecting sections to which the ends of the conductors that protrude from the winding are welded. These preferably protrude from the housing and enable simple conductor connection.
  • the connecting conductors can have a considerable length and, for example, run around a circumference of up to 90 °, the connecting conductors differ in length, which is why some connecting conductors only on a retaining element, others may also fixed to two or more retaining elements around the circumference who the.
  • the fixing is expediently carried out in such a way that the or each holding element is designed as a latching or clamping element to which one or more connecting conductors are fixed via a latching or clamping connection. This enables the holding elements to be easily connected to the corresponding connecting conductors.
  • the housing of the interconnection ring itself is preferably designed as a plastic housing that is manufactured using a plastic injection molding process.
  • the or each Hal teelement or the or each locking or clamping element is preferably di- Formed right on the plastic housing, so made integrally or in one piece with it.
  • the housing therefore has a double function, on the one hand the housing of the cable bridges and on the other hand that of the support point of the connec tion ladder.
  • Figure 1 is a partial view of an electrical machine according to the invention with a connecting conductor of a first embodiment
  • Figure 2 is a view corresponding to Figure 1 with a connecting conductor of a second embodiment
  • FIG. 3 shows a further partial view with a connecting conductor of a third embodiment

  • FIG. 5 shows a detailed view of the area of the contact elements of the current connection without connected connecting conductors
  • FIG. 6 shows the arrangement from FIG. 5 with connected connecting conductors.
  • FIG. 1 shows, in the form of a partial view, a basic illustration of an electrical machine 1 according to the invention with a stator 2 with a winding 3 comprising a plurality of conductors 4, which are assigned to three separate phases in the example shown. More or fewer phases can also be provided.
  • Each conductor 4 is designed as a quasi U-shaped bracket, a plurality of such U-shaped Lei ter, often also called hairpins, are plugged together to form the winding 3, which can also be referred to as a winding basket.
  • the plurality of conductors 4 different radial planes R, as shown in FIG.
  • the conductors 4 extend, depending on the winding scheme, from one radial plane to another radial plane, for example an adjacent radial plane, in the area in which they are connected to the conductor ends of corresponding adjacent conductors continuing the phase conductor.
  • the conductors 4 are guided or bent and laid in such a way that corresponding recesses arise which extend radially so that corresponding stator teeth 5 engage in these recesses or the corresponding conductors 4 are wound between the corresponding grooves of the stator teeth 5.
  • the basic structure of such a stator or such an electrical machine and such a winding 3 wound from separate brackets is basically known.
  • the ends 6 of the conductors 4 project axially, as long as the ends 6 are positioned on the inner circumference and / or the outer circumference of the annular winding 3, i.e. they protrude axially from the winding 3.
  • These ends 6 are associated with individual conductors 4, which in turn are assigned un different phases, which is why the conductor ends 6 are to be interconnected according to the routing scheme of the conductor 4.
  • a formwork ring 7 is used, which is placed axially on the end face of the winding 3 and is arranged between the conductor ends 6 or engages between them.
  • the interconnection ring 7 comprises a number of corresponding line bridges, not shown in detail, as well as on connection sections that protrude to the side from the housing 8 and after inserting the circuit ring 7 between the conductor ends 6 are positioned precisely next to the corresponding conductor end 6 with which they are to be connected are.

  • the connecting conductor 12 has a laterally or circumferentially widened contact section 13 which, coming from the radially outer side, lies against the two conductor ends 6 to which it is to be welded. So it contacts two conductor ends 6 simultaneously.
