Definitions
- the invention relates to a stator for an electrical machine, with a winding comprising a plurality of conductors assigned to one or more phases, which are interconnected.
- Electrical machines comprising a rotor and a stator are used in different areas of application.
- the use of electrical 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.
- This area also includes the connection of the individual phases to an external power supply, often also called a high-voltage terminal, which is used to generate power. tion of the magnetic field is used, which is often very complicated to implement for reasons of space.
- a temperature sensor usually an NTC or PTC resistance element
- the thermal coupling of this temperature sensor with the winding turns out to be difficult, since the winding is wound very tightly or is fitted with pieces so that the temperature sensor cannot be inserted into the winding or inserted between adjacent wires. Therefore, mostly temperature sensors with an outer protective cover, in particular a plastic cover such as a shrink tube, are used, which protective cover completely surrounds the sensor head and a connection conductor at least over part of its length, the end section of the plastic cover on the sensor head being closed.
- the temperature sensor usually a two-pole sensor, also contains a cable that is connected to the power electronics in a suitable manner. The cable often has to bridge a long way from the sensor to the power electronics, since a suitable connection conductor to which the temperature sensor can be connected at all is spaced relatively far from the power electronics.
- the invention is based on the problem of specifying a stator that is improved in comparison and has the most compact structure possible.
- a stator of the type mentioned inven tion provided that the ends of at least part of the conductor on the inner circumference and / or on the outer circumference of the winding protrude axially or radially over the winding, with a connection ring axially or radially on the Winding is set to which the conductors are connected, and wherein at least one temperature sensor in thermal contact with the winding is arranged on the interconnection ring.
- the actual conductor connection and the arrangement of the temperature sensor are integrated into a common structural unit, namely in a connection ring that is axially frontal or radially inside or outside is placed on the winding, and which serves the conductor connection, but at the same time the temperature sensor is arranged, which is thermally coupled to the winding and is preferably axially, radially or tangentially on the winding.
- the interconnection ring itself makes it possible to separate the actual conductor interconnection, i.e. the interconnection of the individual conductors to form the corresponding phase-specific meander structures, and the interconnection for coupling with the power supply via a high-voltage terminal, with the interconnection virtually radially inward and the Connection to the power supply can be provided radially on the outside, for example if the ends of at least two conductors assigned to one phase protrude radially or axially outward and are connected to a power connection located radially outside the winding.
- the interconnection ring that is, a conductor ring that is placed separately on the winding and placed axially or radially on the turn, is used for the actual conductor connection.
- This interconnection ring engages in the area of axially or radially protruding conductor ends on the inner circumference and / or on the outer circumference of the winding, e.g. when placed axially between the area of the inner and outer circumference of the winding, conductor ends protruding axially over the windings.
- the conductor ends are the individual conductor sections, unless they are on other, z. B. are further connected to each other in the radial planes lying, assigned.
- the conductor ends are connected to the interconnection ring, usually welded to it, so that the corresponding phase-specific Lei terstructures are generated via the interconnection ring.
- the temperature sensor is also connected to this interconnection ring, that is to say integrated on the ring, so that a common structural unit results, which is used on the one hand for the conductor connection and on the other hand for temperature detection.
- the temperature sensor is also positioned at the same time and brought into thermal contact with the winding.
- the connection ring is placed axially, the temperature sensor also rests axially on the winding; with a radial arrangement of the connection ring, it would sit radially.
- the inventive, combined assembly of interconnection ring including temperature sensor allows the construction of a very compact stator while ver simplified assembly. Due to the quasi-nested, z. B. axial and radial arrangement of interconnection ring and power supply terminal results in a very compact, space-saving structure. In addition, assembly is also simplified, since the conductors or wires to be connected via the interconnection ring only have to be cut to length and brought into the appropriate position when the winding cage is plugged together in order to be connected to the corresponding connection terminals of the interconnection ring, which are of course positioned accordingly . Both the cutting to length and the assembling can take place in an automated assembly process, as can of course also be compensated for due to the simple connec tion of conductor ends and connection ring. This is not least due to the fact that the interconnection ring and the power supply or the HV terminal are two separate assemblies that are connected to the stator and then also to the finished electrical machine in different process steps.
- connection ring At the same time as the connection ring is put on, however, the temperature sensor is also installed and thermally coupled, which means that no additional, separate installation steps are required for sensor installation. Rather, If the connection ring is set and assembled automatically, the temperature sensor assembly is also automated, which simplifies the entire assembly process. In addition, due to the integration of the temperature sensor in the interconnection ring, a very compact design is possible, since no separate lines and the like are required for the electrical connection of the temperature sensor, since the line connection to the power electronics can also be routed through the interconnection ring.
- connection ring itself expediently has a housing in which a plurality of separate line bridges are arranged, the temperature sensor being arranged in or on the housing and protruding towards the winding.
- the integrated structural unit thus has a housing that closes it off from the outside, which makes it possible to completely prefabricate the structural unit and to assemble it as a compact housing component.
- several cable bridges which are stable metal sheets that are geometrically shaped so that they reach the conductor ends to be connected, are grouped to form the corresponding circuit ring and allow easy bridging of corresponding distances both in circumferential and in Radial direction. These cable bridges, like the individual conductors, are of course insulated from one another.
- the temperature sensor is arranged in or on the housing in such a way that it protrudes from or on the housing towards the winding.
- the housing thus offers a simple, standardized interface for positioning and mounting the temperature sensor, so that it is ensured that the temperature sensor is always positioned in a way that enables reliable thermal contact with the winding.
- the housing in which the bridges and on which the temperature sensor is arranged preferably has corresponding radial openings for the protruding connections of the individual conductor bridges that emerge here, and one or more, corresponding number of temperature sensors to be mounted, axial openings through which the temperature sensor or sensors, of which several can of course also be provided, protrude from the housing and protrude towards the winding, or through which the connecting lines of the temperature sensors arranged on the outside of the housing run.
- This configuration is with an axial placement of the Connection ring useful.
- connection ring If the connection ring is placed radially, the openings and the protruding conductor bridge sections can project axially, while the openings for the temperature sensors are aligned radially so that the temperature sensors rest radially on the outer circumference of the winding.
- the housing is preferably a plastic housing, which enables simple manufacture.
- the temperature sensor is spring-loaded against the winding via an elastic element.
- This elastic element and the resilience ensure that the tem perature sensor is pressed firmly against the winding, on the one hand, and is therefore brought into firm thermal contact.
- any tolerances between the interconnection ring or the housing and the winding surface can also be compensated for.
- the temperature sensor can also be arranged in a fixed position, ie not flexibly on the housing via an elastic cal element, if it is ensured that it comes into defined thermal contact with the contact surface of the winding.
- a plastic component in particular a silicone or elastomer component
- a spring element can also be provided.
- the elastic element can also have a metal element, in particular a copper core, which is thermally coupled to the temperature sensor so that the metal element is practically in contact with the winding and thermally with the temperature sensor, which is then virtually indirectly coupled to the winding , connected is. This enables the temperature to be sent more directly and better to the temperature sensor or the so-called "sensor bead".
- the temperature sensor and / or the metal element is, of course, both embedded in the plastic component, that is to say, for example, injected or poured into the silicone or elastomer component.
- This results in a compact temperature sensor component that has flexibility or spring properties provides so that the embedded temperature sensor, which is designed for example in the form of a sensor bead and for example protrudes slightly from the plastic material, can be spring-loaded accordingly.
- the metal element for example in the form of one or more suitable metal strips or the like, is also embedded, this joint embedding can bring it into extensive thermal contact with the adjacent winding, that is to say that a larger area Temperature sensor component results.
- the temperature sensor or the temperature sensor component can, as already described ben, rest axially, radially or tangentially on the winding. Ultimately, the alignment and thermal coupling of the sensor depends on how the interconnection ring is placed on the winding or attached to it.
- the temperature sensor itself is preferably a thermocouple, e.g. B. an NTC or a PTC sensor. While it is sufficient to provide only one temperature sensor on the interconnection ring, it is of course also conceivable to arrange several temperature sensors or temperature sensor component distributed on the interconnection ring.
- the invention also relates to an electrical machine to include a stator of the type described above.
- FIG. 1 shows a basic illustration in the form of a partial view of a stator according to the invention
- Figure 2 is a partial view of the interconnection ring
- FIG. 3 shows a basic representation of various line bridges of the connection ring from FIG. 2 together with two temperature sensor components
- FIG. 4 shows an enlarged basic illustration in perspective view of a temperature sensor component
- Figure 5 is a perspective view of the actual temperature sensor
- FIG. 6 shows a partial view of the stator with the connecting ring attached and the temperature sensor component in thermal contact.
- FIG. 1 shows, in the form of a partial view, a basic illustration of a stator 1 according to the invention of an electrical machine, with a winding 2 comprising a plurality of conductors 3, which are assigned to three separate phases in the example shown. More or fewer phases can also be provided.
- Each conductor 3 is designed as a U-shaped bracket, with a large number of such U-shaped Lei ter, often also called hairpins, are plugged together to form the winding 2, which can also be referred to as a winding basket.
- the plurality of conductors 3 define different radial planes R, as shown in FIG.
- the conductors 3 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 are guided or bent and laid in such a way that corresponding recesses 4 result, which extend radially so that corresponding
- Stator teeth 5 engage in these recesses 4 or the corresponding conductors are wound between the corresponding grooves of the stator teeth 5.
- the basic structure of such a stator or a winding 2 wound from the separate brackets described is basically known.
- the ends 6 of the conductors 3 protrude axially, as long as the ends 6 end or are positioned at the inner circumference and the outer circumference of the annular winding 2, that is, they protrude axially from the winding 2.
- These ends are associated with individual conductors, which in turn are assigned to different phases, which is why the conductor ends are to be connected according to the routing diagram of the conductor 3.
- a connection ring 7 is used for this, which is placed axially on the end face of the winding 2 and is arranged between the conductor ends 6 or engages between them.
- the interconnection ring 7 comprises, as will be discussed below, a plurality of corresponding power bridges and connection sections 8, which protrude to the side from the housing 9 of the interconnection ring 7 and after inserting the interconnection ring 7 between the conductor ends 6 in the exact position next to the corresponding one Conductor end 6 are positioned with which they are to be connected.
- the connection is made e.g. B. by simple welding, so that all conductors 3 are correctly and phase-specifically connected to each other when they are connected. Other connection methods are also conceivable.
- a power supply 14 is provided, which is arranged radially next to the winding 2 in the area of its axial end.
- This power supply 14, also called HV terminal, comprises a housing 10 in which corresponding busbars 11 are arranged, which ra gene with their connection terminals 12 from the housing.
- connection terminals 12 are also provided in the example shown.
- connection terminal 12 is to be connected to one phase of the winding 2. This is implemented in a simple manner in that two conductor ends 6a per phase are guided radially outward or are bent, as FIG. 1 clearly shows.
- the at the arranged on the outer circumference of the winding 2 conductor ends 6a are relatively short and can be bent directly outwards, while the two conductor ends 6a arranged on the réelleum are longer and the interconnection ring 7 overgrei fen. They run above the connection terminals 12, so that a simple welded connection for contacting is possible there as well.
- the connection to the power supply 14 is only made when the conductors 3 are interconnected via the interconnection ring 7 miteinan.
- FIG. 2 shows a partial view of the interconnection ring 7 from FIG. 1.
- the housing 9 is shown, which is accordingly in several parts and also made a radial encapsulation light. It is preferably made of plastic. It can be seen that the corresponding connection sections 8, which are assigned under different phases, protrude from the housing 9 through corresponding openings 15. As already described, the individual connection sections are assigned to different phases, i.e. they connect different conductor ends. In the example shown, two temperature sensor components 16, which are used to detect the winding temperature, are also arranged or integrated on the connection ring 7. The temperature sensor components 16 are arranged in or on the housing and are received in corresponding openings 15 of the housing 9, through which they protrude axially in the example shown, or through which the connection lines are guided when the temperature sensor components 16 are arranged on the outside.
- the temperature sensor components 16 (instead of the two temperature sensor components shown, only one temperature sensor component 16 or more than two temperature sensor components 16 can be provided) are arranged on the housing 9 together with the line bridges 13, resulting in a combined structural unit which, on the one hand, is the Conductor interconnection, on the other hand, serves to record the temperature.
- the Conductor interconnection serves to record the temperature.
- FIG. 3 shows various separate line bridges 13 in the form of a schematic diagram, with six line bridges 13 being shown in the example shown, which are arranged axially and radially offset from one another.
- the corresponding connection sections 8 are formed, which in their entirety form a corresponding star distributor.
- Corresponding circumferentially offset conductor ends can be connected accordingly on the inner and outer circumference via the line bridges 13 extending in the circumferential direction, so that the corresponding meander structures of the individual phase conductors are formed or the like.
- the two temperature sensor components 16 which are arranged at suitable positions where there is appropriate space for integration between the line bridges 13.
- the arrangement of the line bridges 13 shown corresponds to that as received in the housing 9 according to FIG.
- FIG 4 shows in the form of a perspective schematic representation of a temperature sensor component 16.
- This includes a temperature sensor 17 shown in Figure 5 with the actual NTC or PTC sensor 18, often also called sensor bead, and two signal lines 19, via which the temperature sensor component 16 with the to the connection ring 7 external power electronics is connected.
- the corresponding signal lines 19 are led through the connection ring 7 or the housing 9 to the corresponding connections of the power electronics.
- the temperature sensor 17 is embedded in an elastic element 20, preferably an elastic plastic component made of silicone or an elastomer, as FIG. 4 shows.
- a metal element 21 or a metal core which is in thermal contact with the sensor element 17 and which metal element 21 can be used to increase the contact area to the actual winding 2, can also be embedded in this elastic element 20.
- the metal element would be exposed on the flat underside 22, so that it would come into thermal contact with the winding 2 immediately when the connection ring 7 is mounted.
- such a metal element 21 is optional.
- the elastic element 20 represents a pretensioning means by means of which the temperature sensor 17 is spring-loaded against the winding surface, that is to say is pressed against it, the elastic element 20 being able to be counter-supported on the housing 9. This ensures that even if the distance between the lower side of the housing and the upper side of the winding varies slightly, the temperature sensor 17 is always in thermal contact with the winding surface.
- the elastic element 20 therefore represents a compensation element.
- FIG. 6 shows a partial view of the stator 1 according to the invention and the winding 2 as well as the connection ring 7.
- the temperature sensor component 16 is clearly arranged on the underside 23 of the housing 9 or supported there.
- the signal lines 19 are led through the opening 15 into the interior of the housing.
- the temperature sensor component 16 is pressed with its underside 22 against the winding 2, so that the temperature sensor 17 is in thermal contact with the winding 2 and can therefore detect its temperature.
