- a slip ring module is fitted onto the shaft end section, the slip ring of which is electrically connected to a connecting element running through the shaft end section.
- a bearing device is arranged on an outer surface of the shaft end section.
- the invention also relates to a method for producing the externally excited electrical machine according to the invention.
- a further subject of the invention is a motor vehicle with the externally excited electrical machine according to the invention.
- Separately excited electrical machines are generally known.
- the known separately excited electrical machines generally have a slip ring module on a shaft end section, which is plugged onto an outside or onto an outer surface of the shaft end section.
- a slip ring module On accommodate connecting elements of the slip ring module, grooves running in the axial direction of the rotor are formed in the outer surface.
- a bearing device sits on the shaft end section. Due to the grooves in the outer surface in the area of the bearing device, extensive sealing measures are required between the bearing device and the outer surface in order to prevent a cooling medium for cooling a rotor winding from reaching the slip rings of the slip ring module. These sealing measures can increase the cost of the electrical machine.
- the invention relates to an externally excited electric machine for a traction drive of an at least partially electrically driven motor vehicle, having a rotor shaft of a rotor, to which a shaft end section is adjacent and/or formed, wherein the shaft end section has a first opening and a second opening arranged at a distance from the first opening in an axial direction of the rotor, a potting body arranged in the shaft end section, in which an electrically conductive connecting element is embedded at least in sections, wherein the connecting element has a distal first end and a distal second end, and the distal second end can be guided or is guided through the second opening, a slip ring module arranged on a distal end section of the shaft end section with a slip ring and a connecting section arranged on the slip ring, which is electrically conductively connected to the distal first end of the connecting element, and a bearing device which sits on an outer circumferential surface of the shaft end section and via which the rotor can be mounted in
- an externally excited electric machine for a traction drive of an at least partially electrically driven motor vehicle.
- the externally excited electric machine has a rotor which comprises a rotor shaft.
- a shaft end section is arranged and/or formed adjacent to the rotor shaft.
- the shaft end section comprises a first opening and a second opening arranged at a distance from the first opening in an axial direction of the rotor.
- the first opening is preferably aligned coaxially to a longitudinal axis of the rotor and/or the rotor shaft.
- the first opening is particularly preferably designed as an edge-closed opening.
- the second opening is formed in a wall of the shaft end section; if the shaft end section is considered separately, the second opening on a side facing away from the first opening is preferably designed as a recess and/or slot and only achieves the formation of an edge-closed opening in combination and/or connection with the rotor shaft.
- a potting body is arranged in the shaft end section.
- An electrically conductive connecting element is at least partially arranged in the potting body. embedded.
- the connecting element has a distal first end and a distal second end. The distal second end can be guided or preferably guided through the second opening. A winding wire of a rotor winding of the rotor can thus be easily connected in an electrically conductive manner to the second end of the connecting element.
- a slip ring module is arranged on a distal end section of the shaft end section, which has a slip ring and a connecting section arranged on the slip ring.
- the connecting section is electrically conductively connected to the distal first end of the connecting element.
- a bearing device is provided, which sits on an outer surface of the shaft end section, preferably between the slip ring module and the second opening.
- the connecting element is guided through the shaft end section and creates an electrically conductive connection between the slip ring and the distal second end of the connecting element, which can be connected to the rotor winding, no grooves or recesses are required on the outer surface of the shaft end section in the area of the bearing device, so that the media tightness in this area can be increased in a simple and inexpensive manner.
- This can prevent a cooling medium for cooling a laminated core arranged on the rotor shaft from reaching the slip ring module in the area of the bearing device.
- a shaft sealing ring is arranged adjacent to the bearing device. It is therefore conceivable that the shaft sealing ring is arranged on a side of the bearing device facing the slip ring module and/or on a side of the bearing device facing away from the slip ring module. If the bearing device is designed to be self-lubricating, in other words, has a lubricant, in particular a grease, it is preferably provided that the shaft sealing ring is arranged on a side facing away from the slip ring module. This can prevent fluids, in particular a cooling medium for cooling a laminated core arranged on the rotor shaft, from penetrating the bearing device and reaching the slip ring module via the bearing device.
- the shaft sealing ring is arranged on a side facing the slip ring module.
- This arrangement is preferably provided if the bearing device is to be lubricated via the coolant for cooling the laminated core arranged on the rotor shaft.
- An advantageous development of the invention is that the outer surface is designed to be uninterrupted in an area in which the shaft seal sits on the shaft end section and/or seals against it. In other words, in the area in which the shaft seal sits on the outer surface, no grooves or channels are formed that extend in the axial direction of the rotor over a width of the shaft seal - based on the axial direction of the rotor or the shaft end section. The media tightness in the area of the shaft seal and thus also of the bearing device can thus be increased in a simple and inexpensive manner.
- the diameter of the shaft end section in the area of the bearing device and the shaft seal can have a reduced outer diameter. Due to the reduced outer diameter, the circumferential speed in the area of the shaft seal is reduced when the rotor rotates about its longitudinal axis, so that wear on the shaft seal can be reduced and the longevity of the shaft seal can be increased.
- the casting body is fixed in the shaft end section in the longitudinal direction of the rotor in a material-locking and/or form-fitting manner.
- the form-fitting fixation provides that the casting body is designed in such a way that it is held in the shaft end section in the longitudinal direction of the rotor by an internal geometry of the shaft end section on the one hand and the rotor shaft on the other.
- the potting body has a section in which a maximum outer diameter or outer cross section is larger than a smallest inner diameter of the shaft end section. In this way, a positional fixation of the potting body in the direction of the slip ring module can be made possible.
- the potting body is preferably made of an electrically insulating material.
- the potting body can particularly preferably be made of a plastic material or comprise a plastic. Such a potting body can be produced inexpensively.
- a Sealing element is arranged between an inner surface of the shaft end section and the casting body.
- the sealing element is preferably designed as a ring seal, in particular as an O-ring.
- the sealing element is particularly preferably made of a permanently elastic material. The sealing element can be used to prevent a fluid for cooling a laminated core arranged on the rotor shaft from passing through the second opening and an annular gap between the casting body and the inner surface of the shaft end section in the direction of the slip ring module.
- the distal first end is not guided through the first opening, but is designed to be recessed towards the first opening.
- the connecting section of the slip ring module protrudes through the first opening into the shaft end section in order to be connected in an electrically conductive manner to the distal first end of the connecting element. This can be advantageous for the axial installation space of the rotor or the separately excited electrical machine.
- a preferred development of the invention provides that the distal first end is guided through the first opening. In other words, the distal first end projects beyond the first opening. It is therefore not necessary for the connecting section of the slip ring module to project into the first opening in the shaft end section in order to be connected in an electrically conductive manner to the distal first end of the connecting element. In this way, the electrically conductive connection between the connecting section of the slip ring and the distal first end of the connecting element is not, or not significantly, hindered by the shaft end section, so that the electrically conductive connection can be implemented in a simple and inexpensive manner.
- the connecting section has a receiving opening for receiving the distal first end of the connecting element.
- the distal first end is preferably designed to be straight and runs in the axial and/or longitudinal direction of the rotor.
- the receiving opening of the connecting section is designed as either an edge-closed opening and/or a loop into which the straight distal first end of the connecting element engages when the slip ring module is plugged onto the shaft end section.
- the connecting section and the distal first end of the connecting element can thus be brought together in a simple and inexpensive manner in order to be connected to one another in an electrically conductive manner.
- the receiving opening can be formed in one piece in the connecting element.
- a pole shoe having the receiving opening is placed on the connecting section and the distal first end engages in the receiving opening of the pole shoe.
- the connecting section and the distal first end of the connecting element run parallel to one another at least in sections in the region of the electrically conductive connection, and the regions of the connecting element and the connecting section that run parallel to one another are preferably connected to one another in a materially bonded manner.
- the regions that run parallel to one another preferably run in a longitudinal direction of the shaft end section.
- the electrically conductive connection between the connecting section and the distal first end of the connecting element is a material connection, a force-fitting connection and/or a positive connection.
- the material connection is preferably a welded connection or an electrically conductive adhesive connection.
- the positive and/or force-fitting connection can be a press-fit connection.
- the slip ring module has a slip ring carrier, wherein the slip ring and the connecting section are arranged at least partially and/or in sections in the slip ring carrier.
- the slip ring module can be prepared in a simple manner in order to then be plugged onto the shaft end section of the rotor shaft. The production times of the separately excited electrical machine and consequently also the production costs can thus be reduced, since only the slip ring module as such is plugged onto the shaft end section and electrically connected to the connecting element.
- the slip ring module is plugged onto the shaft end section and the slip ring of the slip ring module is arranged at a distance in the radial direction from the outer surface of the shaft end section.
- the installation space of the separately excited electrical machine can thus be reduced in the axial direction.
- the invention relates to a method for producing the separately excited electrical machine according to the invention, comprising the steps:
- a method for producing the rotor according to the invention comprises at least the steps of providing a shaft end section.
- a casting body in which the connecting element is arranged is arranged in the shaft end section.
- the connecting element is guided within the shaft end section.
- the shaft end section is connected to the rotor shaft.
- the rotor shaft can be designed as a hollow shaft, but not limited to this. It is also conceivable that the rotor shaft has a solid cross-section.
- the rotor shaft is mounted in a housing via a bearing device.
- the bearing can be designed as a rolling bearing.
- the housing can be a housing wall or a bearing plate of the housing of the separately excited electrical machine. It is also provided that the slip ring module is arranged, in particular plugged, onto a distal end section of the shaft end section. The plugging preferably takes place in the axial direction of the rotor or the rotor shaft. Depending on the outer diameter of the slip ring module, it can be provided that the slip ring module is arranged on the distal end section of the shaft end section after the arrangement and/or storage of the rotor via the bearing device in the housing.
- the slip ring module is plugged onto the distal end section of the shaft end section and then the entire rotor, together with the slip ring module plugged onto the shaft end section, is stored in the housing via the bearing device.
- a method is provided with which a rotor can be arranged within a housing in a simple and inexpensive manner and increased media tightness can be achieved in the area of the housing or the bearing seat.
- a shaft sealing ring is arranged adjacent to and/or at a distance from the bearing device, which seals against the housing on the one hand and the shaft end section on the other hand.
- a preferred development of the invention provides that, in order to arrange the casting body having the connecting element in the shaft end section, a separate casting body having the connecting element is produced outside the hollow shaft and is arranged captively in the shaft end section.
- the casting body can be easily inserted into the shaft end section, preferably in the case of a built-up rotor or built-up rotor shaft, and can preferably be arranged in the shaft end section via a material-locking connection and/or positive-locking connection.
- the casting body is introduced into the shaft end section with the distal first end of the connecting element in front in a straight-line movement over a side facing away from the first opening of the shaft end section.
- the second opening if the shaft end section is considered as such, is designed as a recess and/or slot in a wall of the shaft end section.
- connection is preferably a material-bonded connection.
- the material-bonded connection is preferably a welded connection.
- the potting body is preferably designed in such a way that it cannot be guided entirely through the shaft end section beyond the first opening.
- the potting body has, at least in sections, an external cross-section that is larger than a smallest internal cross-section.
- the potting body has an external geometry that only allows the potting body to be introduced into the shaft end section via a side that faces away from the first opening.
- the potting body can thus be securely fixed in position in the axial direction within the rotor, at least in the direction of the slip ring module.
- the cast body is preferably fixed and/or positioned in the axial direction by the rotor shaft. It is conceivable that the rotor shaft is designed as a solid body.
- the rotor shaft itself then serves as a stop for the cast body. It is also conceivable, however, that the rotor shaft is designed as a hollow shaft. In this context, it is then provided that an external cross section and/or external diameter of the cast body that borders the rotor shaft is larger than an internal diameter of the hollow shaft that is aligned and/or designed adjacent to the cast body.
- the connecting element in order to arrange the casting body containing the connecting element in the shaft end section, the connecting element is first arranged in the shaft end section, then the casting body is introduced into the shaft end section and hardens therein. In other words, the casting body is formed "in-place". To do this, the connecting element is inserted into the shaft end section beforehand and then cast within the shaft end section. This allows a media-tight connection of the casting body to an inner side of the shaft end section in order to prevent fluid transport through the shaft end section.
- the invention relates to a motor vehicle with the separately excited electrical machine according to the invention.
- the motor vehicle is preferably an at least partially, preferably completely, electrically powered motor vehicle.
- the separately excited electric machine is preferably an integral component of a traction drive of the motor vehicle.

- the externally excited electrical machine FEM is set up and/or designed for a traction drive TA of an at least partially electrically driven motor vehicle KFZ.
- the separately excited electrical machine FEM has a rotor RO which encloses the rotor shaft RW.
- a laminated core BP with at least one salient pole (not shown) is arranged in a rotationally fixed manner on an outer circumferential surface AUF the rotor shaft RW.
- a rotor winding RW is usually wound on the salient pole.

- the shaft end section WEA comprises a first opening EO and a second opening ZO arranged at a distance from the first opening EO in an axial direction of the rotor RO.
- a casting body VK is arranged in the shaft end section WEA.
- An electrically conductive connecting element VE is embedded in the casting body VK at least in sections.
- the connecting element VE has a distal first end DEE and a distal second end DZE. In the present exemplary embodiment, the distal second end DZE is guided through the second opening ZO of the shaft end section WEA.
- a winding wire of the rotor winding RW can thus be electrically conductively connected to the distal second end DZE.
- the slip ring module SRM is arranged on a distal end section DE of the shaft end section WEA, which has a slip ring SR and a connecting section VA arranged on the slip ring SR.
- the connecting section VA is electrically conductively connected to the distal first end DEE of the connecting element VE.
- a bearing device LE is provided, which sits on an outer surface AM of the shaft end section WEA, preferably between the slip ring module SRM and the second opening ZO.
- the bearing device LE is arranged in a housing GE of the separately excited electrical machine FEM.

- the increased media tightness can prevent a liquid cooling medium for cooling the rotor RO, in particular the rotor winding RW and/or the laminated core BP, from reaching the slip ring module SRM.
- a shaft seal ring WDR is provided, which is arranged adjacent to the bearing device LE and seals between the housing GR and the outer surface AM.
- the shaft seal ring WDR is on a side of the bearing device LE facing away from the slip ring module SRM. This prevents a cooling medium for cooling the laminated core BP or the rotor winding from passing through the bearing device in the direction of the slip ring module SRM.
- the outer surface AM is designed to be uninterrupted in an area in which the shaft sealing ring sits on the shaft end section WEA. This can increase the media tightness in the area in which the bearing device LE sits on the shaft end section WEA.
- a diameter of the shaft end section WEA in the area of the bearing device LE and the shaft seal ring WDR can have a reduced outer diameter. Due to the reduced outer diameter, the circumferential speed in the area of the shaft seal ring WDR is reduced when the rotor RO rotates about its longitudinal axis, so that wear on the shaft seal ring WDR can be reduced and the service life of the shaft seal ring WDR can be increased.
