DE102018203939A1 discloses a stator for an electric motor. DE102019112389B4 discloses a stator for an electric motor. CH343509A also discloses a stator winding. Summary of the Invention
[0003] The object of the present invention is to realize an arrangement structure of at least one winding on a lamination assembly for an electric motor, a method for manufacturing a stator or rotor for an electric motor, a stator for an electric motor, a rotor for an electric motor, and an electric motor for a motor vehicle, such that particularly advantageous temperature regulation of the electric motor can be achieved.
[0004] The task, according to the invention, is solved by an arrangement having the features of claim 1, a method having the features of claim 7, a stator having the features of claim 13, a rotor having the features of claim 14, and an electric motor having the features of claim 15. Advantageous aspects of the invention are the subject of the dependent claims.
[0005] A first aspect of the invention relates to an arrangement of at least one winding on a lamination assembly for an electric motor, particularly an electric motor for motor vehicles. This means that the motor, in its fully manufactured state, has the arrangement and therefore the winding and the lamination assembly, the winding and the lamination assembly being constructed separately. In particular, the winding is made of a metallic material, such as copper. The lamination assembly is made of a metallic material. In particular, it is conceivable that the winding is made of a first metallic material and the lamination assembly is made of a second metallic material different from the first metallic material. Preferably, the motor is a high-voltage component, the voltage of which, in particular the operating voltage or rated voltage, is preferably greater than 50 volts, especially greater than 60 volts, and very preferably several hundred volts. In the arrangement, the lamination assembly has at least one slot. The at least one slot is also referred to as the first slot. Unless otherwise stated, "slot" or "at least one slot" in the foregoing and hereinafter refers to the first slot. Multiple length regions of the winding are received and thus provided in the slot. In the arrangement, the winding is held on and thus supported by the lamination assembly. For example, the stack has a plurality of slots, namely the first slot mentioned above and at least one or more other slots, the slots of the stack being arranged successively in the circumferential direction of the stack and, in particular, spaced apart from each other.
[0006] The motor, in its fully manufactured state, has a stator or rotor, the rotor being driven by the stator and thus able to rotate relative to the stator about the motor's rotational axis. The circumferential direction of the lamination assembly extends about the motor's rotational axis. The axial direction of the lamination assembly coincides with the motor's rotational axis; the lamination assembly can be selectively used as a stator lamination assembly or a rotor lamination assembly. The radial direction of the lamination assembly extends perpendicular to the axial direction of the lamination assembly and thus perpendicular to the motor's rotational axis; the lamination assembly, for example, consists of multiple lamination segments, separately constructed and also referred to as single laminations. For example, the motor, in its fully manufactured state, can provide driving torque via the rotor for electric motor vehicles, especially for purely electric motor vehicles. The winding is also referred to as the first winding. Unless otherwise stated, the term "winding" in the foregoing and hereinafter refers to the first winding. Additional length regions of the first winding and / or the length regions of the second winding are provided and thus received in corresponding additional slots.
[0007] To enable advantageous temperature control, i.e., cooling and / or heating, of the laminations and / or windings, and thus the motor, plastic is disposed in the slot between at least one of the length regions disposed in the slot and the laminations. This specifically means that a plastic element, preferably solid, is disposed in the slot between the at least one length region and the laminations. A temperature-regulating channel is defined by the plastic, i.e., by the element and by the at least one length region, the channel being circulated by a temperature-regulating medium, preferably a liquid, for temperature control, i.e., cooling and / or heating of the laminations and / or the at least one length region. Preferably, the temperature-regulating medium is an integral part of the arrangement. In principle, a gas is considered as the temperature-regulating medium. However, a liquid is very effective. For example, oil is a temperature-regulating medium. Alternatively, water may be considered as the temperature-regulating medium. Heat can be exchanged between the temperature-regulating medium and the at least one length region and / or between the temperature-regulating medium and the lamination assembly along the path of the temperature-regulating medium through the temperature-regulating channel. Therefore, the at least one length region and / or the lamination assembly can be temperature-regulated, i.e., cooled and / or heated. For example, to cool the at least one length region and / or the lamination assembly, the temperature-regulating medium has a lower temperature than the at least one length region and / or the lamination assembly along its path through the temperature-regulating channel, so that heat can be transferred from the at least one length region or the lamination assembly to the temperature-regulating medium. For example, to heat the at least one length region and / or the lamination assembly, the temperature-regulating medium has a higher temperature than the at least one length region and / or the lamination assembly along its path through the temperature-regulating channel, so that heat can be transferred from the temperature-regulating medium to the at least one length region or the lamination assembly. Therefore, it is specifically stipulated that, in methods for operating a motor, the temperature-regulating medium flows through the temperature-regulating channel, particularly in the flow direction.
[0008] Preferably, the temperature regulating channel extends perpendicularly to a plane, which extends perpendicularly to the axial direction of the lamination assembly. The axial direction of the lamination assembly coincides with the rotation axis of the motor. In particular, it is conceivable that the temperature regulating channel extends in the axial direction of the lamination assembly and therefore in the axial direction of the motor, i.e., parallel to the axial direction of the lamination assembly, such that, for example, the temperature regulating channel extends perpendicularly to the plane.
[0009] This invention enables particularly advantageous temperature regulation of the motor, allowing for exceptionally high operating capacity. Specifically, it avoids both excessively high and excessively low temperatures during motor operation. Background of the invention: In particular, the long regions of the windings, which are high-heat-load conductors constituting the conduction of electrical energy or current, can now be particularly effectively and efficiently temperature-regulated, especially cooled, by this invention. The at least one long region and the plastic are used to define a temperature-regulating channel, specifically directly defining the temperature-regulating channel. This temperature-regulating channel is therefore a flow space located very close to the at least one long region and thus close to the conductor, through which the temperature-regulating medium can flow, or rather, through, during the aforementioned motor operation.
[0010] The corresponding length region includes, for example, a conductor made of a metallic material, particularly a first metallic material, and, for example, a cladding, the winding being made of the first metallic material, the cladding being made of, for example, a material different from the metallic material, the winding, and therefore the conductor, being made of the metallic material. The conductor, in particular, is completely surrounded or enclosed by the cladding along its circumference, and thus is wrapped by or enclosed by the cladding. In particular, it is conceivable that the temperature-regulating channel is defined directly by the cladding on one hand and directly by the plastic on the other, such that the temperature-regulating medium, in its path through the temperature-regulating channel, directly contacts the cladding or the at least one length region on one hand and directly contacts the plastic on the other. This allows for a particularly advantageous temperature regulation. Because the at least one length region on one hand and the plastic on the other hand are used to define the temperature-regulating channel, additional structural elements for forming the temperature-regulating channel can be avoided, allowing effective and efficient temperature regulation to be achieved in a particularly simple manner, advantageous in terms of weight, cost, and structural space.
[0011] In order to achieve particularly advantageous temperature control in a particularly advantageous manner, in one embodiment of the invention, it is specified that plastic is injected into the tank and thus into the stack of sheets, especially directly into the stack of sheets.
[0012] Another embodiment is characterized by an object constructed separately from the laminations and from the length region disposed in the slot by means of plastic, said object being particularly solid and, for example, the element mentioned above. Thus, the laminations or the slot can be provided with plastic in a particularly simple and therefore time- and cost-effective manner, enabling the advantageous temperature control of the motor to be formed in a particularly advantageous way.
[0013] In another embodiment of the invention, the length regions are arranged successively in the groove along an arrangement direction, particularly a linear arrangement direction. The arrangement direction extends, for example, in the plane mentioned above. In particular, it is conceivable that the arrangement direction extends in the radial direction of the stack and thus perpendicular to the axial direction of the stack.
[0014] It has proven particularly advantageous that the temperature regulating channel is positioned along the arrangement direction between the at least one length region, also known as the first length region, and a second length region among the length regions disposed in the slot, the second length region directly following the at least one length region along the arrangement direction. The feature "the second length region follows the first length region non-indirectly, i.e., directly, along the arrangement direction" can be understood as the first and second length regions being adjacent to each other along the arrangement direction, such that, when viewed along the arrangement direction, there are no other length regions of the winding or other windings located between the first and second length regions. It is specified here that the temperature regulating channel is defined by plastic, by the first length region, and by the second length region, and in particular, directly, respectively. Therefore, particularly advantageous temperature regulation can be guaranteed. The description of the first length region, i.e., the at least one length region, in the foregoing and hereinafter can also be readily applied to the second length region, and vice versa.
[0015] Another embodiment is characterized in that the plastic is electrically insulating. Therefore, the plastic, or the object, is a non-conductor, also known as an insulator, with a conductivity of less than 10. -8 S*cm -1 Therefore, plastic fulfills a dual function. On the one hand, plastic is used to define, and especially directly define, the temperature control channel. On the other hand, plastic is used as slot insulation to achieve advantageous electrical insulation. Thus, particularly advantageous temperature control of the motor can be achieved in a manner particularly favorable to weight, structural space, and cost. In particular, by means of plastic that acts as slot insulation or is used as slot insulation, electrical insulation between the long region disposed in the slot and the lamination assembly can be achieved, thus avoiding the need for additional separate components to achieve such slot insulation.
[0016] A second aspect of the invention relates to a method for manufacturing a stator or rotor for an electric motor. Hereinafter, stator and rotor are generally referred to as motor components; therefore, when referring to motor components hereinafter, unless otherwise stated, motor components can be understood as rotor and stator.
[0017] In the method according to the invention, a lamination assembly of motor components is provided, the lamination assembly having at least one slot. In the method, multiple length regions of a winding are provided in the slot, particularly the winding is separately formed from the lamination assembly and is fixed to the lamination assembly.
[0018] To enable particularly advantageous temperature control of the motor components and therefore the motor, a second aspect of the invention specifies that plastic is disposed in the groove, such that the plastic is positioned between at least one of the length regions disposed in the groove and the lamination group. This can be understood in particular as the plastic being positioned between at least one of the length regions disposed in the groove and the lamination group while the motor components are fully manufactured. In principle, it is conceivable to place the at least one length region in the groove before the plastic is placed there; then place the plastic in the groove so that it is positioned between the at least one length region and the lamination group. Alternatively, and particularly advantageously, it is conceivable to place the plastic in the groove before the at least one length region, especially each length region, is placed there; then place the at least one length region, especially each length region, in the groove, so that the plastic is positioned between the at least one length region and the lamination group. Therefore, the steps of the method need not necessarily be performed in the listed order.
[0019] In the method according to the second aspect of the invention, a temperature-regulating channel is further defined and thus constituted by the plastic and the at least one length region, the temperature-regulating channel being disposed between the plastic and the at least one length region, the temperature-regulating channel being traversable by a temperature-regulating medium for temperature regulation, i.e., cooling and / or heating, of the stacked assembly and / or the at least one length region. The advantages and benefits of the first aspect of the invention can be considered as advantages and benefits of the second aspect of the invention, and vice versa.
[0020] To enable particularly simple, time- and cost-effective temperature control of the motor components and thus the motor itself, in one embodiment of the second aspect of the invention, the plastic is injected into a tank. Thus, for example, an injection molding method, particularly injection molding, is implemented, in which the plastic, especially in a liquid state, is injected into the tank, and thus injected towards the stack, particularly directly towards the stack. The plastic then undergoes age hardening, for example, to form a solid object composed of plastic. For example, each length region, and thus at least one length region, is then positioned in the tank so that the plastic, or the object, is positioned between the at least one length region and the stack.
[0021] To manufacture motor components in a particularly advantageous, and especially time- and cost-effective manner, and thus to achieve particularly advantageous temperature control of the motor components in a particularly time- and cost-effective way, in another aspect of the second aspect of the invention, it is specified that in the method, a plastic body is provided, which is constructed separately from the winding and from the lamination assembly, and is manufactured independently of the lamination assembly and independently of the winding, and is made of plastic. The plastic body, and therefore the plastic, especially in its solid state, moves relative to the lamination assembly and thus moves into the slot, so that the plastic body, and therefore the plastic, especially in its solid state, is disposed in the slot. Specifically, it is specified that the plastic body, and therefore the plastic, is disposed in the slot while at least one length region, especially each length region, is still disposed outside the slot, especially completely disposed outside the slot, i.e., not yet disposed in the slot; then, at least one length region of the winding, especially each length region, is disposed in the slot, especially for thus disposing the plastic between the at least one length region and the lamination assembly. Therefore, it is possible to manufacture plastic bodies and laminates in parallel over time, enabling particularly cost-effective manufacturing of motor components.
[0022] In another particularly advantageous embodiment of the invention, after the plastic body (such as the object mentioned above) is placed in the tank, the plastic body is deformed, especially while it is in a solid state. Therefore, the plastic body can, for example, advantageously, and particularly over a large area, adhere to the stack, enabling the formation of a particularly advantageous temperature control in a particularly simple manner. In particular, advantageous heat exchange between the temperature-regulating medium flowing through the temperature-regulating channel and the stack can thus be ensured, for example, by means of the plastic body.
[0023] For example, the plastic body is deformed during its placement in the tank by being subjected to pressure, particularly direct pressure, thus deforming the plastic body. For this purpose, a fluid is introduced into the tank, so the plastic body placed in the tank is loaded, particularly directly, by the fluid, which generates pressure, i.e., the pressure is applied to the plastic body at least indirectly, particularly directly, and is, for example, in the form of a gas. Therefore, for example, an internal high-pressure forming method (IHU method), also known as internal high-pressure forming or IHU, is implemented, thereby deforming the plastic body placed in the tank. In the IHU method, fluid is introduced into the tank, so the plastic body is loaded, at least indirectly, particularly directly, by the fluid, and thus deformed. Therefore, particularly advantageous temperature control can be achieved in a particularly advantageous manner. Especially after the IHU method, the at least one length region, particularly each length region, is placed in the tank.
[0024] To achieve particularly advantageous temperature control of the motor components, in another aspect of the invention, the plastic body is deformed such that a portion of the plastic body originally spaced apart from the wall regions of the lamination assembly is placed in support abutment, particularly direct support abutment, with these wall regions defining the groove, particularly directly defining the groove. Thus, the plastic body is particularly advantageously, particularly with a particularly large area, adhered to the wall regions, and therefore to the lamination assembly, ensuring particularly advantageous, effective, and efficient heat exchange between the temperature-regulating medium and the lamination assembly.
[0025] Another embodiment of the second aspect of the invention is characterized in that at least one cavity is created in the plastic body by deforming it, the cavity defining, in particular directly defining, a temperature-regulating channel. Specifically, the cavity is concave and therefore arched away from the at least one length region. Thus, the temperature-regulating channel can be manufactured simply and efficiently, enabling effective temperature regulation.
[0026] A third aspect of the invention relates to a stator for an electric motor, wherein the stator has an arrangement according to a first aspect of the invention. The advantages and benefits of the first and second aspects of the invention can be considered as advantages and benefits of the third aspect of the invention, and vice versa. Therefore, in the third aspect of the invention, the lamination group is the lamination group of the stator, and the winding is the winding of the stator, also referred to as the stator winding.
[0027] The fourth aspect of the invention relates to a rotor for an electric motor, wherein the rotor has an arrangement according to the first aspect of the invention. The advantages and benefits of the first, second, and third aspects of the invention can be considered as advantages and benefits of the fourth aspect of the invention, and vice versa. Therefore, in the fourth aspect of the invention, the lamination group is the lamination group of the rotor, and the winding is the winding of the rotor, also referred to as the rotor winding.
[0028] The fifth aspect of the invention relates to an electric motor for a motor vehicle, wherein the electric motor according to the fifth aspect of the invention has a stator according to the third aspect of the invention and / or a rotor according to the fourth aspect of the invention. The advantages and benefits of the first, second, third, and fourth aspects of the invention can be considered as advantages and benefits of the fifth aspect of the invention, and vice versa.

[0037] Figure 1 A motor component 1 for an electric motor, particularly for an electric motor for a motor vehicle, is shown in a schematic and sectional front view. Motor component 1 is either the rotor or the stator of the motor, such that the description of motor component 1 above and below applies not only to the rotor of the motor but also to the stator. Figure 1 This illustrates a first embodiment of the motor component 1. The motor, in its fully manufactured state, has a stator and a rotor, the rotor being driven by the stator and thus able to rotate relative to the stator about the motor's rotation axis. The motor can provide driving torque through its rotor, enabling electric drive, particularly pure electric drive, of a motor vehicle. The motor component 1 has an arrangement structure 2, wherein at least one winding 3 is arranged on a lamination group 4. Therefore, Figure 1 Arrangement 2 is partially shown in a schematic and sectional front view. It can be seen that the motor component 1 has a lamination group 4, a winding 3, and arrangement 2. The winding 3 is constructed separately from the lamination group 4. The lamination group 4 has a plurality of slots 5 that are sequentially arranged and spaced apart from each other in the circumferential direction of the lamination group 4. The axial direction of the lamination group 4 coincides with the rotation axis of the motor. The circumferential direction of the lamination group is described by double arrows 6 and extends around the rotation axis of the motor and therefore around the axial direction of the lamination group 4. The radial direction of the lamination group extends perpendicularly to the axial direction of the lamination group 4. The axial direction of the lamination group 4, and therefore the axial direction of the motor and the axial direction of the motor component 1, is described by double arrows 7. This axial direction coincides with... Figure 1The drawing plane extends vertically. The radial direction of the lamination group 4, and therefore the radial direction of the motor and the radial direction of the motor component 1, is described by double arrows 8. The corresponding slot 5 is defined on both sides by the lamination group 4, and in particular directly, in the circumferential direction of the motor component 1, and therefore in the circumferential direction of the lamination group 4. In the inward radial direction of the motor component 1 and the lamination group 4, the corresponding slot 5 is open when viewed alone. In the outward radial direction of the lamination group 4, the corresponding slot is defined by the lamination group 4, and in particular directly, when viewed alone. It can be seen that a corresponding closing element 9, also called a cover slide or configured as a cover slide, is provided in the corresponding slot. The cover closing element is configured separately from the winding 3 and separately from the lamination group 4. By means of the corresponding closing element 9, the corresponding slot 5 is closed, and in particular completely closed, in the inward radial direction of the lamination group 4.
[0038] Depend on Figure 1 As can be seen, multiple length regions L of the winding 3 are received and thus disposed in at least one of the slots 5. Each length region L has a corresponding conductive conductor 10 for conducting and transmitting electrical energy or current. The corresponding conductor 10 is made of a material, especially a metallic material, such as copper. For example, the conductors 10 of each length region L of the winding 3 received in the at least one slot 5 can be constructed as a single piece, i.e., constituted by a single object. Furthermore, each length region L has a corresponding cladding 11, and the corresponding conductor 10 of the corresponding length region L is either surrounded by or enclosed by the cladding 11 in the circumferential direction of the corresponding conductor 10—especially completely surrounding it—such that the corresponding cladding 11 directly contacts the corresponding associated conductor 10. For example, the corresponding cladding 11 is made of varnish, especially of electrically insulating varnish, such that, for example, the cladding 11 is non-conductive. Within the scope of this disclosure, non-conductive can be understood as having a conductivity of less than 10. -8 S*cm -1 The non-conductor. The material constituting the corresponding conductor 10 is also called the first material. For example, the laminate group 4 is composed of a second material that is different from the first material, such as a metallic material.
[0039] In order to achieve the particularly advantageous temperature control, i.e., heating and / or cooling, of the motor component 1 and thus the particularly advantageous temperature control, i.e., heating and / or cooling, of the motor having the motor component 1, a plastic K is received in the corresponding slot 5 between the length region L disposed in the corresponding slot 5 and the lamination group 4. (The last sentence appears to be incomplete and possibly refers to a different document.) Figure 1In the first embodiment, a corresponding object 12 made of plastic K is disposed in a corresponding groove 5 between a corresponding length region L disposed in the corresponding groove 5 and a stack of sheets 4. Currently, the objects 12 are disposed separately from each other. Because the corresponding objects 12 are made of plastic, the corresponding objects 12 are corresponding plastic bodies.
[0040] Temperature regulating channels 13 are defined, in particular, directly, by the plastic K and by at least one of the length regions L in the respective tanks 5. These channels are positioned between the plastic K and the at least one length region L and are circulated by a temperature regulating medium, preferably a liquid, for regulating the temperature of the stacked assembly 4 and / or the at least one length region L. Thus, the respective temperature regulating channels 13 are defined, on the one hand, by the plastic K, in particular, directly by the plastic, and on the other hand, by the respective coverings 11 of the respective length regions L, in particular, directly by the coverings, such that the temperature regulating medium directly contacts the plastic K and the respective coverings 11 along its path through the temperature regulating channels 13.
[0041] Especially good by Figure 1 As can be seen, the respective length regions L arranged in the respective slots 5 are arranged successively along the arrangement direction. The arrangement direction is described by double arrows 15, and in the first embodiment extends in the radial direction of the motor component 1 and therefore the lamination group 4. In the first embodiment, viewed along the arrangement direction, at least one or exactly one temperature regulating channel 13 or at least two or exactly two temperature regulating channels 13 are provided between every two length regions L that are not indirectly and therefore directly succeed each other and therefore adjacent to each other along the arrangement direction, thus enabling effective and efficient temperature regulation. Therefore, the respective temperature regulating channels 13 are defined on the one hand by the plastic K, especially directly by the plastic, and on the other hand by the adjacent length regions L, especially directly by the adjacent length regions, especially by their coverings 11. Thus, effective and efficient temperature regulation can be achieved. In the first embodiment, viewed along the arrangement direction and in pairs, at least one temperature regulating channel 13 is provided between any length regions L that are adjacent to each other along the arrangement direction.
[0042] Figure 2 The second embodiment of the motor component 1 is shown in a schematic and sectional front view, and thus the second embodiment of the arrangement structure 2 is also shown. In the second embodiment, viewed along the arrangement direction, at least one or exactly one temperature regulating channel 13 is provided only between every second adjacent length region L along the arrangement direction, and in particular at least two or exactly two temperature regulating channels 13.
[0043] Figure 3 The third embodiment of the motor component 1 is shown, and therefore the third embodiment of the arrangement structure 3 is shown. The corresponding length regions L of the winding 3, received in the corresponding slots 5, form a group of length regions, wherein, as explained above, each length region L is arranged successively along the arrangement direction (double arrow 15). Each group of length regions has a first side S1 and a second side S2, and the sides S1 and S2 of the corresponding group of length regions point away from each other in the circumferential direction of the motor component 1 and therefore in the circumferential direction of the lamination group 4, i.e., away from each other. In the first, second, and third embodiments, corresponding temperature regulating channels 13 are provided not only on the corresponding first side S1 but also on the corresponding second side S2, and the temperature regulating channels 13 provided on the corresponding sides S1 and S2 are arranged successively along the arrangement direction. The temperature regulating channels 13 provided on the corresponding side S1 form a first group of temperature regulating channels, and the temperature regulating channels provided on the corresponding side S2 form a second group of temperature regulating channels. In the first and second embodiments, the first group of temperature regulating channels and the second group of temperature regulating channels are arranged at the same height along the arrangement direction, i.e., they are not staggered.
[0044] In display Figure 3 In the third embodiment, the first temperature-regulating channel group is staggered from the second temperature-regulating channel group along the arrangement direction, such that when observed in pairs, only one temperature-regulating channel 13 is provided between each pair of length regions L that are directly adjacent to each other along the arrangement direction, i.e., exactly one temperature-regulating channel.
[0045] In the first, second, and third embodiments, the respective temperature-regulating channels 13 are defined, in particular, directly by a concave portion T of the plastic K that is thus arched away from the at least one length region L.
[0046] Figure 4 A schematic and sectional front view showing a partial view of the fourth embodiment of the motor component 1 and thus the fourth embodiment of the arrangement structure 2. In the fourth embodiment, the corresponding portion T of the plastic K extends at an angle.
[0047] Figure 5 The schematic perspective view shows the plastic body, indicated by 14 mentioned above, which is made of plastic K, i.e., manufactured using... Figure 5 The first embodiment for manufacturing motor component 1 and thus for manufacturing arrangement structure 2 is explained. The method according to the first embodiment can be used, for example, to manufacture motor component 1 and thus arrangement structure 2 according to the first, second, third and fourth embodiments.
[0048] In the method for manufacturing motor component 1 and thus arrangement structure 2, a lamination group 4 is provided, the lamination group having corresponding slots 5. Furthermore, in this method, a corresponding length region L is provided in the corresponding slot 5, and a winding 3 is fixed to the lamination group 4. This is achieved, for example, by the winding 3 being wound around the lamination group 4.
[0049] In a first embodiment of the method, a plastic body 14 is provided, which is constructed separately from the winding 3 and from the lamination group 4, and is manufactured independently of the lamination group 4 and the winding 3, and is made of plastic K. The method according to the first embodiment... Figure 6 The following is a schematic description. For example, the plastic body 14 is provided in the first step of the method. In the second step SR2 of the method, the plastic body 14 is placed in the corresponding groove, and thus the plastic K is placed in the corresponding groove 5.
[0050] In the third step SR3 of the method, especially since this third step immediately follows the second step SR2, and therefore after the plastic body 14 is placed in the corresponding groove 5, a deformation method is implemented by means of which the plastic body 14 deforms during its placement in the corresponding groove 5. The method is shown in... Figure 5 and 6 In the first embodiment, for example, the deformation method or includes an internal high-pressure molding method, wherein, during the period when the plastic body 14 is disposed in the corresponding groove 5, a fluid, such as a gaseous fluid, i.e., a fluid constituting a gas, is introduced into the corresponding groove 5, so that the plastic body disposed in the corresponding groove 5 is at least indirectly, and especially directly, loaded with fluid, particularly on the side of the plastic body 14 that faces away from the stacked sheets. Therefore, as in Figure 6 As described by the arrow in the third step SR3, the pressure caused by the fluid is applied, at least indirectly and especially directly, to the plastic body 14 disposed in the corresponding groove 5, thereby deforming the plastic body 14.
[0051] Depend on Figure 6As can be seen, previously, and for example in the second step SR2, the corresponding portion TB of the plastic body 14 was spaced apart from the wall region W of the stack 4, which defines the corresponding groove 5, in particular directly defining the corresponding groove, and the portion TB was disposed in the corresponding groove 5. By deforming the plastic body 14 in the corresponding groove 5 in the third step SR3, the portion TB of the plastic body 14, which was originally spaced apart from the wall region W and disposed in the corresponding groove 5, is placed in support abutment with, in particular directly, the wall region W of the stack 4, so that due to the deformation of the plastic body 14, the portion TB of the plastic body directly contacts the wall region W. Therefore, the plastic body 14 is particularly advantageously, in particular, attached to the stack 4 with a particularly large area in the corresponding groove 5, so that advantageous, effective and efficient heat exchange can be achieved between the stack and the temperature-regulating medium flowing through the temperature-regulating channel 13 through the plastic K.
[0052] In the fourth step SR4 of the method, which immediately follows the third step SR3 in time, the corresponding length region L is set in the corresponding groove 5. Therefore, the plastic K is set in the corresponding groove 5 between the stack 4 and the corresponding length region L. Thus, as in Figure 6 Through Figure 6 The temperature control channel 13 described in the enlarged description of region B is defined on the one hand by plastic K, especially directly by plastic, and on the other hand by a corresponding length region L, especially directly by the corresponding length region.
[0053] In a second embodiment of the method not described in the accompanying drawings, for example, an injection molding method is implemented, wherein, particularly in a liquid state, the plastic K is injected into a corresponding groove 5. Thus, for example, particularly in a liquid state, the plastic K is injected toward the stack 4, particularly directly toward the stack. Then, the previously liquid plastic K undergoes age hardening, for example, thus forming a solid, also simply referred to as an object, composed of the plastic K, particularly in the fully manufactured state of the motor component 1. Then, a corresponding length region L is provided in the corresponding groove, so that the plastic K is thus positioned between the corresponding length region L and the stack 4.
