- the invention further relates to an electrical machine comprising a stator and a rotor.
- the invention relates to a method for producing a machine component in the form of a stator or a rotor for an electrical machine, comprising the steps: providing a laminated core which extends in an axial direction, a radial direction and a circumferential direction and in which a plurality of slots are arranged , wherein the grooves extend in the axial direction and the radial direction of the laminated core and are arranged next to one another and spaced apart from one another in the circumferential direction of the laminated core, providing a number of N > 2 electrical conductors, which have an insulating layer for electrically insulating the electrical conductors from each other, the insulation layer extending over the entire conductor circumference and in the axial direction of the laminated core at least over an overall height of the laminated core, arrangement of the electrical conductors in the grooves of the laminated core, and contacting of the electrical conductors.
- An electrical machine can preferably also include a rotor which, for example, can be arranged in a rotationally fixed manner on a rotatable shaft.
- a rotor which, for example, can be arranged in a rotationally fixed manner on a rotatable shaft.
- the stator can also be used without a rotor to generate a rotating field.
- Stators for electric motors include electric coils, which are designed in the form of windings around an electrically and magnetically conductive core and, when current flows through the coils, generate a magnetic field in the stator core that is required to drive the electric motor.
- These windings can be produced, for example, by inserting U-shaped conductor elements or bar-shaped conductor elements into the stator core and connecting the conductor elements provided to form windings.
- Usually several electrical conductors are arranged per slot.
- EP3 043 355 A1 describes electrical conductors with an outer insulating layer which is formed from a thermoplastic material. A duroplastic layer, which is thinner than the thermoplastic layer, is arranged between the conductors.
- a stator for an electrical machine is known from WO 2019/227115 A1, in which the insulation layer comprises a thermoplastic high-performance polymer which is continuous in the circumferential and radial direction and is molded directly onto the electrical conductor, the insulation layer having a total circumferential layer thickness at least in the circumferential direction which is at least 1.5 times to 3 times a total radial layer thickness in the radial direction of the respective electrical conductor.
- the object of the present invention is to improve the efficiency of an electrical machine.
- the object of the invention is achieved with the machine component mentioned at the outset, in which it is provided that at least one of the electrical conductors arranged per slot is formed by a number n subconductors, the subconductors being arranged running parallel to one another at least in the slots, and through an intermediate insulating layer are electrically insulated from each other, wherein a layer thickness of the intermediate insulating layer is smaller than a layer thickness of the insulating layer between the electrical conductors in the radial direction of the slots.

- the advantage here is that for a given number of turns of the electrical winding, the eddy current loss in the winding can be reduced by dividing at least one of the electrical conductors into a plurality of subconductors.
- a thin intermediate insulating layer By using a thin intermediate insulating layer, it is possible to avoid an excessive reduction in the fill factor of the slots with the electrical conductors.
- the effectiveness of the machine component or the electrical machine equipped with it can be improved by taking the necessary measures.
- the number 1 of subconductors per electrical conductor is selected from a range of 2 to 5 and/or that the number of subconductors per slot is selected from a range of 2*N up to 5*N.
- the cost of manufacturing the machine component is excessively increased on the one hand, and on the other hand the slack factor of the slots is reduced too much due to the increase in space required for an additional intermediate insulating layer, so that the number of subconductors do not lead to a further increase in efficiency (to the desired extent) leads.
- each of the N electrical conductors is subdivided into subconductors, so that the effects mentioned can be realized for each of the electrical conductors arranged in the slots.
- a layer thickness of the intermediate insulating layer is between 1% and 20% of the maximum layer thickness of the insulating layer.
- a layer thickness of less than 1% of the maximum layer thickness of the insulation layer the insulating effect of the electrical insulation between the sub-conductors is reduced.

- a ratio of the subconductor height to the subconductor width can be selected, for example, from a range from 1/2 to 1/8 with two subconductors per conductor and from 1/4 to 1/16 with four subconductors.
- the intermediate insulation layer consists of the material of the insulation layer.
- the intermediate insulation layer consists of a material that differs from the material of the insulation layer. The layer thickness of the intermediate insulation layer can thus optionally be reduced in comparison to an intermediate insulation layer made from the material of the insulation layer, with which the slot filling factor can be improved.
- the electrical conductors have a conductor longitudinal axis
- the subconductors have a roof pitch adjoining an axial end face of the laminated core, in which they rotate by an angle of between 170° and 190°, preferably by 180° , Are rotated about the longitudinal axis 25 of the conductor. Due to the rotation, the subconductors can be shortened in relation to one another. This in turn enables the same subconductors to be arranged in the slots at different radial heights, which means that circulating currents between parallel branches in the slots can be better prevented.

For example, it can be provided that the insulation layer 14 tapers (additionally) at the transition to the intermediate insulation layer 18, as can be seen from FIG. If, on the other hand, the insulation layer 14 is subsequently applied to the package of subconductors 17, this area can also be provided with a comparatively thicker insulation layer 14.

However, it is also possible that the or at least some of the subconductors 17 of an electrical conductor 10 have a different subconductor width 23 and/or different subconductor height 24 than one another. For example, the sub-conductors 17 of an electrical conductor 10 can be thinner or thicker in the radial direction 7, in relation to the radially innermost sub-conductor 17 of this electrical conductor 10.

- This can be achieved, for example, by holding and supporting the subconductors 17 in its first and second sections, then performing a pivoting bending or folding movement between the first and second sections of the subconductors 17 by the angle of rotation.
- a relative shortening of the height of the subconductors 17 in the direction of the conductor longitudinal axis 25 can thus be achieved, so that when the electrical conductors 10 re-enter the following groove 9 (Fig. 4 shows the area in the circumferential direction 8 of the laminated core 5 between two grooves 9), the subconductors 17 exchange the radial height in the groove 9 without the subconductors 17 ultimately becoming too long when viewed over the entire winding.

- the method also includes other customary steps, such as for example welding the electrical conductor 10 if these are in the form of I-pins or hairpins. Since these process steps are known, reference is made to the relevant prior art for further details.
- the electrical conductor 10 is not in the form of a pin, but instead is formed continuously over the length of the winding from one-piece sub-conductors 17 and optionally one-piece conductors 10 .
- the exemplary embodiments show possible embodiment variants of the electrical machine 1 or of the machine component 2, 3, it being noted at this point that combinations of the individual embodiment variants with one another are also possible.
