Definitions
- the present invention relates to a contacting unit for an electric motor, an electric motor and a vehicle, in particular a vehicle driven by an electric motor with such a contacting unit and/or such an electric motor.
- An electric motor for example a permanently excited synchronous machine, PSM of a vehicle, can comprise a stator housing and a rotor arranged in the stator housing.
- an electronics housing with electronics can be arranged on the stator housing, with the control being carried out by means of the electronics.
- a time-varying magnetic field induces a vortex-shaped electric field around magnetic flux lines in the stator housing.
- This electric field drives ring-shaped currents through the stator housing, so-called eddy currents. These flow better the higher the frequency of the magnetic field and the conductivity of the stator housing.
- the eddy currents generate a magnetic field, the so-called reaction field. Inside the vortex, this is directed opposite to the external magnetic field and weakens it. As the frequency increases, the induction becomes stronger because the change in the magnetic flux becomes greater. Even a small area penetrated by the magnetic field is enough to generate sufficient eddy currents.
- the current density increases towards the edge of the stator housing, as does the magnetic field strength, which is made up of the external field and the reaction field. This process is called current displacement.
- the current At a sufficiently high frequency, the current only flows over the outer circumference of the stator housing (skin effect) and an electrodynamic shield is formed.
- Openings in this shield are caused by ventilation openings and housing joints without seals, among other things, which leads to a reduced shielding effect. Since the current induced by the alternating field can no longer flow unhindered, slot antennas can form. Due to the design, continuous contact between the stator housing and the electronics housing cannot be guaranteed, so that cavities or air resistance are present between the stator housing and the electronics housing. This air resistance can also lead to the disadvantages described above.
- a contacting unit for an electric motor wherein the contacting unit can be arranged between two mutually facing contact surfaces of the electric motor, in particular a stator housing of the electric motor and an electronics housing with electronics for controlling the electric motor.
- the contacting unit comprises a base body and at least a first elastically deformable spring element, wherein the base body is designed such that, in a state arranged between the two contact surfaces, it is or can be spaced apart from at least a first of the two contact surfaces, and the first spring element extends or can be extended from the base body in the direction of the first contact surface in the state of the base body arranged between the two contact surfaces, in particular in an arranged state of the electronics housing on the stator housing.

- the proposed contacting unit can be arranged and/or positioned on a corresponding contact surface of the stator housing before the electronics housing is arranged on and/or on the stator housing.
- the base body can rest on the (second) contact surface of the stator housing.
- the at least one first spring element can extend away from the base body in such a way that when the electronics housing is arranged on the stator housing, the spring element is bent and/or bendable.
- the first spring element is in contact with the (first) contact surface of the electronics housing and the contacting unit represents an electrically conductive connection between the two contact surfaces.
- the contacting unit can consist of metal and/or one or more electrically conductive materials. Such a material can be or comprise high-strength stainless steel.
- the contacting unit can be coated to conduct currents, in particular with nickel.
- the contacting unit can consist of a metal and/or one or more electrically conductive materials that have a low electrical resistance. Accordingly, a low alternating resistance can be provided between the stator housing and the electronics housing and the current lines can be guided via the contacting unit.
- the electric motor can be a permanently excited synchronous machine, PSM, a three-phase asynchronous machine, ASM, a permanent magnet synchronous motor, PMSM or a similar electric machine which has a stator housing and a rotor, wherein a torque is generated by a power supply to the electric machine by means of the stator housing and the rotor.

- the first spring element is elastically deformable.
- the first spring element and/or each further spring element described are designed in such a way that they have elasticity, wherein the elasticity, in particular through a suitable choice of the material of the spring elements, enables switching between the original state and the deformed state.
- the two contact surfaces of the stator housing and electronics housing can have a predetermined distance between them when the electronics housing is arranged on the stator housing. This predetermined distance can be due to the design.
- the electronics housing can be attached to the stator housing using screws, for example.
- the electronics housing can be arranged on the stator housing in such a way that a weight force of the electronics housing already ensures that the electronics housing rests on the stator housing.
- a position of the electronics housing can be secured using the screws and/or an additional contact force for pressing the electronics housing onto the stator housing can be used.
- a weight force of the electronics housing and/or the contact force can act on the spring element(s) between the two contact surfaces of the stator housing and the electronics housing, whereby the spring element(s) are deformed and change from the original state (rest state) to the deformed state.

- the recesses 111 can have an inner contour that corresponds to and/or is modeled on an outer contour of the first spring elements 120, 120'. According to Fig.
- the recesses 111 are designed in such a way that when the spring elements 120, 120' are bent into the plane of the base body 110, there would be no contact between the spring elements 120, 120' and the base body 110. Furthermore, the Base body 110 must be at least partially spaced from the first spring elements 120, 120'.
- the spring elements 120, 120' extend upwards from the base body 110 in the direction of the image.
- the spring elements 120, 120' are at least partially curved at their proximal end sections on the base body.
- a distal end section of the spring elements 120, 120' is also curved.
- the proximal and distal end sections are connected to one another by means of a straight (middle) section.

This spacing increases an alternating current resistance between the electronics housing 202 and the stator housing 201, which, as mentioned at the beginning, is disadvantageous.
