Definitions

• the interconnection arrangement can thus be contacted with supply electronics on a first part of the busbar.
• a second part of the busbar which is formed, for example, on a switching ring segment formed by the busbar (e.g. in a common plane with the second area of the busbar)
• the interconnection arrangement can be contacted with a winding of a stator.
• the switching ring segment can be received and fixed in a housing of the interconnection arrangement.
• the first and second areas are arranged in parallel planes.
• the first area lies in a plane which is inclined by less than 1 ° (or less than 2 °, or less than 5 °) with respect to a plane of the second area.
• the planes can be aligned in the radial direction of the stator, so that, for example, contacting the interconnection arrangement with external connections can be carried out particularly easily.
• the second area can be stretched or compressed in the axial direction in order to compensate for tolerance distances between the first area of the busbar and the power connections.
• the central area is aligned in a connec tion plane, with an angle between the connection plane and the the plane of the first area deviates from a right angle.
• the value range of the angle can be defined as described above.
• the partial area comprises at least 50% of an area of the central area.
• a central region (eg less than 50% of the area of the central region) of the central region can be arranged at a 90 ° angle with respect to the plane of the first or second region, and the interconnection arrangement can nevertheless effect a length compensation.
• the interconnection arrangement can, for example, have three shaped busbars that are electrically isolated from one another for contacting three phases of the stator winding, the respective middle areas of the busbars being arranged in different, non-parallel planes.
• manufacturing tolerances and the like can be compensated for by the central regions in that the central region is correspondingly deformed in the axial and / or radial direction. Due to the deformation, forces can therefore occur which act on the interconnection or the stator.
• the central areas are therefore advantageously arranged in different planes if there are several busbars, the planes preferably not running parallel. This prevents, in particular in the radial direction, any forces occurring on the individual busbars from increasing, but from being kept low and possibly canceling out or reducing each other.
• the first area of the busbar of the circuit arrangement is arranged in a normal plane of a main axis (e.g. a rotor axis) of the stator.
• a normal vector of the plane of the first area lies parallel to the main axis.
• the elasticity of the central area of the busbar enables the first area to be moved axially by at least 1 mm, for example. For example, if the first area is shifted by up to 3 mm, only the middle area is essentially deformed.
• the invention provides, for example, an interconnection arrangement with length compensation for an electric machine.
• the middle area can cause a slight change in length of the busbar to compensate for tolerance-related spacings during the assembly of the interconnection arrangement.
• Developments of the stator and the electrical machine relate to features of developments as they are already described in connection with the interconnection arrangement be. A repeated description is therefore dispensed with and the corresponding features also apply in connection with the stator and the electrical machine as disclosed.
• a thickness D of the busbar 12 is 3 mm. In connection with the special design of the angles ⁇ and ⁇ , this results in, for example, a slight elasticity of the central area.
• the middle area 22 can have a slight spring effect, so that a slight movement (for example by 1 mm or 2 mm) of the first area 14 in the direction of a normal vector of the first area 14 in a plane parallel to the first area 14 without a substantial mechanical Tension (for example, shear force or force in the direction of a normal vector of the parallel plane) in the first area 14 and 18 or in the second area 18.
• the thickness D causes, for example, sufficient rigidity of the busbar 12 at the same time, so that the first area 14 remains positioned in a predetermined position without the action of a compressive or tensile force and can therefore be contacted easily.
