- the invention is therefore based on the object to provide a weight-reduced housing an electric machine or electric motor, which is inexpensive to manufacture and allows easy installation.
- a method for producing a housing for an electrical machine from at least two shell parts, each of which covers at least part of the circumference is characterized in that at least one of the shell parts is produced from sheet metal by at least one deformation, and in that the metal sheet before, is provided during or after the forming at least partially with a plastic layer.
- the shell parts are manufactured in such a way that they cover at least part of the circumference of the engine form housing and thus cover at least a part of the stator of the electric motor.
- metallic sheets in particular steel sheets are used, which were provided at least on one side at least partially with a plastic layer.
- the sheets, in particular steel sheets instead of partially also be coated over the entire surface with a plastic layer.
- coated sheets are then formed into the shape of the shell parts, in particular by deep drawing, pressing, punching and / or bending operations, wherein they comprise at least part of the peripheral surface of the later motor housing, and preferably at least a part of at least one end face of the motor housing ,
- the shell parts cover even areas of the circumference, in particular 120 ° or 180 °, whereby symmetries used and the number of parts and number of variants, that is number of different parts, can be kept low.
- an at least partial covering of a circumferential region of more than 180 ° is preferred, provided that the remaining clear width of the opening corresponds to the diameter of the stator or the stator can be inserted by purely elastic deformation of the shell part. As a result, the assembly and positioning of the stator can be simplified.
- the functional elements are also made of plastic, preferably of the same or similar plastic as the plastic layer, in particular a thermoplastic, preferably a polyamide, such as PA, PA6, PA66, PA610, or alternatively PES, PEI, PPSU and PPS and fiber-reinforced plastics, whereby the connection with the plastic layer is simplified, and the required temperature resistance is realized.
- the application can be done for example by injection molding, laminating, compression molding, tape laying or prefabricated moldings that are glued or welded.
- the application preferably takes place before the forming, in particular if they are provided on the inside, since this simplifies manufacture.
- functional elements such as stiffeners, bearing or support elements whose Form is given only after the forming or serve to reinforce the shell part are applied after the forming.
- inventive methods are characterized in that the functional elements are applied in one step together with the plastic layer before, during or after the forming in one piece. By simultaneous application, the required manufacturing steps are reduced and it is ensured a secure connection of the functional elements.
- the functional elements include a temperature control unit.
- the tempering unit may be designed as a cooling channel, heat conducting elements, such as particles, heat pipe or the like, or cooling rib.
- the shell parts of the motor housing are provided, for example, with cooling channels as functional elements.
- the cooling channels can be mounted on the inside and / or outside of the shell parts on or together with the plastic layer.
- the method is characterized in that flange-like connecting regions for connecting the shell parts to one another are produced by deformation and / or application to the sheet metal on the shell parts.
- the connection between the shell parts is preferably made by a flange connection, via which the parts are connected to one another, in particular screwed.
- at least one of the surfaces of the shell parts that come into contact with one another has the plastic layer or is formed from plastic.
- the flange portion is deformed such that the plastic layer is within the flange connection to be formed or the flange is a functional element which is applied to the sheet.
- the method is characterized in that at least in regions an additional metal part is applied on the side of the plastic layer.
- the additional metal part can be used for local reinforcement, temperature control or shielding. serve or be provided for example as a short-circuit ring of the electric machine.
- the sheet is formed of a plurality of mutually electrically insulated metal layers. This reduces the losses, e.g. reduced by eddy currents, and improved electromagnetic shielding and mechanical / acoustic damping.
- the sheet is preferably made of steel, in particular of a low-permeability steel material (according to standard SEW 390), preferably an austenitic high-Mn steel, X-IP steel and stainless steel.

- Embodiments of the housing are characterized in that the shell parts have functional elements provided on the plastic layer. These functional elements may be bearings, stops, positioning aids, temperature control units (e.g., cooling channels), and the like.
- motor housing according to the invention are characterized in that the plastic layer and the functional elements are integrally formed.
- the connecting regions are formed as flanges, in which the plastic layer and / or functional elements of the respective shell parts are interconnected.
- the contact between the Shell parts thus takes place via at least one plastic layer or via functional elements designed as plastic flanges.
- Embodiments of the housing are characterized in that the functional elements have at least one tempering unit.
- housings are characterized in that at least partially an additional metal part is provided on the side of the plastic layer.
