Definitions
- the present invention relates to a device for turning current, in particular a commutator, and a method for producing such a device.
- Such devices are used in particular in electric motors and power generators, for example for power tools, actuators or fuel pumps.
- a plug-in commutator is known from DE 195 30 051 A1, in which the individual commutator segments are inserted into an assembly basket and then with the formation of the support body Molding compound are injected. This is followed by further processing and testing steps in order to meet the requirements for the accuracy of the geometric dimensions of the commutator and for its stability.
- a commutator for a miniature electric motor and a method for its production are known, in which a desired number of commutator plates are attached to a lateral surface of a core at certain angular ranges with the aid of an adhesive.
- the invention is therefore based on the problem of providing a commutator which has a high degree of accuracy with regard to its geometric dimensions and a high long-term stability and is easy to produce.
- the segments on the support body can be fixed by means of a connecting means arranged essentially between the support body and the segments.
- the support body is usually made of an electrically insulating material, in particular a plastic such as a thermoset, a thermoplastic or a ceramic.
- a metallic support body can also be considered, for example made of aluminum, the surface of which is preferably provided with an electrically insulating coating, for example a lacquer coating or a metal oxide layer, which can also be produced by oxidation of the metallic support body.
- the support body can also be constructed in two or more layers, in particular have an elastic inner hub which is surrounded by a temperature-stable outer shell on which the segments can be fixed.
- the elastic inner cover provides the necessary press fit for attaching the commutator to the motor axis.
- the commutator segments generally consist of copper or a copper compound, alternatively other materials can also be considered in accordance with the requirements regarding conductivity, temperature stability and chemical resistance.
- the connecting means is preferably arranged in layers between the segments and the support body and can, for example, be attachable to the support body and / or to the segments before being fixed.
- the support body and the segments have cooperating means for positioning and aligning the segments with respect to the support body. These can be realized by point, line or sheet-like projections and corresponding recesses on the support body or on the segments.
- the segments can have web-shaped projections which can be inserted into corresponding grooves, which are aligned parallel to the axis of rotation, on the peripheral surface of the support body.
- webs oriented in the radial direction can engage in corresponding recesses or grooves on the associated segment on an end face, or the cylindrical support body can have an axially projecting and preferably have a circumferential continuous projection, which ensures centering of the segment disc to be fixed on the end face, which can then be divided into individual commutator segments which are electrically insulated from one another.
- the connecting means is an adhesive layer
- this can be filled with appropriate additives in accordance with the electrical and / or thermal requirements.
- a ceramic filler can, for example, reduce the coefficient of thermal expansion of the adhesive layer.
- An electrically conductive, in particular metallic filler, for example based on Ag, Cu or Ni, can be used to produce an electrically conductive connection between the segment and the support body, for example if, in the case of a flat commutator, the support body comprises electrically conductive, segment-shaped connecting tracks .
- the fillers can in particular one
- the distance between the commutator segments and the support body and thus the thickness of the adhesive layer preferably by means of spherical fillers, in particular glass or ceramic balls.
- the layer thickness is, for example, between 20 and 250 ⁇ m, preferably between 50 and 100 ⁇ m.
- the layer thickness can also be predeterminable by spacers which are preferably formed in one piece from the support body or the commutator segments, for example by means of correspondingly punctiform, linear or planar projections.
- the adhesive should be selected or treated in such a way that it absorbs as little moisture as possible after curing, in particular forms a permanent, firm bond with copper and is dimensionally stable even under mechanical and / or thermal stress.
- the connecting means is a solder or welding layer
- the commutator has a particularly high temperature stability and chemical resistance.
- Low-melting soft, hard or glass solders are preferred, for example low-melting lead / tin solders or glass solders with a high proportion of lead oxide.
- a particularly low connection temperature is achieved by ultrasonic or friction welding.
- the segments and the supporting body have non-positively interacting anchor and receiving means
- the segments can be inserted into the supporting body and a sufficiently stable clamp connection is ensured by the resiliently acting anchor and receiving means.
- the segments can still be fixed on the support body by the connecting means.
- Both the segments and the support body can have only anchor means or only receiving means or a combination of anchor and receiving means. It is only essential that an anchor or receiving means of the segment interacts with a receiving or anchor means of the supporting body.
- the segments can be inserted or clipped into the support body in the radial direction, for example in the case of a drum commutator, or can be inserted axially, for example, in a face of the support body in the case of a plan commutator.
- the segments are positioned and aligned.
- the means for positioning and aligning preferably extend parallel to the axis of rotation along a circumferential surface or radially to the axis of rotation along an end face of the support body.
- All suitable shapes can be considered for the means for positioning and aligning, in particular webs with a triangular, square, semicircular or dovetail cross section.
- Particularly suitable for anchoring are cross-sectional shapes which expand in depth and are in particular provided with a tip for easy insertion.
- the segments are fixed on the support body by means of a connecting means arranged essentially between the support body and the segments.
- the support body as a whole can be placed in a connecting agent immersion bath before the segments are fixed.
- the segments can also be provided with the connecting means at least on their surface facing the support body. If necessary, the surfaces of the support body and / or the segments must be cleaned and / or provided with an adhesion promoter before the connecting means is attached.
- the surfaces can preferably be conditioned in a vacuum process, for example in an ion or plasma vacuum process. Due to the surface treatment, there is also sufficient aging and corrosion resistance of the connecting layer to the stresses during later use and / or a uniform one
- Means for positioning and aligning the segments are provided, the shape of which is designed such that positioning and alignment takes place automatically when the segments are fed in, for example by grooves of triangular cross section in the support body, are inserted into the corresponding cross-sectional webs of the segments.
- the connecting means can be inserted into the groove as an adhesive strand, for example, before being fed in.
- the connecting means arranged between the support body and the segments can be omitted.
- the fixing is carried out only by means of the anchor and receiving means arriving at a clamping connection.
- an adhesive, soldering or welding layer is particularly suitable for this.
- the maximum temperature during further processing can be briefly up to about 300 ° C.
- an adhesive layer should be cured at the lowest possible temperature, for example in the temperature range between 50 and 250 ° C., preferably between 170 and 200 ° C.
- the segments are fed to the support body one after the other, this can be done by gradually rotating the support body about its axis of rotation and piece-wise positioning of the segments or by rolling the support body onto it, for example in a strip composite existing segments.
- the connection between the support body and the respective segment can either take place immediately after the feeding or finally for all supplied segments together, for example by enclosing the support body equipped with segments with a pressing and / or heating tongs.
- Fixing the segments on the support body ensures. This can be done, for example, by pressing the segments into the support body, in particular by pushing the anchoring and receiving means into one another, and / or by heating the segments to melt the connecting means and produce a connecting layer.
