Definitions
- the present invention relates to an external rotor rotor device with a rotor housing for at least one rotor and with at least one sensor magnet provided on the rotor housing, the sensor magnet being able to be arranged in sensory correlation and in a predefinable relative position relative to the rotor.
- the invention relates to a device for the particularly advantageous arrangement or alignment of sensor magnets relative to the rotor or rotor housing.
- the present invention also relates to the use of an additional housing component for integrating sensors into the housing.
- the invention relates to a device according to the preamble of the independent claim.
- sensors In the case of many rotating devices with rotors, it is advantageous to integrate sensors. For example, even with external rotor rotors (external rotor design of rotating electrical machines) it can be very advantageous if sensors are provided which, for example, enable operating parameters to be monitored by means of a magnetic field and / or to generate measured values. In particular, it has already been tried to glue the sensors to the outer housing of rotors with index magnets or similar sensors. Not least because of the measurement technology used, it is desirable to be able to position the respective sensor on the housing as precisely and robustly as possible.
- the object is to provide a device with which sensors, in particular sensor magnets, can be fixed in a particularly expedient manner on rotors, in particular external rotor rotors.
- the object is to provide an external rotor rotor device with an integrated magnetic sensor system in such a way that the sensor system can be aligned and / or positioned particularly precisely, in particular relative to bores in the rotor housing.
- An external rotor rotor device is provided with a rotor housing designed to accommodate at least one rotor and with at least one sensor magnet provided on the rotor housing, the sensor magnet being arranged / can be arranged in sensory correlation with and in a predefinable relative position relative to the rotor.
- the external rotor rotor device has at least one ring which is integrally molded onto the rotor housing, the ring having at least one pocket (sensor cavity) which is designed to accommodate the sensor magnet, the sensor magnet being / can be arranged in the pocket in this way and wherein the ring is arranged / can be arranged in a predefinable relative position relative to the rotor on / in the rotor housing in such a way that the relative position of the sensor magnet relative to the rotor is predefined in at least one spatial direction by the integral molding, in particular at least with respect to the radial direction and also with respect to the circumferential direction and / or the axial direction.
- the sensor system can also be integrated in a particularly precise and robust manner.
- the pocket in particular the relative radial position and also the alignment of the sensor system (in particular the north-south axis) can be determined can be defined in a comparatively exact and reproducible manner. Last but not least, cost advantages can also be realized. Any assembly tolerances can be minimized.
- the position of the rotor can be predefined by the rotor housing, in particular via at least one bore which defines an axis of rotation.
- a relative orientation and arrangement relative to the housing can therefore imply a relative orientation and arrangement relative to the rotor, and vice versa.
- the invention is based on the concept of integrating sensors into the housing without having to modify the housing. Rather, the sensor system can be integrated (or can be integrated) into an initially separate ring, which is connected to the housing, preferably by primary molding, preferably without the use of any adhesives. In particular, even in the case of separate supply chains or manufacturing processes, this provides the option of providing the sensor with the ring on the one hand and providing the housing on the other hand in order to then have both components (especially in the sense of a "marriage" as in automobile production) at the end of the manufacturing process to unite with each other.
- the sensors are preferably integrated on the outside of the housing. Last but not least, this arrangement also facilitates the implementation of an injection molding process.
- An external rotor rotor device is generally to be understood as a rotating electrical machine with an external rotor (stator further inside than rotor).
- An external rotor is to be understood in particular as a design of rotating electrical machines (in particular generator or electric motor) in which the stationary part (stator) is located on the inside of the moving part (rotor, “rotor”).
- Application examples are, for example, commutated DC motors or asynchronous motors with squirrel cage rotors, which are used, for example, as axial fans, dynamos, ceiling fans, centrifugal motors, direct drives for computer hardware or the like.
- Sensor magnet technology is mentioned as an example of sensor technology.
- the invention can be transferred to other sensor technologies.
- the pocket can also be designed for any other sensor, be it with regard to its size and geometry, or with regard to its arrangement relative to the rotor or to the housing.
- the invention can expand the range of applications of the rotor devices.
- the sensor system or its integration is less sensitive to temperature fluctuations or aging effects or external influences such as UV radiation.
- the use of glue or adhesives can be completely dispensed with. A detachment of the sensors from the housing can be ruled out with very good certainty.
- the present invention also enables the sensor magnet to be aligned very precisely in the axial and radial directions (in particular also with regard to a north-south axis of the magnet), in particular relative to bores in the housing. This also favors a robust and operationally reliable overall arrangement that can be optimized in terms of control / regulation technology over a long period of use.
- the integration of the sensor system into the rotor housing can be ensured particularly advantageously by means of a ring geometry for the additional (housing) component, for example with regard to an already predetermined cylindrical geometry of the rotor housing.
- the person skilled in the art can deviate from the ring shape or use other shapes for this additional (housing) component, by means of which the sensor system can also be provided in a pocket or similar cavity, and by means of which a cohesive molding or integral connection of the both housing components (rotor housing and ring or equivalent additional components) can be realized in a comparable manner.
- the term "ring” is not to be understood as being geometrically limiting, but as an example specifically in the case described for an at least approximately cylindrical housing.
- the ring has an inner circumferential surface, by means of which the ring is integrally molded onto an outer circumferential surface of the rotor housing.
- Such an interface also provides the advantage of high dimensional accuracy, in particular with cylindrical surfaces or with very slightly conically inclined surfaces.
- the ring and the rotor housing can have geometrically corresponding lateral surfaces, by means of which a materially bonded interface is provided, in particular over the entire circumference.
- a materially bonded interface is defined between the ring and the rotor housing, in particular over the entire circumference, at which the material bond between the ring and the rotor housing is ensured, in particular on mutually fully contacting lateral surfaces. This also provides good robustness and a secure fit or a good, resilient connection at this interface.
- a materially bonded interface can be defined between the ring and the rotor housing, which interface is set up for a material bond by injection molding or injection molding, the materially bonded interface being defined on an outside of the rotor housing.
- injection molding large quantities can be realized in a short time, especially with cost advantages.
- the external rotor rotor device is designed to integrate the sensor system into the housing by adding a further housing component (ring) without having to modify the housing for this purpose. Rather, the sensor system can be integrated (or subsequently integrated) in an initially separate ring (or geometrically different alternative component with the same integration functionality), which is connected to the housing, preferably by molding, preferably without the use of any adhesives.
- the ring and the rotor housing can have geometrically corresponding lateral surfaces, by means of which a fully circumferential cohesive interface is provided, which has a maximum degree of mold separation of 0.1. Last but not least, this arrangement favors an indirect positioning of the sensors.
- the degree of mold separation can relate specifically to the two housing components.
- a surface for the interface can be defined on the rotor housing, for example at a lower edge, and the ring is connected to the rotor housing, for example, in the same plane with the lower edge of the rotor housing. Only the circumferential position needs to be set. The height position can thus already be predefined by the geometry of the housing.
- the external rotor rotor device is set up to integrate the sensor system into the rotor housing by adding a further housing component (in particular with a ring geometry or a similar geometry), in particular provided by the ring.
- a further housing component in particular with a ring geometry or a similar geometry
- This not only simplifies the alignment, but also the attachment of the sensors.
- the invention is also based on the concept of providing a much larger fastening interface by means of the additional housing component (ring) than would be possible via the sensor alone.
- the ring is integrally molded onto the rotor housing by injection molding. This also enables a large-area interface and a comparatively robust connection in combination with good angular accuracy and level alignment, especially if the ring also defines the underside of the housing.
- the ring or the additional housing component can be materially connected to the rotor housing without an additional material connection component, in particular without adhesive or glue, in particular only with the inclusion of the substance or the substances or materials of the ring and the rotor housing. This provides a robust interface and can also maximize long-term service life and operational reliability.
- the ring can, in particular, be connected to the rotor housing in a materially bonded manner over its entire circumference by means of a primary molding process.
- the ring can in particular be physically (non-chemically) connected to the rotor housing, that is to say without a chemical reaction and without additional chemical connecting means.
- the ring can be connected to the rotor housing by plasticizing material of the ring and / or rotor housing, in particular by applying pressure.
- the rotor housing has at least one bore, in particular a bore arranged in an end face section of the rotor housing, the pocket or the sensor magnet being arranged in a radially aligned arrangement with the at least one bore. This also favors an exact and metrologically optimized integration of the sensors.
- the pocket houses the sensor magnet on at least four or five sides, in the sense of a boundary or partition. Last but not least, this also provides good protection against external influences. A comparatively exact alignment of the sensor can also take place by means of the pocket.
- the inner geometry of the pocket can be configured geometrically and also with regard to the dimensions to correspond to the sensor magnet, in particular in the sense of a negative shape. The sensor can thus be embedded in the pocket and therefore also very well supported. Alignment tolerances can be minimized.
- the pocket houses the sensor magnet on five sides, the sixth side (in particular the underside of the ring or rotor housing) being a side that is subsequently closed after the formation of the ring, in particular a side that is closed by ultrasonic welding and / or hot stamping.
- the rotor housing and / or the ring are made of plastic material. This can also enable simple application of the advantageous manufacturing steps described here.
- the rotor housing and ring are made of the same material.
- an additional housing component in particular in the form of a ring, in an external rotor rotor device, in particular in an external rotor rotor device described above, to provide a receiving cavity (pocket) for sensors integrated in a rotor housing of the external rotor rotor device, in particular for at least a sensor magnet, wherein the additional housing component is set up for a primary molding process for integrally molding the housing component on the rotor housing with the receiving cavity in a predefined relative position relative to the rotor housing, in particular is set up for a molding process and is provided in the form of a solid housing component made of plastic Material.
- the additional housing component becomes part of the rotor housing, in particular in that the additional housing component forms a collar of the rotor housing.
- the additional housing component can be integrated into the housing or molded onto the housing, in particular by means of an original molding process in the form of an injection molding process.
- an external rotor rotor device with a rotor housing designed to accommodate at least one rotor and with at least one sensor magnet provided on the rotor housing, the sensor magnet being arranged / can be arranged in sensory correlation with and in a predefinable relative position relative to the rotor
- the External rotor rotor device has at least one ring which is integrally molded onto the rotor housing, the ring having at least one pocket which is designed to receive the sensor magnet, the sensor magnet in this way in the pocket is arranged / can be arranged and wherein the ring is arranged / can be arranged in a predefinable relative position relative to the rotor on / in the rotor housing such that the relative position of the sensor magnet relative to the rotor is predefined in at least one spatial direction by the integral molding, in particular at least with regard to the radial direction as also with regard to the circumferential direction and / or the axial direction, the ring and
- an external rotor rotor device with sensors integrated into the rotor housing in particular by an external rotor rotor device described above, produced by integrally molding an additional housing component in the form of a ring with at least one pocket (receiving cavity) for the sensors, in particular the sensor magnet, onto the Rotor housing and thereby forming an integral housing part at least from the rotor housing and the ring, in particular by connecting the ring to an outer jacket surface of the rotor housing by primary molding in the form of injection molding (in particular by so-called “injection mol ding”).
- the pocket can, for example, also be individually optimized for a particular application in a relative position within the ring (for example, as far radially inward as possible for a short measuring distance to the rotor), not least thanks to the solid design of the ring. Whether / when a sensor magnet is inserted into the pocket can be determined individually for a particular application. For example, after the original molding or injection molding of the ring, the sensor magnet is inserted into the pocket, and the pocket is then closed, in particular hermetically sealed in all spatial directions (preferably only one side, in particular the underside, of the pocket must be closed).
- the ring attached to the rotor housing in a materially bonded manner can form a collar of the housing, in particular on the lower edge of the housing.
- the pocket is closed after the sensor system or the sensor magnet has been inserted, in particular by using ultrasonic welding and / or hot stamping.
- This process step can optionally be carried out in combination with the original molding or injection molding, optionally also independently of it.
- the pocket in particular on an underside of the pocket, can optionally also be closed by other methods.
- the closure is only used to seal off the pocket and possibly to avoid losing the sensor magnet, so that the skilled person can use the method to close the bag can be chosen largely freely and individually for a particular application.
- the way of closing also depends on whether / when the sensor magnet is / will be arranged in the pocket.
- the closure of the pocket can optionally also provide a reversible closure, in particular if the pocket is to remain accessible if necessary.
- an index magnet rotor device has heretofore been manufactured, for example, by the following method:
- the at least one magnet is positioned or fixed by means of a device
- the device is carefully removed, in particular so as not to influence the desired relative position of the magnet relative to the circumferential surface;
- the at least one magnet e.g. block magnet
- -UV light for example, can be used for curing.
- Such a procedure can, however, have the disadvantage that the sensor magnet cannot be positioned exactly, that fastening takes a comparatively long time, and / or that the optimal process parameters are not adhered to during gluing and curing, e.g. due to temperature and / or fluctuations in humidity.
- the above-mentioned object is also achieved by a method for producing an external rotor rotor device with sensors integrated into the housing, in particular an external rotor rotor device described above, with at least one sensor magnet in sensory correlation with the rotor and in a predefinable relative position on a rotor housing for receiving at least one rotor of the external rotor rotor device is arranged relative to the rotor, wherein at least one additional housing component, in particular in the form of a ring, is integrally molded onto the rotor housing, the additional housing component having at least one pocket in which the sensor magnet is received or can be received, the additional housing component (and thus also the pocket) is arranged in a predefinable relative position relative to the rotor on / in the rotor housing by the molding in such a way that the relative position of the pocket or of the sensor magnet relative to the Rotor is predefined in at least one spatial direction by the integral molding, in particular at least with respect to the radial direction and also with respect
- the molding can be done in particular by one of the following methods: thermoset injection molding, elastomer injection molding, multi-component injection molding, in-mold Injection molding, hot stamping or injection molding or swelling flow stamping, powder injection molding, extrusion injection molding.
- the method also includes inserting the sensor magnet and / or closing the pocket, in particular by ultrasonic welding and / or hot stamping.

- the lateral surfaces 15a, 20a which contact one another or are fused or connected to one another are identified with reference to the dotted line (which is intended to symbolize the materially bonded interface 18).
