Description

The The invention relates to a multi-shaft motor according to the preamble of claims 1 and 7 specified type, and an actuator according to the preamble of the claim 33 specified type.

A generic, all features of the preamble of claims 1 and 7 exhibiting multi-shaft motor is from the WO 00/05803 A1 known. The multi-shaft motor includes a number of electrical coils that cooperate with one or more stator core parts, at least two permanent magnet rotors having a coil in common. The magnetic flux of a coil has the possibility of two closed magnetic circuits with two air gaps to run. The two magnetic circuits belong to different motor shafts. To ensure a sufficient magnetic flux over the respective active permanent magnet rotor, the coil is to be interpreted correspondingly larger. The individual stator parts of the known multi-shaft motor are designed differently, which increases the number of parts. As a result, the winding and assembly is relatively cumbersome.

From the US 5,539,584 A a drive unit for a motor vehicle exterior mirror assembly is known. The generic, all features of the preamble of claim 33 having drive unit comprises any two drive motors, which are arranged mounted in an actuator with an at least two-part housing on a support, wherein the axes of rotation of the drive motors are at an angle to each other.

task The present invention is a multi-shaft motor and a To provide actuator that as simple as possible and a few Parts are constructed and those without gear means for angled successive drive tasks are suitable.

These The object is achieved by the characterizing features of claims 1, 7 and 33 solved in conjunction with their generic features.

According to the invention is for the multi-shaft motor provided that axes of rotation of at least two permanent magnet rotors and / or planes to which these axes of rotation are each arranged at an angle and in each of which at least one stator part is located, correspondingly to stand at an angle. As a result, no complicated geared activities necessary, around angularly spaced output shafts in an actuator to reach. Especially in applications where no self-locking may be present to the drive motor clutchless of a Turn back actuator to be able to has said solutions unique Advantages, e.g. across from a worm gear solution.

For the actuator is provided according to the invention, that at least one housing part with a predetermined kink, a joint or a predetermined breaking point is provided, wherein the predetermined kink, etc. of the housing part with the predetermined kink of the carrier Aligns or that the housing even the carrier is.

The under claims form advantageous developments of the invention.

In the practice become common perpendicularly juxtaposed axes of rotation required, for. B. in the drive of Air direction control devices of an air outlet nozzle in the motor vehicle. For such use cases it is appropriate if the axes of rotation of at least two permanent magnet rotors and / or Planes to which these axes of rotation are each rectangular, at least nearly standing at right angles to each other. As with air direction control devices only a small moment is necessary for their adjustment, can be low reducing reduction gears used or on reduction gear completely be waived.

If drive motors z. B. after DE 199 09 227 A1 used, then the multi-shaft motor requires at least four stator and three stator coils.

Especially it is advantageous if possible to use many identical parts, in particular by identically formed Stator. Nevertheless, different multi-shaft motor arrangements possible with these identically designed parts.

The Basic shape of the stator can be U-shaped, E-shaped or comb-shaped be. These basic shapes can also be combined with each other, whereby even more variants can be produced.

The basic concept of embodiments shown later is from the DE 199 09 227 A1 known. Here, the stator parts are preferably U-shaped and have two Statorpolschenkel which are interconnected by a Statorjoch, said ends of the stator pole legs form main poles of the multi-shaft motor. This engine concept has proven itself in practice.

For ease of mounting, in some embodiments of the multi-shaft motor, it is important that the cross-sectional area of the ends of the stator pole legs be less than or equal to the cross-sectional area of the stator pole legs. This makes it possible to wind coils in a first step and the Then mount the stator parts in it. For the same reason are also Statorpolschenkel vogesehen, which have a straight course from Statorjoch to the end of the legs.

Of the Manufacturing effort and assembly is simplified by that a coil over two stator parts is wound. This is also possible if these two stator parts standing at right angles to each other while touching each other.

Around can represent more variants coils also over a stator yoke of a first stator part and a stator pole leg be wrapped another stator. But it is cheaper to mount the stator pole leg only after the winding process, because otherwise elaborate Winding method would have to be used.

It is also possible a coil over ever to wrap a Statorpolschenkel two stator or the Stator parts with their Statorpolschenkeln after winding in it to assemble.

The same advantages as in the U-shaped design of the stator is also when using E- or comb-shaped stator parts available. By Combination of these with U-shaped Stator parts result in further variants of the multi-shaft motor.

Also E- or comb-shaped Stator parts can be formed identical, if e.g. four E- or comb-shaped stator parts for the Structure of a multi-shaft motor needed.

Like from the DE 199 09 227 A1 known increase additional poles, which consist of soft magnetic sheets and are arranged and shaped between the Statorpolschenkeln that parts of the magnetic flux from the Statorpolschenkeln are feasible to corresponding rotor poles, primarily the self-holding torque of the motor. The stator parts themselves may consist of layered laminated cores or be designed as a sintered part. In the case of sintered parts, it is also possible to form a stator part with, for example, four stator pole legs, with one pair of stator pole legs each being angled, in particular at right angles, to the rest of the pair.

Conveniently, Each coil is wound on an insulating body. It can Also, a common Isolierstoffkörper carry several coils. Especially for the winding of the stator and the insulating material is it makes sense assemblies of at least two stator parts and one insulating to add then as a compact component in one operation in a winding device can be provided with at least two stator coils. common insulating usually have a U-shaped Cross-section on, with one-piece snaps at their ends. These snap means engage behind the stator parts, so that a sufficiently strong connection is formed.

To a particularly advantageous embodiment of the invention the stator parts first wound and then kinked. This is possible by that the insulating body, the stator parts for the winding to a module holds together with at least one predetermined kink, a Joint or a predetermined breaking point is provided. To still one to ensure sufficient strength of the insulating body, is provided the insulating body with breakable, removable or otherwise manipulable stiffening agents train the at least during the winding of the assembly of stator parts and insulating material ensures that no premature kinking is possible. After the winding process these stiffeners are broken, removed or manipulated, that they can no longer counteract the kinking.

Around to enable the voltage supply of the bent stator coils conductive means are provided, in the form of wire bridges, on or injected or mounted baffles are formed, wherein it depends in particular on deformability of these conductive means. The conductive means should at least the predetermined bending, joint or predetermined breaking point electrically bridge them but can also serve a direct electrical connection to to make a plug connection.

Since usually at least two provided with an insulating body stator assemblies are available, it is helpful to assemble this after wrapping on a support. As a result, an accurate spatial allocation of the stator parts with each other and the permanent magnet rotor is achieved. Bearings for the permanent magnet rotors can also be integrated in the carrier. In order to achieve despite the carrier still an angular arrangement of the multi-shaft motor, in particular its rotor axes, it may be advantageous if the carrier is provided with a predetermined bending point, a joint or a predetermined breaking point. The carrier preferably consists of a plastic material which can be processed by injection molding. This facilitates adaptation to more demanding geometric conditions. In principle, the carrier can also consist of a conventional flat printed circuit board. The Sollknickstellen etc. the Isolierstoffkörper and the carrier should be designed to be aligned with each other to allow a precise kinking. Preferably, the crease line should therefore be partially occupied by the Isolierstoffkörpern and partially by the wearer. On the Sollknickstelle etc. in the carrier but may possibly be waived if the Carrier only a maximum of the kink, etc. extends the insulating body.

alternative or additionally to the conductive elements in or on the Isolierstoffkörpern can also the carrier Equipped in the same way with corresponding conductive elements be, wherein these conductive means must also be deformable in this case.

In order to obtain a compact unit, which is also protected from environmental influences, the multi-shaft motor should be arranged in a multi-part housing and fixed therein. It may, similarly, like from the DE 199 09 227 A1 known, a motor housing part, a gear housing part and an intermediate plate may be provided. Preferably, the intermediate plate then assumes the function of the carrier.

It is possible, too at least one housing part with a predetermined kink, a joint or a predetermined breakage level to be provided, wherein the predetermined bending point, a hinge axis or the Breaking point, in particular with the predetermined bending point of the insulating material and / or the Sollknickstelle the support should be aligned. In this version is a fully assembled and mounted in a housing and fixed multi-shaft motor still kinkable at any angle and the given installation conditions on Adjustable actuator or the actuators customizable.

It is also conceivable that a multi-shaft motor is repeatedly bent. It is advantageous in each case the possibility with only one plug, So get an electrical interface for all drive tasks. The number of permanent magnet rotors is at least theoretical arbitrary.

Around a kinking of the housing to enable allowed to There are no geometric obstacles. That's why it should casing in the area of the predetermined buckling point, or of the joint or the predetermined breaking point be formed waisted. additionally is an adapted to the bend angle clearance required should connect to the predetermined kink, etc. Preferably the free space by two by 45 ° inclined housing walls limited.

Around an accurate and permanent position assignment of the housing areas on both sides of the Sollknickstelle, etc. to ensure are locking devices and guides intended. These are preferably integral with the respective housing part educated.

Around make the wrapping process as easy as possible and at all costs Stator coils of a structural unit made of stator parts and an insulating body at the same time to be able to wrap is provided that provided connection points on the Isolierstoffkörpern are the same in the unbent state Distance, as the stator coils, having both the connection points as well as the stator coils are arranged equidistant to each other. As connecting parts serve arranged parallel pins.

Between the housing parts with each other or between the housing parts and the carrier or the intermediate plate may be provided a seal, as far as this is required. Even at higher Requirements for tightness, therefore, is a kinking of the multi-shaft motor possible.

Of the Multi-shaft motor can depending on the external wiring operated both as a step and brushless motor become. Possibly. can different permanent magnet rotors of the same multi-shaft motor also be operated according to different.
