Definitions
- Permanent magnet rotor with closed by means of an adhesive film receiving pockets for the permanent magnets
- the invention relates to a permanent magnet rotor, which has a rotor shaft, a rotor packet fixed to the rotor shaft, receiving pockets provided in the rotor assembly, and permanent magnets positioned in the receiving pockets.
- a permanent magnet synchronous machine with a laminated layer of laminations rotor assembly is known, are embedded in the permanent magnets.
- At least one magnetic flux barrier is provided at least between a recess for receiving a permanent magnet consisting of at least one magnetic plate and the air gap of the synchronous machine.
- the recesses are shaped so that in addition to a fixation of the permanent magnets also result scattering edges.
- Permanent magnets are introduced. Between adjacent recesses extending in the radial direction webs are provided. There are thin bridges between the outer edges of the recesses and the outer circumference of the rotor core. By pressing in the bridges and the consequent deformation of the webs extending in the radial direction, the permanent magnets are fixed in the recesses.
- the object of the invention is to develop a permanent magnet rotor, which has a rotor shaft, a rotor shaft fixed to the rotor shaft, receiving pockets provided in the rotor core and permanent magnets positioned in the receiving pockets, in such a way that the attachment of the permanent magnets in the receiving pockets is simplified.
- the advantages of a permanent magnet rotor according to the invention are that the attachment of the permanent magnets in the receiving pockets of the rotor core can be done very easily. Not every permanent magnet has to be fixed individually in the respective receiving pocket. Rather, the application of a single adhesive film per end side of the rotor assembly is sufficient to fix all permanent magnets of a permanent magnet rotor.
- the use of the claimed adhesive film further achieves a tight closure of the receiving pockets, so that reliable protection against the penetration of particles into the receiving pockets is provided during operation of the rotor and it is also ensured that no particles can be ejected from the receiving pockets , Furthermore, a protection of the permanent magnets from corrosion is achieved by the use of an adhesive film. Moreover, the adhesive film also fixes those rotor parts which lie between the outer radial edges of the receiving pockets and the outer circumference of the rotor. Furthermore, these rotor parts located between the outer radial edges of the receiving pockets and the outer circumference of the rotor are protected from damage by the claimed adhesive film during assembly and when dismantling the entire rotor. Finally, the mass imbalance is reduced. Further advantageous features of the invention will become apparent from the following exemplary explanation with reference to the drawings. It shows
- FIG. 1 is a longitudinal sectional view of a permanent magnet rotor according to the invention
- FIG. 2 shows a view of the permanent magnet rotor shown in FIG. 1 in the direction of the arrow x and
- FIG. 3 is a longitudinal sectional view of a permanent magnet rotor according to another embodiment of the invention.
- FIG. 1 shows a longitudinal sectional view of a permanent magnet rotor 1 according to the invention.
- This has a rotor shaft 5, to which a rotor core 2 is attached.
- a rotor core 2 is composed of a plurality of laminations or sheet metal layers.
- the rotor package shown has an inner region 2a which lies between the rotor shaft 5 and receiving pockets 3 of the rotor assembly, and an outer region 2b, which lies between the receiving pockets 3 and the outer periphery 2e of the rotor assembly.
- the rotor package shown has 2 end faces 2c and 2d.
- the permanent magnets 4 in the receiving pockets 3 serve adhesive sheets 6, which are glued to the end faces 2c and 2d of the rotor core.
- the receiving pockets 3 each have two openings 3a and 3b, one of which is provided on the end face 2c of the rotor core 2 and the other on the end face 2d of the rotor core 2. Consequently, a total of two adhesive films for fixing the permanent magnets 4 are used in the receiving pockets 3 in this embodiment, one of these adhesive films on the end face 2c of the rotor assembly and the other adhesive film is provided on the end face 2d of the rotor core.
- the receiving pockets each have only one opening, for example on the end face 2c of the rotor core.
- the respective other end region of the receiving pockets is formed closed in this further embodiment.
- only a single adhesive film is necessary for fixing the permanent magnets in the receiving pockets, which is applied to the end face 2c of the rotor core.
- FIG. 2 shows a view of the permanent magnet rotor shown in FIG. 1 in the direction of the arrow x shown in FIG.
- the outer circumference 2e of the rotor core is not circular, but has a substantially sinusoidal shape.
- the smallest radius of the outer circumference 2e of the rotor stack 2 is designated by the reference numeral 10 in FIG.
- the radius 8 of the adhesive film which has a circular outer circumference, is smaller than the abovementioned smallest radius 10 of the outer circumference 2 e of the stator core 2, but larger than that of the radially outer edges of the stator core 2 Receiving pockets 3 corresponding radius 9.
- the adhesive film can be used independently of the respective present form of the outer periphery of the rotor core. For example, it can be used both with a sinusoidal outer circumference of the rotor stack, as shown in FIG. 2, as well as with a circular outer circumference and with a differently shaped outer circumference of the rotor core.
- Another advantage of the invention is that additional components such as adhesive, a potting compound and / or brackets are not necessary for fixing the permanent magnets in the receiving pockets.
- the functions of these additional components are completely covered by the single adhesive film used, provided that the receiving pockets each have only one opening, or of the two adhesive films used, provided that the receiving pockets each have two openings.
- These adhesive film or adhesive films are easy to apply. It is only a single adhesive film, provided that the recording see each have only one opening, or only two adhesive sheets, if the receiving pockets each have two openings, necessary.
- the adhesive films prevent particles from penetrating into the receiving pockets and thus particles from reaching the permanent magnets as well as ejecting particles from the receiving pockets.
- the permanent magnets are inherently secured against slipping within the respective receiving pocket, since they are held in the center of the respective receiving pocket by the prevailing magnetic forces.
- the permanent magnets could slip inside the respective receiving pocket despite all this. This is prevented in the permanent magnet rotor according to the invention by the use of the above-described adhesive film or adhesive films which absorb the forces occurring during the acceleration.
- the permanent magnet rotor described above is preferably a permanent magnet rotor provided for an actuator of a motor vehicle.
- the actuator serves, for example, as a windscreen wiper motor, as a window motor, as a steering motor or as a motor for an electric seat adjustment.
- FIG. 3 shows a longitudinal section of a permanent magnet rotor according to a further embodiment of the invention.
- This further embodiment differs from the embodiment described above in that the rotor shaft 5 terminates on the end face 2d of the rotor assembly in the axial direction with the end face of the rotor core.
