Definitions
- stator packs which are composed of a large number of stator laminations. These stator fins are held together by means of a pole housing.
- the pole housing is shrunk onto the stator fins by a shrinking process, as a result of which the fins are held and fixed. Due to the different materials, different thermal expansions are obtained for the housing and the stator fins during engine operation. This can lead to the indefiniteness of the stator fixation, plasticization of the housing material and damage to the stator. Furthermore, reworking of the housing or the stator laminations is often necessary in order to achieve the necessary tolerances for the components.
- the stator arrangement according to the invention with the features of patent claim 1 has the advantage that it can be manufactured particularly easily and inexpensively, in particular by deep drawing or extrusion.
- a housing of the stator arrangement has at least one bead which runs in the axial direction and faces inward. At the in.
- the stator formed on the housing allows the stator to be attached to the housing. A secure connection between the housing and the stator can be ensured by means of the resilient bead.
- the stator particularly preferably further comprises at least one bead which runs in the axial direction, faces inwards or outwards.
- the beads on the housing and the beads on the stator are preferably designed such that the housing is connected to the stator at a plurality of connection points in the assembled state. It is between the individual
- connection points each formed a gap in the U direction.
- the housing and the stator are only connected to one another in a spring-loaded or clamping manner, so that very low deformation forces act on the Stator or the housing must be exercised. This enables compliance with very narrow positioning tolerances between the stator and ball bearing seat and thus also the rotor.
- a gap at the lowest point of the beads is particularly preferably present between a bead of the housing and a bead of the stator in the assembled state. This can be achieved particularly easily, for example, by the radii of the beads of the housing and the stator being different.
- a plurality of beads are preferably formed on the housing and on the stator, which are equally spaced from one another in the circumferential direction.
- Four of the six beads are particularly preferably formed because of the measurability of the coaxialities on the housing and on the stator.
- the lengths of the beads on the housing in the axial direction correspond to the length of the Siator in the axial direction. This enables a particularly secure and simple connection between the stator and the housing.
- a bearing for an armature shaft of the electrical machine is preferably integral on the housing educated.
- fastening openings with a stop shoulder for the ball bearing outer ring on the housing for fastening the electrical machine are also preferably formed integrally.
- the stator is preferably made of a large number of stator laminations made of sheet steel and the housing is also made of sheet steel, so that during operation of the electrical machine there are no negative influences due to loosening or high compression at high and low
- Guide surfaces for attaching a second bearing cover are further preferably formed on the housing. This allows, in particular, an integrated into the housing
- Bearing cover for supporting the armature shaft a particularly high coaxiality between the stator and an armature mounted on the housing can be achieved.
- the housing is preferably deep-drawn and the beads are molded into the housing by pressing.
- the stator is preferably provided from a multiplicity of individual sheets which are produced by means of stamping.
- the present invention relates to an electrical machine with a rotor-stator assignment according to the invention and in particular to an electrical motor, such as an asynchronous motor, with the smallest possible air gap between the armature and the stator.

- FIG. 2 shows a schematic sectional view of a housing shown in FIG. 1,
- FIG. 3 shows a schematic plan view of a stator sheet according to the first exemplary embodiment
- FIG. 4 shows a perspective illustration of the stator sheet shown in FIG. 3,
- FIG. 5 shows a schematic, perspective arrangement of a stator, which is composed of a large number of individual stator sheets,
- FIG. 6 shows an enlarged partial sectional view of a connection between the housing and the stator according to the first exemplary embodiment
- FIG. 7 shows a schematic, perspective view of a stator arrangement according to a second exemplary embodiment of the present invention
- FIG. 8 shows a schematic sectional view of the stator arrangement shown in FIG. 7, and FIG. 9 shows a perspective view of a stator arrangement according to a third exemplary embodiment of the present invention.
- a stator arrangement 1 according to a first is described below with reference to FIGS. 1 to 6
- the stator arrangement 1 comprises an essentially cylindrical housing
- Figure 2 shows a sectional view of the housing 2.
- six inwardly directed beads X-X are inwardly directed beads X-X
- the beads 3 are arranged along the circumference of the housing 2 at equal distances from one another.
- the beads 3 have a length L in the axial direction X-X, which corresponds to a length 1 of the stator 4 (cf. FIGS. 1 and 5).
- the stator 4 is made in a known manner
- stator laminations 4a A large number of individual stator laminations 4a are assembled. As can be seen in particular from FIG. 3, six inwardly directed beads 5 are likewise formed on the outer circumference of each stator plate 4a at the same distance along the circumference.
- FIG. 6 now shows the assembled state of the stator laminated core in the housing 2.
- the stator laminations are arranged in the housing 2 such that the beads 5 each correspond to the beads 3 of the housing 2.
- At each bead 3 of the housing there are four connection points A, B, C and D.
- Between the individual connection points A, B, C, D there are gaps in the form of columns S1, S2, S3, S4, S5. More accurate, As shown in FIG. 6, a gap S3 is formed at the lowest point of the bead 5 of the stator 4.
- a gap S3 or S4 is also formed between the connection points A and B or C and D between the housing 2 and the stator 4, the gap S2 or S4 at the transition of the stator from the respective bead 5 to the normal outer circumference of the stator are formed.
- the housing 2 receives the plurality of stator laminations 4a which form the stator, positions the stator and fixes it in such a way that it is fixed in a tensioned manner by means of a clamping action between the housing and the stator laminations.
- the large number of stator laminations results in linear connection points between stator 4 and housing 2.
- the housing 2 is made of sheet steel and the individual stator laminations 4a are also made of sheet steel, so that a change in heat has no influence on the fixation of the stator in the housing 2 in the entire temperature spectrum.
- the beads 3 exert a resilient prestressing force on the stator 4 via the only point-to-point connection between the housing 2 and the individual stator laminations 4a, the prestressing force depending on the shape of the bead, for example by the depth of the bead and / or the radius of the bead, can be influenced. Another possibility for influencing the spring force is by a suitable choice of a thickness of the housing 2.
- the stator lamination packet 4 can be fastened in such a way that, for example, the stator packet is inserted into the housing and the beads 3 are then produced by pressing or preformed beads are pressed into their final shape. Another The stator 4 can be fastened in the housing 2 by pressing the stator laminated core into the interior of the housing 2 against the spring force provided by the beads which have already been introduced.
- the stator arrangement 1 according to the invention is particularly preferably used in electric motors. As shown in FIG. 1, through openings can be formed on a flange 2a of the housing 2 in order to secure the housing 2 to another component, for example by means of screws. Furthermore, a bearing for mounting an armature shaft (not shown) can be introduced in a relatively simple manner on the cylindrical sections 2b and 2c.

- the housing 2 is produced, for example, by deep drawing.
- a second bearing cover can be inserted in the area 2b in a simple manner.
- a small step is formed on the area 2b of the housing 2, so that the area 2b serves as a guide ring for the use of a second bearing with an anchor shaft. This enables the armature shaft to be very well coaxial with the housing and thus also with the stator.
- the second bearing is also designed as a cover, so that the housing of the
- a seal can preferably also be introduced in the area 2b between the housing 2 and the second bearing cover. Seals can be installed radially and axially on the one hand and can be easily mounted on the housing 2. Furthermore, a seal can also be provided between the flange region 2a and a further connection part of the electrical machine (not shown).
- the stator package used in the second exemplary embodiment corresponds to the stator package shown in FIGS. 3 to 5 and, as shown in FIG. 6, is connected to the housing 2, so that reference can be made to the description given above.
