Definitions
- a stand and an electrical machine according to the preamble of claim 1 are already known from Japanese laid-open specification 9-103052. To make this
- the stand according to the invention with the features of the main claim has the advantage that, by specifying the weld depth as a function of the effective yoke height and a tolerance value for the weld depth, a regulation is specified by which the various influencing parameters on the stand of an electrical machine can be controlled safely and reliably are so that on the one hand a tearing open of the Weld seam at the joint after welding is safely avoided and, on the other hand, for example, the electromagnetic properties of the stator iron at the joint are not adversely affected.
- a regulation for determining the weld depth T s according to which the weld depth T s by the following function depending on the yoke height H yoke and a tolerance value
- T s 0.5mm * (H mm -1) ⁇ ⁇ T S ,
- the weld seam is of sufficient strength to absorb the tensile forces in the weld seam at a certain yoke height, on the other hand, the weld seam is not too deep, so that it does not negatively influence the magnetic properties at the weld site due to structural changes in the yoke. These influences include, for example, the level of undesirable eddy current losses that arise.
- the size ⁇ T S has an amount of 1 mm, there is a secure welded connection for the resulting minimum value and, on the other hand, the weld seam is not too deep as far as the maximum value is concerned.
- the weld seam quality can be reproduced particularly reliably.
- the welding point is particularly far away from the yoke and, on the other hand, a relatively large amount of heat can be emitted from this external tooth during the welding process. Some of the heat therefore does not reach the yoke.
- the yoke's electromagnetic properties are less affected. If the weld seam is arranged on a radial inside of the yoke, so that the joint is arranged on a tooth head, then the oscillation of these half teeth is reliably avoided.
- the execution of the weld means that the method for producing the
- stator core consists of a material that has no more than 0.1% carbon content (mass content).
- the carbon content influences the brittleness of the weld seam and thus the durability, for example under vibration.
- FIG. 1 shows a stand according to a first embodiment
- Figure 2 is an end view of two fillings of welds on the joined
- FIG. 3 is a diagram showing the function for the weld depth T s for different parameters
- FIG. 4 and FIG. 5 a front view of two further exemplary embodiments of weld seams on the assembled stator core
- Figure 6 is an illustration for determining the yoke height with a special design of the yoke. description
- the stator 10 has an annular stator core 13 made of a stator core segment 14.
- the stator core 13 consists of a stator core segment 14, which in turn is made from a large number of individual stator lamellae 15.
- the stator core 13, like the prior art, has radially inwardly directed slots 18 into which a stator winding 17 is inserted.
- This stand 10 is manufactured as described below. Individual, generally strip-shaped stator lamellae 15 are produced, which can extend in the shape of an arc or straight.
- the individual stator lamellae 15 are packaged in such a way that a side is formed which is continuously provided with slots 18, into which the stator winding 17 is later inserted.
- stator winding 17 After inserting the stator winding 17, an assembly of the stator core 13 and the stator winding 17 is formed, which is then bent round so that a cylindrical cavity is formed in which the slots 18 end. To fix this state, it is provided that at least two ends of the stator core 13, which are opposite one another after the round bending, are fixed by means of a weld seam 20. Otherwise, the stand 10 would gap at the joint. An installation in a cylindrical bore of a housing could hardly be accomplished.
- the joint 22 is shown.
- One end 23 of at least one stator core segment 14 can be seen on either side of the joint 22. Both ends 23 are designed such that one partial tooth 24 abuts another partial tooth 24. Both partial teeth 24 act together as a whole tooth.
- the cross-section of the weld seam 20 can be seen at the joint 22.
- the weld seam 20 has a weld depth T s in the radial direction, ie in the direction along the joint or the surface in which the partial teeth 24 rest.
- a partial tooth 25 has a yoke height H J ⁇ h .
- T ⁇ 0.5mm * (H, 7mm -1) ⁇ ⁇ T
- the weld depth T s is therefore dependent on the yoke height H iodine] and the tolerance value ⁇ T S.
- the function for determining the weld depth T s therefore consists of a basic function f B
- H yoke and ⁇ T S must be given in millimeters (mm), (H yoke / mm -1) is dimensionless.
- ⁇ T S corresponds to the quantity ⁇ T S1 , which has an amount of 1.0 mm.
- ⁇ T S2 which has an amount of 0.5 mm.
- FIG. 3 shows the function for T s for the different parameters, ie as a function of the yoke height and the tolerance value ⁇ T S.
- the function of the minimum weld depth T. which is dependent on the yoke height H yoke is shown in FIG. The function can be described by
- the weld seam 20 is formed on a tooth formed on the outside 30 of the yoke from two partial teeth 31, see FIG. 4.
- the weld seam 20 on a radial inner side of at least one end 23 of the stator core segment 14 is arranged, see also FIG. 2.
- a weld seam 20 is arranged on an axial side of the stator 10 or the stator core 13. This weld seam 20 on the axial end face can additionally be attached, cf. Figure 5.
- the effective yoke height H yoke is not synonymous with the yoke height as described above.
- the projected yoke height H yoke is to be determined as the effective yoke height H yoke , which serves as the basis for determining the required weld depth T s according to the equation specified at the beginning. This is done from the actual Yoke height between two teeth 25 subtracted the radial extension of the groove 35, cf. Figure 6. In this case, the value of the projected yoke height H yoke is to be used for the factor H yoke .
- stator core 13 or the stator lamellae 15 consist of an iron-containing material which has no more than 0.1% carbon content (mass fraction). It is provided that the stator core 13 is equipped with the stator winding 17 before the welding process at the joint 22 and bent together.
- the weld seam 20 has a tensile strength of between 10 kN and 44 kN in the circumferential direction of the yoke 26. Furthermore, the weld seam should have a tensile strength between 20 kN and 36 kN at a depth between 0.9 mm and 2.2 mm. At depths between 1.1 mm and 1.8 mm, the tensile strength should be between 22 kN and 32 kN.
