Definitions
- the invention relates to a rotating electrical machine and a method for its production in accordance with the preamble of claims 1 and 6.
- the invention has for its object to provide a rotating electrical machine with a compact structure, and a method are shown with which such a rotating electrical machine can be manufactured.
- both the rotor and the stator are each wound from a band which is divided into segments which are provided with specially designed slots.
- the connection points of the segments are minimized so that the band cannot be interrupted during the further manufacturing process.
- the inner and outer radius of curvature of each segment is matched to the inner and outer radius of curvature of the stator or rotor.
- Fig. 12 shows the rotation of the rotor core for aligning the webs between the slots.
- two adjacent slots 52 are partially closed to the outside by the cross piece of a web 53 which is oriented perpendicular to the longitudinal axes of the slots 52.
- the dimensions and arrangements of the slots 52 and the dimensions of the segments 51 are selected such that the dividing line 54 between two segments 51 is either centered through a slot 52 as shown in FIG. 3 or as in the variant of a band 5 shown in FIG. 2 is guided by a web 53.
- the end of a dividing line 54 lying within the band 5 opens into a round recess 55 which serves to concentrate and reduce the mechanical deformation when the stator 3 is wound.
- Fig. 4 shows a flat band-shaped component 10 made of a thin metallic material which is designed as an electrical sheet.
- the component 10 is as wide as two strips 5 placed against one another according to FIG. 3. Two such strips 5 are cut out of this component 10 for winding the stator 3 in accordance with the pattern shown here.
- the component 10 can also be somewhat narrower than the pattern, such that, for example, the outward curves 51 R of the segments 51 are omitted.
- the wound stator 3 then has partially flattened areas on the outer surface (not shown here) on, but this has no major disadvantages. The reason for choosing this pattern is to minimize the material.
- the band 5 shows the winding of the stator 3.
- the band 5 is wound on a mandrel 16 in such a way that its segments 51 with their smaller radius of curvature are positioned perpendicular to the longitudinal axis of the dome 16.
- the outer diameter of the dome 16 is matched to the desired inner diameter of the stator 3.
- the tape 5 is wound up until the stator 3 has the desired dimensions. Then the tape 5 is cut. In order to prevent the tape 5 from unwinding independently of the mandrel 16, it is permanently attached. The wound layers of the tape 5 are then pressed. The stator 3 is thus completed.
- FIGS. 7 and 8 each show the partial area of a band 6 which is used for winding the rotor 2.
- the band 6 is divided into segments 61.
- Each segment 61 is adapted to the inner and outer radius of curvature of the rotor 2.
- the segments 61 are all the same size.
- each segment 61 is provided with two or three slots 62, depending on whether the dividing line is guided centrally between two slots 62 or through a slot 62.
- the slots 62 are oval, all the same size, closed to the outside and separated from one another by webs 63. If the segments 61 are designed in such a way that the dividing line between two segments 61 is guided through the middle, then, as shown in FIG. 8, the inner end of the dividing lines 64 opens into a circular recess 66, which reduces the mechanical deformation during winding of the rotor 2 is used.
- FIG. 9 shows a flat component 12 made of a thin metallic material which is designed as an electrical sheet.
- the component 12 in the exemplary embodiment shown here is approximately narrower than two bands 6 according to FIG. 7, which are set against one another here. According to the pattern shown here, two tapes 6 for winding the rotor 2 can be simultaneously pulled out of the component 12. be cut. The reason for choosing this pattern, like the pattern shown in Figure 4, is to minimize the material.
- the band 6 is wound on a mandrel 17 in such a way that its segments 61 with their smaller radius of curvature are positioned perpendicular to the longitudinal axis of the dome 17.
- the outside diameter of the mandrel 17 is matched to the desired inside diameter of the rotor 2.
- the tape 6 is wound up until the rotor 2 has the desired dimensions. Then the tape 6 is cut. In order to prevent the tape 6 from unwinding independently of the mandrel 17, it is permanently attached. The wound layers of the tape 6 are then pressed.
- a slot 62 of the previous layer and also a slot 62 of the subsequent layer of the tape 6 are positioned congruently when winding the tape 6 in front of and behind each slot 62 of a layer.
- Continuous cavities 2H are thus formed in the rotor 2, as shown in FIG. 1, whose longitudinal axes run parallel to the longitudinal axis of the rotor 2 and whose cross sections correspond to the cross sections of the slots 62.
- the band 6 is also designed such that when winding up before and after each dividing line 64 between two segments 51, no dividing line 64 is arranged.
- 10 shows the dividing line 64 of a first wound layer, which is shown interrupted, and a first dividing line 64 of a second wound layer. The dividing line 64 of the second layer is shifted so far from the dividing line 64 of the first layer that the distance between the two corresponds to the distance between the centers of two slots 62.
- FIG. 11 shows a partial area from the outer surface of the rotor 2.
- the positions of the dividing lines 64 in four layers 6A, 6B, 6C, 6D of the band 6 are marked with X. It can also be seen here that no dividing line (not shown here) is positioned immediately in front of or behind another dividing line. In order to achieve this, here too
- nseg which relate to the number of slots 62 and the number of segments 61 are the same here as explained in the description of FIG. 5.
- the desired inclination of the longitudinal axes of the webs 63 can also be achieved by slightly increasing each web 63, namely by ⁇ r.
- ⁇ r 360 ° / Nr and Nr is the number of slots 62 of the rotor 2.

Abstract
L'invention concerne une machine électrique rotative (1) comportant un rotor (2) logé à l'intérieur et un stator (3) disposé à l'extérieur. Le rotor et le stator sont respectivement bobinés à partir d'une bande (5, 6). Chaque bande (5, 6) est divisée en segments (51, 61) adaptés aux courbures intérieure et extérieure du rotor (2) et du stator (3) respectivement. Chaque segment (51, 61) comporte un nombre défini de fentes (52, 62) disposées exactement les unes derrière les autres lors du bobinage du rotor (2) ou du stator (3), de manière à créer des espaces creux (2H, 3H) destinés à recevoir des enroulements électriques.
