Definitions

  • EP 730 334 AI shows a stand for an electrical external pole machine, in which the stand is assembled from two parts. Due to this two-part shape of the stand, the individual parts cannot be wound, but must be assembled with pre-made spools. The advantages of this type of assembling the
  • stator essentially only results for two poles. Although an exemplary embodiment for several poles is also specified, these are only secondary poles and the desired advantage of better filling of the slots is no longer achieved with more than two poles.
  • JP 2000209794 AI or US Pat. No. 5,859,486 show a stator which consists of as many segments as there are pole teeth. This creates a large number of parts that have to be assembled in a complex manner.
  • US Pat. No. 5,552,651 shows a rotor which is made up of two parts. However, the rotor has no windings around the pole teeth.
  • stators or rotors are known in which the teeth are set individually. Every single pole tooth has to be fastened, which makes a complex assembly process necessary. These stators have reduced stability. Furthermore, each individual coil must be contacted, which results in a large number of contact points and complex operations with, for example, lead frames.
  • the component according to the invention for an electrical machine with the characterizing features of claim 1 5 has the advantage that in a simple manner and
  • a component for an electrical machine is formed in which an optimal filling of the slots with windings or coil packs is achieved. In this way, a smaller size of an electrical machine can be achieved.
  • Carrier bodies are formed because there is a large distance between the pole teeth of a single carrier body.
  • Fig. 1, 2) or complete (Fig. 3) creating the winding
  • the carrier body advantageously consists of 0 sheet laminates because eddy currents are minimized.
  • the carrier body advantageously consists of a plastic / magnetic material because it is easy to manufacture. 2/058210
  • Such a component can advantageously form a stator or a rotor.
  • Figure la shows a first embodiment of the component according to the invention in the unassembled state
  • Figure lb in the partially assembled state

  • FIG. 3a shows a further exemplary embodiment of the component according to the invention in the non-assembled state
  • FIG. 3b in the assembled state.
  • FIG. 1 a shows a component 1 according to the invention in the non-assembled state.
  • the component 1 can be excited magnetically, for example by an electrical coil or a magnet, and is used for an electrical machine, e.g. a motor or generator is used.
  • the component 1 consists at least of a first carrier body 3 and a second carrier body 5. Both carrier bodies 3, 5 are, for example, identical and are assembled in the axial direction 7 and together attached.
  • the axial direction 7 forms, for example, a central axis 7 of the component 1.
  • the carrier body 3, 5 has, for example, an outer ring 9, on which, for example, at least one pole tooth 11 is formed.
  • the pole tooth 11 is made in one piece with the outer ring 9, for example.
  • the pole tooth 11 can, however, also be attached to the ring 9, for example by being pushed on or molded on.
  • the pole tooth 11 projects beyond the ring 9 in an axial direction 7.
  • the pole tooth 11 For fastening the carrier bodies 3, 5 to one another, the pole tooth 11 has, for example, an insertion element 13 on the outer circumference, which is inserted into a corresponding recess 15 on the ring 9 of the other carrier body 5, 3. This prevents the carrier bodies 3, 5 from rotating relative to one another in the radial direction.
  • the carrier bodies 3 and 5 can also be fastened to one another if, for example, a press fit occurs between the insertion element 13 and the recess 15.
  • the carrier bodies 3, 5 can also be fastened to one another in other ways.
  • the component 1 then has six pole teeth 11.
  • the carrier body 3, 5 consists, for example, of sheet metal laminates or of a solid material.
  • the carrier body 3, 5 can also consist of a mixture of plastic and a magnetic material, in particular a soft magnetic material, which is injected, for example.
  • Magnetic material is understood to mean magnetizable material and / or magnetized material.
  • the material can be hard and / or soft magnetic.
  • One of the carrier bodies 3, 5 can consist of sheet metal laminate and the other consists of a mixture of plastic and a magnetic material,
  • FIG. 1b shows a component 1 in which the carrier bodies 3, 5 are partially pushed into one another.
  • the carrier bodies 3, 5 are joined together such that the pole teeth 11 of one carrier body 3 extend between the pole teeth 11 of the other carrier body 5.
  • Figure lc shows a component 1 in the assembled state.
  • the pole teeth 11 are each formed by another carrier body 3, 5, for example.
  • the rings 9 of the carrier bodies 3, 5 as well as the insertion elements 13 and the depressions 15 of the carrier bodies 3, 5 lie directly against one another, so that they form an outer ring 9, so to speak.
  • Such a component 1 is used for a stator of an internal rotor motor.
  • FIG. 1 a Even in the non-assembled state, as shown in FIG. 1 a, a prefabricated coil package 17 is arranged around each pole tooth 11 or a winding 17 has been wound.
  • the coils 17 are deliberately not shown in FIGS. 1 a and 1 b to show how the carrier bodies 3, 5 are constructed and are joined to one another. Due to the large distance between the pole teeth 11 of the individual carrier bodies 3, 5 in the unassembled state, there is a lot of space for a winding tool, in particular a needle, of a winding machine during the winding process, so that the winding process is greatly simplified.
  • the space is between the pole teeth 11 are optimally filled because the coils 17 can be pushed together very closely in the axial direction 7. During the winding process, for example, there must be enough space for the winding needle, ie a distance from the next spool 17, since the winding needle would otherwise be pinched.
  • FIG. 2a shows a further exemplary embodiment of a component 1 according to the invention.
  • the component 1 likewise consists, for example, of two carrier bodies 3, 5 which have pole teeth 11 which are arranged on an inner ring 9 and extend away from the ring 9 in the radial and axial direction.
  • the carrier bodies 3, 5 are assembled in a similar manner to that described in FIGS. 1 a, 1 b and 1 c.
  • facing the ring 9 on the pole teeth 11, for example, ring segment-shaped insertion elements 13 are formed which form depressions 15 between them for inserting the insertion elements 13 of the other carrier body 3, 5.
  • coils 17 are already present around the pole teeth 11, which are, for example, dovetail-shaped, but are not shown here for reasons of clarity.
  • Figure 2b shows the component 1 in a partially assembled state and Figure 2c in the assembled state.
  • the rings 9 of the carrier bodies 3, 5 form a ring 9 X which has an opening 19 into which, for example, a rotor shaft is inserted and fastened.
  • Such a component 1 is, for example, a stator for an external rotor motor or a rotor for an internal rotor motor.
  • the carrier bodies 3, 5 are designed in accordance with the descriptions for FIGS. 2a, 2b, 2c.
  • one carrier body 5 only has intermediate poles 11 ⁇ which are designed differently than the pole teeth 11 of the other carrier body 3, ie the intermediate poles 11 ⁇ have a pole head 21 which is narrower in the circumferential direction than that of the pole teeth 11.
  • the so-called intermediate poles 11 * are used for magnetic flux guidance.
  • the winding can be applied completely to carrier body 3 without interruption.
  • the rings facing ⁇ 9 to the intermediate poles 11 and pole teeth 11 which serve for assembling insertion elements 13 and recesses 15 are provided.
