Definitions

  • the invention relates to an electric generator, for instance for a wind turbine.
  • a usual generator has a structure such that it is heavy, for instance as a result of the necessity of applying a transmission, using which the rotation speed of the turbine rotor is modified, in particular increased, to that of the generator rotor.
  • a further drawback of known generators is that their electrical efficiency leaves something to be desired.
  • An important cause of this lies in the fact that due to the structure of known generators there is the necessity of leaving quite a large air gap between the magnet means normally forming part of a rotor on the one hand and the stator poles on the other.
  • the stator poles form part of ferromagnetic cores around which windings of an insulated electrically conducting wire are arranged.
  • a low weight is important to reduce the mechanical load on a support construction, for instance a post, a column or the like.
  • the support construction can hereby be lighter and take a less expensive form.
  • an electric generator comprising: a housing; a stator disposed fixedly relative to this housing and having a number of pole-forming cores of laminated ferromagnetic material ordered in a circle, around which cores are arranged respective windings of insulated, electrically conductive wires, which windings are connected electrically to electrical connections, via which electrical energy can be taken off during operation of the generator; a rotor mounted rotatably relative to the housing and comprising a number of magnets arranged in a circle, wherein during rotation of the rotor the magnets pass over said poles and thus cause respective voltages over said windings; characterized in that the magnets arranged in a circle are supported by a metal, for instance ferromagnetic first ring, for instance via glue connections, which metal ring is supported by a second ring consisting of cured plastic reinforced with fibres, which rings are arranged in a housing; the field in the magnets has a direction corresponding to the axial direction of the rotor
  • the generator can comprise according to an aspect of the invention a rotor provided on two sides with respective circles of magnets, which circles of magnets co-act with two respective stators.
  • the rotors have to have a precise, mutually corresponding structure, particularly in respect of the mutual positioning of the magnets, it is possible to achieve that the rotor is loaded substantially symmetrically to both sides, thus avoiding that the magnets and cores exert a force on each other such that the disc-shaped rotor has a tendency to bulge.
  • the generator preferably has the special feature that the magnet material contains neodymium. This latter embodiment can particularly be developed such that the magnet material is NeFeB.
  • Magnets of the described type have the great advantage of being able to generate a very great field strength, which can greatly enhance the transmission efficiency of the generator.
  • a preferred embodiment has the special feature that the rotor is arranged in a plastic casing.
  • a preferred embodiment of the generator according to the invention has the feature that the stator is arranged in a plastic casing. Due to these described structures a very good protection of the rotor and/or the stator is obtained, including the magnets and the electric stator windings, against weather influences, chemical corrosion and the like.
  • Production of the rotor and/or the stator can take place by making use of casting techniques in combination with vacuum-forming.
  • the generator can have the special feature according to an aspect of the invention that the rotor is mounted on its outer edge relative to the stator, for instance with at least one roller bearing, a slide bearing, an air bearing or a magnetic bearing. A possible tendency towards bulging, as already mentioned above, is hereby also effectively prevented.
  • An important aspect of the invention lies in specific parts being manufactured from plastic, which may optionally be reinforced with fibres. As described, use can for instance be made of epoxy reinforced with glass fibres.
  • the generator can have the special feature that at least one cooling conduit through which heat transport medium can flow extends through each core.
  • the heat transport medium can be for instance a gas such as air or a liquid such as water or thermal oil.
  • Such a cooling conduit can be embodied as a conduit or tube of copper or plastic or be embodied in other appropriate manner.
  • a specific embodiment has the special feature that the cores are supported by a ring consisting substantially of laminated erromagnetic material. This embodiment is particularly important in a configuration in which to each core carrying an electrical winding is added a core not provided with a winding. The two said cores together form a magnetic circuit. The magnetic reluctance of this circuit is reduced by said ferromagnetic ring.
  • Said embodiment with a ring of laminated ferromagnetic material can advantageously be embodied such that the ring consists substantially of wound band material.
  • the blades are mutually separated in per se known manner by layers of paper, plastic, lacquer or the like. This measure is per se common in the construction of generators, motors, transformers and the like.

  • FIG. 1 shows a wind turbine with an electric generator 2 according to the invention to be described in detail hereinbelow.
  • Wind turbine 1 comprises a post 3 which is anchored in the ground.
  • the post supports generator 2; this latter supports a turbine rotor 4 with three aerodynamic turbine blades 5, 6, 7.
  • Turbine rotor 4 has a dome-shaped cap 9 in which a bearing 10 is arranged in the manner shown particularly clearly in figures 2 and 3. Coupled to a support column 11 placed rotatably relative to post 3 is a horizontal shaft 12, which is also shown particularly clearly in figures 2 and 3. A disc 13 consisting of epoxy reinforced with glass-fibre and having ventilation openings 14 is coupled to this shaft.
  • This disc serves as stator disc and bears an iron ring 15 as drawn in figure 4 and figure 5 which carries respective pairs of cores 16,17 of laminated ferromagnetic material, in particular steel.
  • Steel is a material combining a good structural strength with favourable ferromagnetic properties.
  • Respective windings consisting of insulated copper wire are arranged around cores 16. These windings are designated with reference numeral 18.
  • the pairs of cores 16,17 are disposed in the manner shown in figure 5. Cores 16,17 are connected to iron ring 15 by respective glue connections.
  • Stator disc 13,15,16,17,18 is wholly embedded in said epoxy material such that poles 29,30, i.e. the free ends of cores 16,17, can also withstand weather influences and chemical corrosion.
  • Shaft 12 supports turbine rotor 4 via bearing 10.
  • This rotor further comprises a rotatable rotor housing 19 which is rotatably coupled via an edge bearing 20 to the widened outer edge 21 of stator disc 13 while maintaining a precise mutual positioning.
  • an air gap 31 is situated between poles 29,30 and the surfaces of magnets 25 directed toward these poles. It is noted herein that these magnets and the associated ring 24 are also encased with epoxy, whereby the corrosion resistance of the rotor is very good, as already described in the case of the stator.
  • air gap 31 are of essential importance for a favourable transmission efficiency of generator 2.
  • edge bearing 20 fulfils an important function.
  • the air gap can hereby have a fixed value which is very small compared to the prior art.
  • the ventilation holes 24 serve for forced cooling of generator 2.
  • the forced cooling can take place by air.
  • a simple forced cooling can be realized by for instance providing holes 14 on their outer side with simple blades.
  • the forced cooling can take place by making use of the flow- pass water as cooling medium. Water can also be a very suitable cooling medium in the case the generator according to the invention is used on board ships.
  • FIG 3 it will be apparent that turbine rotor 4 is supported by bearings 10 and 20 for rotation relative to the fixedly disposed stator.
  • Figure 4 shows detail IV of figure 2 on enlarged scale.
  • Figure 5 shows an exploded view of the structure according to figures 2 and 3.
  • Figure 6 shows a structure which differs from the structure according to figures 2,3,4 and 5 insofar that the rotor takes a double-sided form.
  • Ring 24 bears two circles of magnets respectively 25,25' which co-act with respectively stator 15,16,17,18,29,30 and a second stator 15', 16', 17', 18', 29' ,30' .
  • the rotor 24,25,25' in double form is disposed strictly symmetrically with equal mutual distances or air gaps relative to poles
  • Rotor 26 is hereby loaded substantially symmetrically by stators 27 and 28.
  • the edge bearing 20, which is shown particularly clearly in figure 5 in the single- sided embodiment, can be omitted without problem.
  • figure 6 could be modified in the sense that the place of stators 27,28 be taken by two rotors of the type shown in figure 5, between which is situated the double-sided stator taking the place of rotor 26.
  • Figure 7 shows the pairs of poles 29,30 with the associated windings and, with hatching, the magnets 25.
  • FIG 8 shows the structure in question.
  • each stator is sub-divided into six identical segments, wherein diagonally opposed segments co-act electrically with each other such that the three pairs of segments have a three-phase structure.
  • poles 29,30 extend in this view in substantially radial direction.
  • Attention is drawn to the fact that the drawn pairs of segments I-IV, II-V, III-VI have respective phase shifts of 120°. This can be seen from the relevant relative positions of magnets 25 relative to poles 29,30 in the drawn position. These phase shifts of 120° correspond with the necessary phase shift in a three- phase configuration.
  • FIG 9 shows a core 16, wherein for the sake of clarity the winding 18 is not drawn.
  • Core 16 comprises an internal cooling conduit 34 with an inlet tube stub 32 and an outlet tube stub 33 (see also figure 4) . It is particularly important that end zones 35,36 of core 16 are effectively cooled by cooling medium flowing through cooling conduit 34. The heat accumulation is greatest in these zones and the most effective cooling is therefore required.
