Definitions
- the invention relates to an electrical machine with a stator with a winding system and a rotor.
- Toothed coil windings ie concentrated windings around a mechanical pole, cause a comparatively significantly higher spectrum of air gap fields, which cannot be reduced by the above-mentioned methods due to the properties of the toothed coil technology. In particular when using toothed coil windings in asynchronous motors, this leads to malfunctions in the operating behavior.
- the invention is therefore based on the object of creating an electrical machine in which only a specifiable spectrum of air gap fields induces a voltage in rotor conductors.
- Toothed coil windings the number of basic pole pairs of the stator is equal to the number of useful poles p N , have low winding factors for the number of useful poles and excessive winding factors for unused number of pole pairs and are therefore not to be preferred. Therefore, a tooth coil arrangement is proposed gene, which has a comparatively high winding factor for the number of useful poles p N and also filters out troublesome pole pair numbers.
- the structure of the stator advantageously has a fractional tooth pitch.
- different, preferably two, tooth pitch widths alternate, only the teeth with the larger tooth pitch width being provided with at least one tooth coil each.
- a fractional tooth division of the stator permits a reduced parasitic spectrum, so that the air gap fields now only have a certain predeterminable proportion of the respective entire spectrum.
- the rotor and / or the stator are additionally beveled, i.e. the grooves do not run exactly axially but have a predeterminable helix angle.
- the value of the helix angle depends on the number of poles to be damped.
- the conductors of the rotor are switched into conductor loops according to the invention in such a way that the number of useful poles p N represents the number of basic pole pairs GR of the conductor loops of the rotor.
- the number of slots of the slots covered with conductor loops is an integral multiple of twice the number of useful pole pairs.
- additional grooves which are not occupied by conductor loops are advantageously provided in the plate of the rotor
- the conductor loops of the rotor with at least two separate branches preferably consist of aluminum rods, copper rods, copper windings or stranded wires.
- FIG. 7 electrical machine with conventional winding
- FIG 8 electrical machine with toothed coil winding
- FIG. 1 shows a schematic jacket development representation of a rotor 7, not shown in detail, with three short-circuit windings 8, 9, 10, which are electrically separated from one another, with twelve slots and the number of basic pole pairs Several short-circuit windings which are galvanically isolated from one another are also possible in or on a rotor 7. These short-circuit windings according to the invention are also referred to as conductor cages.
- the second winding of the rotor 7 is electrically out of phase by 180 °.
- phase shift ⁇ P - P m-stranded winding systems of a rotor 7 The following generally applies to the phase shift ⁇ P - P m-stranded winding systems of a rotor 7 according to the invention:
- a number of strands with m> 3 is possible.
- the manufacturing cost of a winding system increases with increasing number of strands m.
- the described invention is preferably suitable for asynchronous machines with toothed coil winding, but it is also suitable for synchronous machines with fractional tooth pitch with an additional induction rotor in order to dampen or eliminate disruptive pole pair numbers.
- Toothed coils are understood to be concentrated coils, each of which comprises a mechanical pole or tooth 5 and thus the forward and return conductors of the toothed coil 6 are arranged in immediately adjacent grooves of the tooth 5.
- the toothed coils 6 can preferably be provided prefabricated.
- a fractional tooth pitch is understood to mean that teeth 4, 5 with different tooth pitch widths alternate in the circumferential direction of the stator 3 of a three-phase machine, only the teeth 5 with the larger tooth pitch width ⁇ zp preferably being provided with tooth coils 6.
- the tooth part advantageously corresponds to tion width ⁇ z of the wound tooth 5, o, 66 to 1.0 times the pole pitch of a rotor, not shown.
- FIG. 7 shows an electrical synchronous machine 13 with a stator 3, which has a classic winding system, i.e. there are longed windings.
- a stator bore e.g. a rotor 7 according to FIG 4 is used.
- the electrical machine according to the invention is particularly suitable for production machines, for example machine tools, as well as for driving electric vehicles.
