Definitions

  • the invention relates to a method for producing a brush-commutated DC motor according to the preamble of claim 1 and a brush-commutated DC motor.
  • a brush-commutated DC motor includes a stator having a plurality of exciting poles and a rotor rotatable about an axis of rotation to the stator.
  • the rotor has a plurality of pole teeth and grooves disposed between the pole teeth separating the pole teeth along a circumferential direction about the rotation axis.
  • Coil windings are arranged on the pole teeth, which are energized in the operation of the brush-commutated DC motor via a commutator arranged on the rotor and in this way bring about an electromotive force on the rotor in interaction with the exciter poles of the stator.
  • the commutator comprises a plurality of fins, to which the coil windings of the rotor are connected via connecting arms.
  • a first winding circulation and a second winding circulation in each of which a coil winding is arranged on each pole tooth, are conventionally carried out in an identical manner. Because the coil windings are wound on the pole teeth in different winding cycles, however, coil windings which differ in their position are produced at each pole tooth. Thus, a subsequent coil winding of a subsequent winding circulation is wound on a coil winding from a previous winding circulation, with the result that the wire length of the later wound, outer coil winding is greater and thus result in operation parallel branches of coil windings, resulting in their electrical Resistance - due to the different wire length - can distinguish. This can result in asymmetries in the commutation current.
  • first coil winding wound around the pole tooth in a first winding direction and a second winding direction wound in a first winding direction opposite the second winding direction wound around the pole tooth, second coil winding are arranged on each pole tooth
  • the first coil windings are wound.
  • At least one first coil winding in the first winding direction and a second coil winding in the opposite, second winding direction are attached to each pole tooth. This takes place in different winding cycles, wherein a coil winding is attached to each pole tooth per winding revolution.
  • first coil windings are arranged in a first winding circulation at a first part of the pole teeth and second coil windings are arranged at a second part of the pole teeth, while second coil windings are attached to the first part of the pole teeth and first coil windings are attached to the second part of the pole teeth in a subsequent second winding circulation become.
  • This has the effect that, for the first part of the pole teeth, the first coil windings are arranged inside the second coil windings because the second coil windings are wound on the first coil windings, whereas for the second part of the pole teeth the second coil windings are arranged inside the first coil windings, because the first coil windings are wound on the second coil windings.
  • the difference Wire lengths between the first coil windings and the second coil windings not uniform, but in different ways.
  • the wire lengths of the second coil windings wound on the first coil windings are longer than the wire lengths of the first coil windings, while for the second part of the pole teeth, the wire lengths of the first coil windings are larger than the wire lengths of the second coil windings , In this way, asymmetries in the resulting electrical branches during operation of the DC motor can at least be reduced so that an at least approximately uniform height results in the commutation current, because parallel branches can have an approximately symmetrical resistance distribution.
  • first coil windings are wound on one half of the pole teeth per winding revolution, and second coil windings are wound on the other half of the pole teeth.
  • the first part may include N / 2 + 1 of the pole teeth and the second part N / 2-1 of the pole teeth, where N equals the number of pole teeth of the rotor and is an odd integer number.
  • N / 2 + 1 first coil windings and N / 2-1 second coil windings are wound on the respectively assigned pole teeth in the first winding circulation.
  • the first coil winding is connected via a first connecting arm with a first blade and a second connecting arm with a second blade, wherein the first connecting arm and / or the second connecting arm of the first coil winding around at least one other pole tooth around to the respectively associated Slats are laid.
  • This is based on the idea not to lay a connecting arm of a coil winding directly from the wound on a pole tooth coil winding to the associated blade, but around one or more Pohlzähne around.
  • the laying of the connecting arm can be advantageous to the blade around one or more pole teeth around because crossings of connecting arms of different coil windings can be avoided in this way.
  • the laying of the connecting arms can thus be done in a cheaper, space-saving manner.
  • the first winding arm of the first coil winding by exactly one of the associated pole tooth in the circumferential direction adjacent pole tooth around and the second winding arm of the first coil winding laid by exactly one of the associated pole tooth opposite to the circumferential direction adjacent pole tooth around.
  • the first connecting arm of the first coil winding may, for example, by a first groove adjacent to the associated pole tooth in the circumferential direction around the pole tooth adjacent to the associated pole tooth in the circumferential direction and through a second groove different from the first groove toward the associated blade extend.
  • the second connecting arm of the first coil winding then extends through a third groove adjoining the associated pole tooth against the circumferential direction, around the pole tooth adjacent to the associated pole tooth and adjacent to the circumferential direction and through a fourth groove different from the third slot the lamella associated with it.
  • the connecting arms of the first coil winding on a pole tooth thus extend in different directions away from the coil winding, viewed along the circumferential direction, and are laid around the pole teeth on the left and right of the pole tooth on which the coil winding is arranged.
  • the connecting arms of the first coil winding are thus not guided by the pole tooth directly to the associated slats, but laid around the adjacent pole teeth around and only then led to the slats and connected to this.
  • the connecting arms of the first coil winding are thus routed around other pole teeth
  • the connecting arms of the second coil winding can be connected to adjacent lamellae, which are arranged radially inside the second coil winding and thus are at least approximately at the same circumferential position as the coil winding.
  • the connecting arms of the second coil winding are in this case advantageously connected to adjacent lamellae and intersect. While the connecting arms of the second coil winding are connected to adjacent lamellae, the connecting arms of the first coil winding are connected to lamellae, which are offset in the circumferential direction to these adjacent lamellae.
  • the first connecting arm is connected to a first lamella, which is offset in the circumferential direction to the adjacent lamellae
  • the second connecting arm of the second coil winding is connected to a second lamella, which is offset against the circumferential direction to the adjacent lamellae.
  • one or more other slats may be arranged, so that both the first slat and the second slat are spaced apart from the adjacent slats in the circumferential direction by one or more slats.
  • the number of pole teeth corresponds, in a specific embodiment, an odd, integer number, while the number of lamellae corresponds to twice the number of pole teeth.
  • six exciter poles can be arranged on the stator.
  • the number of pole teeth may be, for example, 7, 9 or 11, while the number of lamellae is 14, 18 or 22, respectively.
  • the coil windings are preferably designed as so-called concentrated windings, also referred to as single-number windings. This is to be understood that the coil windings are each wound around exactly one pole tooth and thus are made by wrapping a Polniers by means of a wire.
  • the coil windings may, for example, each have one, two or three or more turns and be made of a suitable winding wire.
  • short-circuiting bridges which serve to short-circuit individual lamellae of the commutator in order in this way to reduce the number of required pairs of brushes ideally to one. If, for example, the number of excitation poles is six, then each short-circuiting bridge advantageously short-circuits three lamellae so that the three lamellae are in the same potential when one of the lamellae comes into contact with a brush.
  • the shorting bridges extend, for example, for shorting two lamellae each with at least one portion around at least one pole tooth, each passing from a lamination through a groove between two pole teeth, around at least one pole tooth and through another groove through to another lamination extend.
  • this makes it possible to reduce the installation space because no additional installation space has to be provided for the short-circuiting bridges.
  • the short-circuiting bridges can be laid in a simple manner through the grooves around one or more pole teeth in order to connect lamellae with each other in a short-circuiting manner.
  • connecting arm or a shorting bridge are placed around at least one pole tooth
  • the connecting arm or a shorting bridge at least partially surrounds a pole tooth.
  • the connecting arm or the shorting bridge surrounding the pole or the teeth thereby circumferentially but not completely, but are for example, starting from a front of the rotor, on which the blades of the commutator are arranged, inserted into a groove extending on a rear side of the rotor along one or more Polzähne and are guided through another groove back to the front of the rotor, to be connected at this front with an associated lamella.
  • the coil windings and the shorting bridges are advantageously made of a continuous wire and can thus be mounted in a continuous operation by continuous winding and laying on the pole teeth of the rotor. This results in a simple production, which can be automated in a favorable manner by using suitable winding machines. In particular, no separate operation is required after attaching the coil windings to install suitable shorting bars. In addition, eliminates additional components that are commonly required for shorting bars, so that the number of components required in total can be reduced.
  • the result is preferably an arrangement on the rotor in which a section of a short-circuiting bridge is arranged in each case between two coil windings.
  • a coil winding is attached to a pole tooth and connected to a respective connecting arm with a blade, in which case one section of a shorting bridge is laid from one connection arm to another one, and another coil winding connects to this section of the shorting bridge.
  • the continuous wire forms a first coil winding, then a section of a shorting bridge, then a second coil winding and then another section of a shorting bridge, which in turn is followed by a first coil winding.
