DESCRIPTION OF EMBODIMENTS

1 shows a schematic plan view of the basic structure of a commutator motor. In a stator 1 are stator poles 2 . 3 , here referred to as permanent magnets with north and south poles N, S, around an armature rotor 4 arranged around. The anchor rotor 4 is on an armature shaft 7 rotatably applied and has a plurality of anchor teeth 5 (Z1 ... 8), one below the other by runner grooves 9 are spaced. Every anchor tooth 5 is with a winding 8th , which is designed as a single tooth winding w1 ... 8 and extending in the rotor grooves provided. The ends of the windings 8th are with slats L of a commutator 6 connected, in particular with Kommutatorhaken. For energizing the commutator 6 are two or more brushes 10 arranged.

In 2 is a schematic, perspective partial view of a commutator 6 a commutator motor according to the invention to illustrate a preferred embodiment shown. This commutator can z. B. in DC version particularly suitable for use in an anti-lock braking device of a motor vehicle, in which an accurate speed detection is required. In this case, for example, an idling speed of the commutator motor is 4500 min ^-1 .

In this preferred embodiment, in 2 only the anchor rotor 4 with the anchor teeth 5 , the commutator 6 and the winding 8th shown. An associated stator 1 with six poles 2 . 3 , preferably permanent magnets N, S is as in 1 already shown and described trained.

The anchor rotor 4 has eight anchor teeth 5 (Z1 ... 8), each with a single tooth winding w1 ... 8. The commutator 6 has twenty-four louvers L (L1 ... 24, see 4 ), of which only a few are shown in more detail here.

The number (twenty-four) of the fins L in this embodiment is a multiple of the pole pair number (three) of the stator poles 2 . 3 and also a multiple of the number of stator poles 2 . 3 (six). Also, the number twenty-four is a multiple of the armature teeth Z1 ... 8 (eight).

The slats L1 ... 8 are at their the anchor teeth 5 facing ends with so-called commutator 13 educated. The commutator hooks 13 serve to accommodate the ends and loops of the single wraps w1 ... 8 and bridges 11 ,

The armature teeth Z1 ... 8 are shown only partially wound to give a better overview of the following explanations.

The bridges 11 serve to connect individual slats L with each other, as described in more detail below. For the bridges 11 also becomes the winding wire 12 used.

In 2 are the commutator hooks 13 not yet bent over and not yet with the winding wires taken up in them 12 and bridges 11 welded.

The laying of the winding wires 12 to the respective commutator hooks 13 takes the form of wire loops 14 , wherein the winding wires 12 and bridges 11 be laid so that they are approximately perpendicular to the respective Kommutatorhaken 13 run. That means the wire loops 14 as a winding wire 12 and as a bridge 11 from the respective commutator hooks 13 radially outward to the rotor grooves 9 are laid, with the wire loops 14 essentially perpendicular to the armature shaft axis 15 run.

With these wire loops 14 do not become wire crossings of the winding wires 12 before and / or under the respective commutator hook 13 educated. The winding wire 12 becomes almost straight at the commutator hook 13 introduced, then in an arc of about 180 ° around the commutator hook 13 guided around and almost straight again from the commutator hook 13 returned in the same direction, from which the winding wire 12 at the commutator hook 13 was introduced. That is, the winding wires 12 and also the bridges 11 are laid without formation of so-called alpha loops.

In this case, both the winding wires 12 as well as the bridges 11 forming winding wires 12 through the runners grooves 9 between the anchor teeth 5 (Z1 ... 8) pulled so that the winding wires 12 and the wires of the bridges 11 approximately perpendicular to the respective commutator hooks 13 run and the wire loops 14 form.

In 2 This is exemplified at the armature tooth Z7, which is shown in the foreground explained.

A bridge end 11e , which of the lamination L3 (in 2 not shown, but see 4 ) as a bridge 11 around different anchor teeth 5 (see also 4 ) around by the runner grooves 9 at the commutator hook 13 the lamella L19 is laid, forms with a winding start 12a the single-tooth winding w7 of the armature tooth Z7 a wire loop 14 from a continuous winding wire 12 , The winding start 12a runs. then as a winding wire 12 back into the runner's groove 9 back, from which the end of the bridge 11e emerges. The single-tooth winding w7 is wound around the armature tooth Z7 (only a few turns are shown for the sake of clarity) and its winding end 12e is with a bridge start 11a as a wire loop 14 in the commutator hook 13 the lamella L20 was added. The bridge start 11a then runs into the runner groove 9 into it (and to more anchor teeth 5 around, like out 4 shows), from which the coil end 12e emerges. The wire loops 14 run approximately perpendicular to the respective Kommutatorhaken 13 , as in particular at the commutator hook 13 the slats L20 and L21 can be seen.

After laying the winding wires 12 and the bridges 11 and the attachment of the same in the Kommutatorhaken 13 becomes the commutator 6 on an armature shaft axis 15 towards the anchor rotor 4 pushed, with no wire damage caused by wire crossings and Kommutatorschieben.

In 3 is the partial view of the commutator motor according to the invention 2 shown from the back.

For the sake of clarity, not all windings are involved 8th and laying the winding wires 12 shown. The winding wires 12 the bridges 11 run around the anchor teeth 5 around and through the runners grooves 9 therethrough. A laying of the bridges 11 at the commutator 6 does not take place, but can of course also be possible in combinations.

4 shows a part of a winding scheme of in 2 and 3 illustrated embodiment for a machine winding method.

Such a mechanical winding method can, for. B. be performed with flyers. In the embodiment shown here, the windings are laid in two strands. Other methods are of course possible.

The winding scheme according to 4 is illustrated in an embodiment for a machine winding. In the upper row, the poles of the stator are only indicated and unwound on the plane of the drawing, as well as the anchor teeth 5 and lamellae L. Among them, the armature teeth Z1 ... 8 and the single-tooth windings w1 ... 8 are only indicated, with the single-tooth windings w1, w4, w5 and w8 are shown in more detail. A sense of winding is indicated by corresponding arrows.

The slats L are indicated in the bottom row and individually numbered, with their respective number being given the L to L1 ... 24. The respective commutator hooks 13 the fins L are not shown here.

In the anchor teeth, the armature teeth Z8 and Z1 are shown in duplicate to better illustrate the relationship of wire laying.

In this embodiment, two brushes 10 provided, which are spaced apart from each other so that in the position shown a brush 10 the lamella L1 and the other brush 10 the lamella L13 contacted.

The single-tooth windings w1 ... 8 and the bridges 11 be in two strands by means of a single winding wire 12 created in one production step. A first strand is shown by solid lines and starts at lamination L1. A second strand is indicated by dotted lines and starts at lamella L13.

It will first be described the partial course of the first strand shown, which with the winding wire 12 in lamella 1 starts. From there, the winding wire 12 to form the single tooth winding w1 in the 4 wrapped clockwise around tooth Z1. The end of the single tooth winding w1 then goes to blade L2, from where the winding wire 12 as a bridge 11 back into the runner's groove 9 (please refer 2 and 3 ) runs back between armature tooth Z1 and Z2. The bridge 11 is then only partially around the armature tooth Z1 counterclockwise around by the rotor groove 9 between armature teeth Z1 and Z8, runs only partially clockwise about armature tooth Z8 (on the right side of the 4 continued) through the runner groove 9 between this and armature tooth Z7 counterclockwise in part and is then through the rotor groove 9 between armature tooth Z7 and Z6 pulled to the blade L18. The course of the bridge 11 similarly goes around the armature teeth Z6, Z5 and Z4 to the fin L10. Thus, in each case three blades (here initially L2, L18 and L10 electrically connected, as will be explained in more detail below.

From the lamination L10 the course of the wire is now again as a winding wire 12 the single tooth winding w4 continues around the armature tooth Z4 and ends at the lamination L4, of which the wire as a bridge 11 in the manner described above by the armature teeth Z4, Z3, Z2 to the blade L3 and then on to the blade L19 (not shown) continues.

The shown partial course of the second strand starts with the winding wire 12 in lamella L13, from where he as a single tooth winding w5 in the 4 is wound clockwise around tooth Z5. The end of the single-tooth winding w5 then runs to blade L14, from where the winding wire 12 as a bridge 11 back into the runner's groove 9 (please refer 2 and 3 ) runs back between armature tooth Z5 and Z6. The bridge 11 As explained above for the first strand, the armature teeth Z5, Z4, Z3 are pulled towards the lamination L6 and further to the lamination L22. Thus, in each case three blades (here L14, L6 and L22 electrically connected.

From the slat L22 the course of the wire is now again as a winding wire 12 the single-tooth winding w8 continues around the armature tooth Z8 and ends at the lamination L23, of which the wire as a bridge 11 is continued in the manner described above to the slat L15.

The bridges 11 become uninterrupted by the runners grooves 9 drawn.
