Definitions
- the invention relates to a brush-commutated DC motor according to the preamble of claim 1 and to a method for producing a brush-commutated DC motor.
- Such a brush-commutated DC motor known for example from DE 10 201 1 082 543 A1, comprises a stator which carries a plurality of excitation poles, and a rotor, which is rotatable about an axis of rotation relative to the stator and has a plurality of pole teeth. At each pole tooth several windings are arranged.
- a commutator arranged on the rotor has a plurality of fins, wherein each winding is connected to one of the fins via a first winding arm and to another of the fins via a second winding arm.
- a plurality of short-circuiting bridges are provided, each electrically connecting two windings to one another and for this purpose being respectively arranged on at least two lamellae of the commutator.
- the multiple windings of the plurality of pole teeth are in this case formed by a plurality of wire loops, each wire turn a winding each pole tooth and the windings connecting shorting wires and is wound from a continuous wire.
- the number of brush pairs should be equal to half the number of (magnetic) field poles. If a DC motor has, for example, six excitation poles on the stator, three brush pairs, that is to say six brushes, are to be provided which are slidingly in contact with the commutator and energize the windings of the rotor in the desired manner.
- the brushes are in this case distributed uniformly around the axis of rotation on the stator and have an alternating electrical polarity, so that, during operation of the DC motor, a brush with a positive polarity, a brush with negative polarity and vice versa follows.
- the brushes with positive polarity and the brushes with negative polarity are here to be electrically connected to each other, which makes a comparatively large brush holder with a complicated structure and circuit complexity required.
- a plurality of shorting bridges are provided, which are arranged on the rotor and electrically short each at least two lamellae of the commutator in order to bring individual lamellae to an equal potential.
- the number of required brush pairs can be reduced, so that despite the use of z.
- six exciter poles only a pair of brushes is required without the performance of the DC motor is impaired.
- each Lamella is repeatedly connected to one or more wires and thus carries at least as many wire connections, as wire loops are available. For example, if three wire loops provided for the arrangement of three windings on each pole tooth, so each blade carries at least three wire connections, which are for example formed in that the continuous wire of each wire circulation is mounted in a hook provided on the lamella.
- each lamella has to carry a plurality of wire connections
- a correspondingly dimensioned connection means such as a hook, must be provided on each blade, which is able to receive a corresponding number of wire connections. This increases the required installation space of the motor, in particular in its axial length, because space must be provided for the connecting devices.
- the wire circuits are each designed as closed revolutions, in which the circulation begins at a lamella and also ends at the same lamina, then at least one lamella must carry even more wire connections than there are wire circuits.
- winding all the wire loops from a continuous wire results in exactly one blade, to which the wire start and the wire end are connected, so that this blade must carry a number of wire connections, which corresponds to the number of wire loops plus one. If each wire loop is wound from a single continuous wire, then multiple sipes carry a number of wire connections equal to the number of rounds plus one.
- Object of the present invention is to provide a brush-commutated DC motor and a method for producing a brush-commutated DC motor, in which the windings and shorting bars can be wound from a continuous wire, without thereby increasing the axial space requirement too much.
- the present invention is based on the idea that at least one of the wire circuits, by means of which the windings are arranged on the pole teeth of the rotor, should not be designed as a closed circuit.
- a first wire end of the continuous wire with a first lamella and a second wire end of the continuous wire with a different from the first lamella, second lamella are connected so that the wire is connected at its beginning and its end to different lamellae and thus no closed Scope forms.
- first winding which is adjacent to the first wire end
- second winding which is adjacent to the second wire end
- the wire circulation is then closed when the in the wire circulation omitted shorting bridge is formed by another wire circulation, so that the first winding and the last winding of the wire circulation are electrically connected to each other via a shorting bridge of another wire circulation.
- each slat carries a number of wire connections corresponding exactly to the number of wire loops. If, for example, three wire loops are provided to form three windings per pole tooth, then the number of wire connections per slat is advantageously three.
- the plurality of windings of each pole tooth are connected to the same louvers.
- the multiple windings of each pole tooth are thus electrically connected in the same way and are energized in the same manner during operation of the DC motor, so that a parallel connection of the windings results at each Pol leopard.
- the windings as a whole can be wound from a thinner wire, which makes it possible to reduce the radial installation space of the motor.
- the number of wire connections per lamella increases by providing several windings per pole tooth. The fact that not every wire circulation is performed closed, but at least it can be ensured that the number of wire connections per slat does not exceed the number of wire loops.
- each wire loop may be wound from a separate wire.
- the wire circuits can be wound, for example, by the multiple flyer winding technology or multiple needle winding technology and can be made simultaneously by the different wire loops emanating from different pole teeth.
- each wire circulation as non-closed circulation in which the wire start and the wire end are mounted on different blades, be executed.
- a short circuit bridge not provided in a wire circuit can here be formed by a corresponding short circuit bridge of another wire circuit. It results when the wire loops emanating from different pole teeth, a maximum number of wire connections per lamella, which corresponds to the number of wire loops.
- all the wire loops can be wound from a single continuous wire, for which purpose, for example, the needle winding technology or the flyer winding technology can be used. It is thus provided only a continuous wire for attaching all windings, wherein at least the last wire circulation is not closed because the wire beginning and the wire end are connected to different slats.
- the shorting bridge not provided in the last wire circulation is hereby electrically replaced by a shorting bridge of another wire circulation, so that the omission of the shorting bridge in the last wire circulation has no influence on the electrical operation of the motor.
- the shorting bridges for shorting two lamellae can be placed in an advantageous embodiment in each case by at least one pole tooth by each extending from a lamella through a groove between two pole teeth, around at least one pole tooth and through another groove through to another lamella.
- This is based on the idea of attaching the short-circuiting bridges to the rotor in such a way that they extend between the slots between the pole teeth and are accordingly laid in the space in which the windings are also arranged on the pole teeth.
- 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.
- each shorting bridge at least partially surrounds a pole tooth.
- the shorting bridges surround the pole teeth or teeth circumferentially but not completely, but are for example, starting from a lamella on a front side of the rotor, on which the lamellae 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 another lamella.
- the shorting bars are not necessarily routed through the slots or around a pole tooth. Rather, the short-circuiting bridges can also be passed under the commutator.
- the number of excitation poles which may be formed by permanent magnets on the stator, for example, may be six, the number of pole teeth may be eight, for example, and a total of twenty-four lamellae may be provided on the commutator, wherein in principle other numbers of excitation poles, Polzähnen and lamellae are conceivable and possible.
- the windings are preferably designed as so-called concentrated windings, also referred to as single-number windings. This is to be understood that the windings each extend only around a pole tooth and thus are made by wrapping a Polniers by means of a wire.
- the windings may, for example, each have one, two or three or more turns and be made of a suitable wire.
- the short-circuiting bridges serve to short individual slats of the commutator in order to reduce the number of required pairs of brushes ideally to 1 in this way.
- each shorting bridge advantageously short three blades, so that the three blades are at a same potential at contact of one of the blades with a brush.
- the short-circuiting bridges respectively short-circuit each other exactly three lamellae, the short-circuiting bridges advantageously extend in each case from a first lamella of the commutator around two pole teeth to a second lamella and from the second lamella around another pole tooth to a third lamella. In this way, the short-circuiting bridges can be laid in a favorable manner with a view to the required space. In addition, the short-circuiting bridges do not influence the operating behavior of the DC motor or at least not appreciably by such a routing.
- the background here is that by laying the current during operation of the DC motor current leading shorting bars around one or more pole teeth around a magnetic flux in the Poltechnik or the Polzähnen is generated, which can have an influence on the performance of the DC motor. This influence can be minimized by special laying of the short-circuiting bridges around the pole teeth, so that appreciable effects in the operating behavior are not noticeable.
- the object is also achieved by a method for producing a brush-commutated DC motor.
- the brush-commutated DC motor in this case comprises a stator, which carries a plurality of excitation poles, a rotatable about an axis of rotation to the stator rotor having a plurality of pole teeth, and a plurality of windings. At each pole tooth several windings are arranged.
- a commutator is provided, which is arranged on the rotor and has a plurality of fins, wherein each winding is connected via a first winding arm with one of the fins and a second winding arm with another of the fins.
- a plurality of shorting bridges each electrically connect two windings to one another and are each arranged on at least two fins of the commutator.
- the multiple windings of the plurality of pole teeth are formed in the process by a plurality of wire loops, each wire loop comprising a winding of each pole tooth and shorting wires connecting the windings and wound from a continuous wire.
- a first wire end of the continuous wire is connected to a first lamination and a second wire end of the continuous wire is connected to a second lamination different from the first lamination.

- the excitation poles M1-M6 point with different poles N, S towards the rotor 11 such that a north pole N is always followed by a south pole S and vice versa.
- the stator 10 has exactly six exciter poles M1 -M6.
- the rotor 1 1 is arranged rotatably about the rotation axis D on the stator 10 and has eight pole teeth Z1-Z8, which point from the rotation axis D to the stator 10 and via grooves N12, N23, N34, N45, N56, N67, N78 , N81 in the circumferential direction about the rotation axis D are separated from each other.
- the rotor 1 1 can be configured, for example in a conventional manner as a laminated core of individual rotor laminations, in which the pole teeth Z1-Z8 are formed.
- the rotor 1 exactly eight pole teeth Z1 Z8.
- Each pole tooth Z1-Z8 carries one or more windings W1-W8, which are each wound around the pole teeth Z1-Z8.
- the windings W1-W8 are each connected to lamellae L1-L24 (see FIG. 2) of a commutator 110, which is fixedly arranged on the rotor 11 and slidingly arranged with brushes B1, B2, which are fixedly arranged on the stator 10, in operative connection is such that via the brushes B1, B2 and the commutator 1 10, the windings W1 -W8 can be energized to generate an electromotive force (EMF).
- EMF electromotive force
- the commutation of the windings W1-W8 is effected via the commutator 110, as is known, for example, from DE 10 201 1 082 543 A1, the content of which is to be included in the present case.
- Fig. 2 shows a schematic view of the brush-commutated DC motor 1, wherein the brushed commutated DC motor 1 is shown in a rolled-up manner for a simplified overview and corresponding to the excitation poles M1 -M6 and the pole teeth Z1-Z8 and the fins L1 -L24 not along a circle but are arranged along a straight line.
- each winding W1-W8 is connected to exactly two fins L1-L24 of the commutator 110 of the rotor 11, wherein
- the winding W8 is connected via winding arms W81, W82 with fins L22, L23.
- Each pole tooth Z1-Z8 in this case carries - as will be explained below - a plurality of windings W1 -W8, which are electrically connected in parallel and connected to the same fins L1 -L24.
- FIGS. 1 and 2 only one winding W1-W8 per pole tooth Z1-Z8 is shown in FIGS. 1 and 2.
- the result is the Winding arms W1 1-W82 indicated by arrows current flow directions.
- the short-circuiting bridges provide K1-K8 for a uniform current distribution to all brushes.
- the short-circuiting bridges K1-K8 are not laid in any manner between the lamellae L1-L24, but each for short-circuiting the associated lamellae L1 -L24 by at least one pole tooth Z1-Z8 placed so that they each starting from a lamination L1-L24 through a groove N12-N81 between two pole teeth Z1-Z8, around at least one pole tooth Z1-Z8, and through another groove N12-N81 through to another lamination L1-L24 and in this way short-circuit the lamellae L1-L24.
- FIG. 4 A concrete example of such a displacement of the shorting bridges K1 -K8 is illustrated in FIG. 4 on the basis of the shorting bridges K1, K2 emerging from the winding W1.
- the winding W1 is wound around the pole tooth Z1 and connected to a winding arm W1 1 with the lamination L1 and with the other winding arm W12 with the lamination L2.
- the shorting bridge K1 extends around the pole tooth Z2 and extends to the lamination L9, from there further around the pole teeth Z4, Z5, and is finally connected to the lamination L17, so that via the shorting bridge K1 the lamellae L1, L9, L17 are electrically shorted to each other and brush contact with one of the fins L1, L9, L17, the fins L1, L9, L17 are at the same potential.
- the short-circuiting bridge K2 extends from the lamella L2 of the commutator 110 around the pole teeth Z7, Z8 to the lamination L18 and from this around the pole tooth Z5 to the lamination L10 so that the lamellae L2, L10, L18 are electrically connected via the shorting bridge K2 shorted to each other.
- the short-circuiting bridges K1-K8 extend around the pole teeth Z1-Z8 is to be understood in the present case as starting from a lamination L1-L24 on an axial front side of the rotor 11 (corresponding, for example, to the front side shown in FIG ) extend through a groove N12-N81 to a rear side of the rotor 1 1, pass along one or more pole teeth Z1-Z8 at the back, and are laid back to the front side through another groove N12-N81, to another Lamella L1 -L24 to be connected.
- the short-circuiting bridges K1 -K8 thus do not describe a complete turn around one or more pole teeth Z1-Z8, but are merely wrapped around one or more pole teeth Z1-Z8 as approximately half turns.
- FIG. 4 illustrates the laying of the shorting bridges K1 -K8 on the basis of the shorting bridges K1, K2 originating from the winding W1. From the other windings W2-W8 go in an analogous manner shorting bridges K1-K8, wherein a shorting bridge K1 -K8 each two windings W1 -W8 is assigned and correspondingly eight windings W1 -W8 and eight shorting bridges K1-K8 are provided.
- the shorting bridges K1 -K8 Due to the particular routing of the shorting bridges K1 -K8 in sections around two pole teeth Z1-Z8 and in sections around a pole tooth Z1-Z8 (see FIG. 4), it can be achieved that the influence of the shorting bridges K1 -K8 on the operating behavior of the DC motor 1 is negligible is low.
- the shorting bridges K1-K8 are flowed through during operation of the DC motor 1 of current and generate a corresponding magnetic flux in the pole teeth Z1 -Z8, the influence - in the proposed installation - can be kept low, so that the performance of the DC motor 1 through the course of the shorting bridges K1 -K8 around the pole teeth Z1-Z8 around is not or at least not significantly affected.
- the short-circuiting bridges K1 -K8 can even contribute to torque formation.
- Fig. 5 shows schematically the rotor 1 1 with attached to eight pole teeth Z1-Z8 eight windings W1 -W8 and correspondingly laid shorting bridges K1 -K8.
- FIGS. 6A-6G illustrate the manufacturing steps for winding the windings W1-W8 and the short-circuiting bridges K1 -K8 onto the pole teeth Z1-Z8 in connection with the fins L1-L24, wherein in FIGS. 6A-6G again a rolled-up representation of the DC motor 1 has been selected for easier overview.
- each pole tooth Z1-Z8 two windings W1-W8, W1 '-W8' are arranged on each pole tooth Z1-Z8. Attaching a plurality of windings W1 -W8, W1 -W8 'to each pole tooth Z1 -Z8 serves to speed manufacturing and also provides the possibility of using thinner wire.
- Each pole tooth Z1-Z8 carries a first winding W1-W8 and a second winding WV-W8 '.
- the first windings W1 -W8 and the second windings W1 '-W8' are here, together with the associated shorting bridges K1 -K8, KV-K8 ', each of a continuous wire in a simultaneous manner and thus wound parallel, so that windings W1 - W8, W1 -W8 'and shorting bridges K1-K8, KT-K8' can be wound simultaneously in a single operation without the need for subsequent operations to attach the shorting bars K1 -K8, KV-K8 '.
- Fig. 6A first shows the rotor 1 1 with its pole teeth Z1-Z8 before attaching the windings W1 -W8, W1 -W8 '.
- a winding W1 is arranged on the pole tooth Z1 and connected to the fins L1, L2 via winding arms W1 1, W12. This is based on the lamella L1, to which the wire 2A is attached, for example by hanging on a hook to wind the wire 2A from this lamination L1 to the pole tooth Z1 around and to lead to the blade L2.
- the winding W5 ' is arranged on the pole tooth Z5 with a further, additional wire 2B and connected via winding arms W51, W52 with lamellae L13, L14, in which case first the wire 2B is connected to the lamination L13 and, starting from this lamination L13, the winding W5 'is wound around the pole tooth Z5 and fixed to the lamination L14 in an electrically contacting manner.
- wires 2A, 2B are hooked into hooks on the slats L1 -L24, which are bent after the laying of the winding wires 2A, 2B, then the wires 2A, 2B then, for example by means of welding (hot caulking) to the slats Fix L1 -L24.
- shorting bridges K2, K6 ' are laid starting from the lamellae L2 (shorting bridge K2) and L14 (shorting bridge K6').
- the shorting bridge K2 in this case extends from the lamella L2 around the pole teeth Z7, Z8 toward the lamination L18 and from this around the pole tooth Z5 to the lamination L10.
- the wire 2A is immediately further pulled to wind the winding W4 on the pole tooth Z4 and connect it to the blade L1 1.
- the shorting bridge K6 extends from the lamination L14 about the pole teeth Z3, Z4 toward the lamination L6 and of this around the pole tooth Z1 to the lamination L22, where the wire 2B is further drawn to wrap the winding W8 'about the pole tooth Z8 and to connect to the lamination L23. Accordingly, the winding process is continued, wherein in the next step, shown in Fig. 6D, the shorting bridges K3 (starting from the lamination L1 1) and K7 '(starting from the lamination L23) and subsequently the windings W7 (subsequent to the shorting bridge K3 ) and W3 '(subsequent to the shorting bridge K7').

- one or both of the wire circuits U1, U2 forming the windings W1-W8 or W1 -W8 ', each consisting of a continuous wire 2A, 2B are not formed as closed rounds by the last shorting bridge K1 in the first wire circulation U1 and the last to be wound shorting bridge K5 'in the second wire circulation U2 are not or at least not completely executed, so that the wires 2A, 2B each with their ends are not connected to the same lamination L1 -L24.
- the wires 2A, 2B are connected with their beginning to the slats L1 and L13 (see Fig.
- this lamella L1, L13 is not occupied by both ends of the wire and accordingly carries only two wire connections, one originating from the wire end of the wire 2A, 2B and a second from mounting the other wire circulation U2, U1 during winding. Accordingly, the number of wire connections per lamination L1-L24 is equal to the number of wire loops U1, U2, ie two.
- wire loops U1, U2 are not designed as closed circuits, no change in performance.
- the not or at least not completely wound last shorting bridge K1, K5 'of the respective wire rotation U1, U2 is completely in each other wire U2, U1 provided so that an electrical connection of the associated slats L1, L9, L17 (for the shorting bridge K1) and L5, L13, L21 (for the shorting bridge K5 ') is formed by a corresponding shorting bridge KV, K5 of the respective other wire circulation U1, U2.
- the wire circulations U1, U2 are each wound from a continuous wire 2A, 2B, for which purpose, for example, the flyer winding technique or the needle winding technique can be used. This results in two so-called flyers, each forming a circulation U1, U2.
- three wire revolutions U1-U3 are wound to form three windings W1-W8 per pole tooth Z1-Z8 by the needle winding technique or the flyer winding technique using a single continuous wire 2.
- the continuous wire 2 is wound around the pole teeth Z1-Z8 in each case to form three windings W1-W8 per pole tooth Z1-Z8, with short-circuit bridges K1-K8 which connect the windings W1-W8 to one another and through grooves N12 -N81 be laid through.
- FIG. 7A-7C first show in tabular form a winding scheme in which three revolutions U1, U2, U3 are wound using a continuous wire 2 and the wire 2 is wound with a first wire end 20 on the first lamination L1 and with its second wire end 21 is also connected to the first blade L1, so that there is a closed wire loop.
- the present invention is not realized accordingly; the embodiment serves insofar as illustration only.
- the winding scheme first, starting from the lamination L1, the first winding W1 is wound on the pole tooth Z1, as shown schematically in FIG.
- the shorting bridge K2 for connecting the louvers L2, L18, L10 is routed through the slots N81, N67 to then wind the winding W4 on the pole tooth Z4 (the slots N12-N81 are in the tabular listing of FIGS. 7A-7C designated by the adjacent pole teeth, so that the groove N12 is designated, for example, as "Z1 / Z2", the groove N23 as “Z2 / Z3", etc., the groove N81 is designated as "Z1 / Z8").
- the first wire loop U1 is wound with the windings W1-W8 as shown in FIG. 7A, winding W1 first and winding W6 first.
- the first wire turn U1 then returns to the fin L1 and, using the same continuous wire 2, the second wire turn U2 of Figure 7B is then wound in an analogous manner.
- the third wire circulation U3 is then wound as shown in FIG. 7C, wherein the third wire circulation U3 in the example not embodying the invention corresponds identically to the wire circuits U1, U2 and thus again on the Slat L1 ends.
- the wire ends 2 with its ends 20, 21 thus on the same blade L1 which is thus a total of four times occupied and thus carries four wire connections.
- the last shorting bridge K1A of the last wire revolution U3 is not completely executed and thus does not terminate on the lamination L1 but on the lamination L9.
- the last section of the shorting bridge K1 is omitted in the third wire circulation U3.
- the wire 2 thus goes out with its first end 20 of the lamella L1, but ends with its second end 21 not on this, but instead on the lamella L9.
- the last wire circulation U3 is not closed in itself. However, this has no electrical influence on the operating behavior, because the shorting bridge K1 is completely provided both in the first wire circulation U1 and in the second wire circulation U2 and thus the fins L1, L9, L17 are interconnected by the shorting bridges K1 of the wire circuits U1, U2. The incomplete execution of the shorting bridge K1A in the third wire circulation U3 thus has no electrical influence on the operating behavior.
- FIGS. 8A-8C compared to the winding scheme of FIGS. 7A-7C, the last section of the shorting bridge K1 of the third wire circulation U3 (see the last two lines of FIG. 7C) is not completed, so that the incomplete shorting bridge K1A results.
- the incomplete shorting bridge K1A connects the slats L17 and L9 with each other, but not with the other slat L1, as was realized in the short circuit bridge K1 actually to be provided.
- an incomplete shorting bridge K1B can also be provided at the beginning of the first wire revolution U1.
- the end 20 of the continuous wire 2 starts from the lamination L9.
- the shorting bridge K1 is completely omitted in the third wire circulation U3.
- the wire 2 is connected with its ends 20, 21 with different lamellae L9, L17.
- the third wire circulation U3 is not closed as a result.
- the wire 2, 2A, 2B For connection with the slats L1 -L24, the wire 2, 2A, 2B, as shown schematically in Fig. 10, hung in hooks 3 of the slats L1 -L24, wherein after complete attachment of the wire, the hooks 3 bent and the wire connections 22, which can form the wire 2 or the wires 2A, 2B with the hook 3, can be fixed. Because the ends 20, 21 of the wire 2 or the wires 2A, 2B terminate at different lamellae L1, L9, there are exactly as many wire connections 22 per lamination L1-L24 as there are wire loops U1 -U3. Accordingly, the hooks 3 are only to accommodate this number of wire connections 22 to dimension.
- the brush-commutated DC motor is not limited to the specifically specified here numbers of excitation poles, pole teeth and fins. In principle, a different number of excitation poles (corresponding to an integer multiple of 2), pole teeth and lamellae can also be used.
