Abstract

The invention relates to a method for producing windings of a travelling field machine and to a corresponding travelling field machine. When producing windings of a travelling field machine, the invention provides that a first starting slot and a first series of slots are appointed in a peripheral direction of a winding body so that the last slot of the first series of slots corresponds to the first starting slot. In addition, the winding is placed on the winding body, whereby the winding conductors, starting from a first face of the winding body, are arranged such that they run through the first starting slot to a second face of the winding body located opposite the first face. While travelling in the peripheral direction, said winding conductors run through the slots of the first series of slots in a meander-like manner and while alternating between the faces until reaching the first starting slot. From this first starting slot, the wiring conductors, while travelling counter to the peripheral direction, run through the slots of the first series of slots in a meander-like manner and while alternating between the faces until reaching a slot located adjacent to the first starting slot, whereupon they pass through the slot located adjacent to the first starting slot and terminate on the second face.

Description

Traveling field machine and method for producing windings of the traveling field machine

DESCRIPTION

Field of the Invention

The present invention relates to a method for producing windings of a traveling field machine and a traveling field machine with windings produced according to the invention.

In particular, the invention relates to windings of a traveling field machine and a method for producing the same, the windings being arranged on corresponding winding bodies in a meandering shape in one direction and then in a meandering shape in the opposite direction.

Background of the Invention

Traveling field machines (asynchronous, synchronous, rotary or linear machines) are known in the prior art, the term traveling field machines being understood to mean both motors and generators. Traveling field machines have a rotor and a stator, each with a winding body, on which the windings for the rotor and stator coil (s) are arranged. The windings arranged in corresponding grooves in the winding body should have the lowest possible magnetic leakage losses when generating the magnetic fields required for the operation of the traveling field machine. Furthermore, the filling factor of the slots, ie the ratio of the cross section of a slot and the cross section of a winding arranged in the slot, should be as large as possible in order to provide small-sized runners and stands. Furthermore, the winding overhangs (ie the areas of a rotor or a stator in which the windings are guided from one slot to the next slot via end faces of the corresponding winding former) should have small dimensions in order to enable traveling field machines of a small design and magnetic leakage losses to reduce. Furthermore, the windings of a traveling field machine should be easy to manufacture.

It is known to use windings made of individual rod-shaped or U-shaped metallic conductors with a round or rectangular cross-section instead of winding wires in order to achieve higher filling factors for the slots on the one hand and to simplify the manufacture of the windings on the other hand. It is also known to use windings whose cross sections differ in the areas of the grooves and in the areas of the winding overhangs, preferably are smaller in the areas of the slots, whereby the dimensions of the winding overhangs can be reduced. In order to keep the magnetic leakage losses of a traveling field machine small, it is necessary that the conductors forming the windings form closed conductor loops. For this, in the simplest case, the conductors forming a winding are guided from one slot over one winding end to a next slot and from this over the other, opposite winding end to the first slot. Closed conductor loops also result if windings with a plurality of winding conductors are used which are meandered through grooves in a circumferential direction of the corresponding winding body, the different conductors of a winding being guided in each case via opposite winding heads.

Some of the windings for traveling field machines described above can only be produced in a complex manner, some have large winding heads and require a large amount of conductor material, as a result of which such traveling field machines have large dimensions and a high weight. Furthermore, these windings are sometimes subjected to high thermal loads and have high leakage losses.

To reduce these problems, GB 1 329 205 suggests using prefabricated conductor parts with a zigzag shape. Around windings with closed conductor loops To manufacture, two preformed conductor parts are used in grooves of a winding body for each winding, with two conductor parts of a winding running in opposite directions in a zigzag shape. Furthermore, two conductor parts of a winding are connected to one another at a contact point in such a way that a continuous winding line is formed. The disadvantage here is that exact tolerances have to be adhered to in the manufacture of corresponding winding bodies and preformed conductor parts in order to ensure the insertion of the conductor parts. Furthermore, the number of slots into which preformed conductor parts can be inserted is limited, since conductor parts according to GB 1 329 205 can only be used if they enclose less than half the circumference of a corresponding winding body. In addition, the preformed conductor parts of all phases lie flat on top of one another in the winding overhangs, as a result of which large cavities are created which lead to the large design of such a traveling field machine.

OBJECT OF THE INVENTION It is an object of the present invention to solve the above problems in the prior art. In particular, magnetic stray losses from traveling field machines are to be reduced and high numbers of turns are to be made possible with the smallest possible dimensions of the winding heads of a traveling field machine.

Solution according to the invention

The object of the invention is achieved by a method according to claim 1 and a traveling field machine according to claim 10.

In the method according to the invention for producing windings of a traveling field machine with a winding body for a rotor and / or a winding body for a stator, at least one winding is produced on the winding body of the rotor and / or the stator as follows. It becomes a first starting groove and a first sequence of grooves in one The circumferential direction of the winding body is determined, the first sequence of grooves being determined such that the last groove of the first sequence of grooves corresponds to the first initial groove. The conductors forming the winding are then arranged on the winding body. Here, the winding conductors are led from a first end face of the winding body through the first starting groove to a second end face of the winding body opposite the first. The winding is then guided in a meandering shape through the slots of the first sequence of slots in the circumferential direction and alternately on the end faces until the first starting slot is reached. Now, starting from the first starting slot, the winding is again meandering in the opposite direction to the circumferential direction through the slots of the first sequence of slots and alternately on the end faces to a slot adjacent to the first starting slot and through this slot, in order to end on the second end face.

The meandering guidance of the winding conductors through the grooves and the meandering guidance of the winding conductors through the grooves in the opposite direction result in windings with closed conductor loops. Here, windings of one phase each have only two connections. Furthermore, the conductors are arranged on the winding heads in one direction and the conductors in the opposite direction on opposite winding heads. This procedure makes it possible to keep the magnetic leakage losses low, since windings in one phase only have closed conductor loops. In addition, the dimensions of winding heads of a traveling field machine comprising such a winding are small, since conductors of windings of one phase are not guided in parallel on the winding heads.

The object of the invention is also achieved by a traveling field machine with a winding body for a rotor and / or a winding body for a stator, the winding bodies in each case between a first end face and a second grooves arranged opposite the first end face include at least one winding. In particular, the one winding of the rotor and / or the stator comprises at least one conductor which, starting from the first end face of the winding former through a first starting groove to the second end face of the winding former, meanders through grooves of a first sequence of grooves in a circumferential direction of the winding former and alternately on the end faces to the first starting groove, from the first starting groove in a meandering shape opposite to the circumferential direction through the grooves of the first series of grooves and alternately on the end faces to a groove adjacent to the first starting groove and ending at the second end face.

Advantageous Embodiments of the Invention In order to produce a further winding on the winding body of the rotor and / or the stator, a slot of the first sequence of slots, which is in the first sequence of slots in the circumferential direction immediately before or after the first starting slot is arranged as the second initial groove. Furthermore, a second series of grooves is defined in the circumferential direction, so that the last groove of the second series of grooves corresponds to the second initial groove. The conductors forming the winding are then arranged on the winding body, the winding conductors starting from the second end face of the winding body through the second starting groove to the first end face of the winding body, meandering through the grooves of the second series of grooves in the circumferential direction and alternately the end faces up to the second starting groove, from the second starting groove in a meandering manner in the opposite direction to the circumferential direction through the grooves of the second sequence of grooves and alternately ending on the end faces up to the second starting groove and through the second starting groove on the first end face.

If two windings have been arranged on a winding body in the manner described above, it is preferred to connect these windings into one winding by connecting them to the first or end of the second end of the conductor of the windings are connected. In this way, the connections of a winding lie on a winding head (ie on one end face of the winding former) without the need to use additional conductors, which only serve as connecting conductors and are therefore not attributable to the winding.

Proceeding from this, the connection of windings of a winding head can be additionally facilitated if the lines of all windings of a winding body begin and end on the first or on the second end face of the winding body. The winding heads are also reduced in this way.

In order to arrange more than one winding on a winding body for one phase, the first starting grooves of different windings of a winding body should be defined in such a way that at least one groove is arranged between the starting grooves.

If rod-shaped conductors are used to arrange a winding and are arranged in corresponding slots, it is possible to optimize the filling factor of the slots. A further reduction in the size of the winding heads can be achieved if the rod-shaped conductors arranged in grooves are flexible

Conductors are connected accordingly. The flexible conductors guided on the end faces of the winding former also simplify the electrical connection between the rod-shaped conductors arranged in the slots.

Instead of rod-shaped conductors, individual U-shaped, L-shaped and / or S-shaped conductors can be used when arranging a winding.

In order to produce windings for a three-phase machine, at least three windings must be arranged on the winding bodies of the rotor and the stator. In the traveling field machine according to the invention, it is preferred that at least one further winding of the rotor and / or the stator is present. The further winding comprises at least one conductor, which starts from the second

End face of the corresponding winding body through a second starting groove, which is arranged in the first sequence of grooves in the circumferential direction immediately before or after the first starting groove, to the first end face, meandering through grooves of a second sequence of grooves in the circumferential direction and alternately on the end faces is arranged up to the second starting groove, from the second starting groove meandering against the circumferential direction through the grooves of the second sequence of grooves and alternatingly arranged on the end faces to the second starting groove and through the second starting groove on the first end face.

Furthermore, two of the windings of a winding former described above can have a connecting conductor which terminates the conductors of the ends of the first or second end face

Windings connects. In particular, it is preferable that the ends of all windings of at least one winding body are arranged on the first or on the second end face.

In order to arrange additional windings on a winding body, at least one groove should be arranged between the starting grooves of different windings of a winding body.

In addition, it is possible to use rod-shaped conductors arranged in corresponding slots for the winding of a traveling field machine, which are preferably connected by flexible conductors, for example conductors guided on the end faces of the corresponding winding body.

As an alternative or in addition, U-shaped, L-shaped and / or S-shaped conductors can also be used. A rotating field machine is provided if at least three windings are arranged on the winding bodies of the rotor and the stator.

Preferred embodiments of the present invention will be explained with reference to the accompanying figures.

Fig. 2 shows a schematic representation of three windings according to the invention in slots of a winding body.

Fig. 3 shows a schematic representation of another

Embodiment of a winding according to the invention in grooves of a winding body.

FIG. 4 shows a schematic illustration of the embodiment from FIG. 3 with three windings according to the invention in slots of a winding body.

DESCRIPTION OF PREFERRED EMBODIMENTS FIGS. 1 to 4 are schematic representations of grooves in a winding body 10 (not shown) for a stator or a rotor (not shown). The figures schematically show the surface of the winding body 10, which has the grooves 1R1, ..., nT2.

Furthermore, it is assumed that the winding body 10 has a substantially circular cross section in a plane perpendicular to the longitudinal axis of the grooves 1R1, ..., nT2. Therefore, the last slot nT2 of the winding body 10 is followed by the first slots 1R1, ..., 1T2 when the slots 1R1, ..., nT2 are viewed in a circumferential direction R. This has been taken into account in FIGS. 1 to 4 in that the last groove nT2 in Grooves 1R1, ..., 1T2 following the circumferential direction R are shown both at the beginning of the groove sequence shown above in the figures and at the end of the groove sequence shown below in the figures.

The production of a winding R1 will now be explained with reference to FIG. In order to arrange the winding R1 on the winding body 10, a first starting groove 1R1 and a first sequence of grooves 2R1, 3R1, ..., nRl, 1R1 are defined. Thus, the last groove of the first sequence of grooves 2R1, 3R1, ..., nRl, 1R1 corresponds to the first starting groove 1R1.

Starting from a first end face 12, which forms a winding head of the winding body 10, the winding R1 is guided through the first starting groove 1R1 to a second end face 14, which forms the other winding head of the winding body 10. The winding R1 is guided via the second end face 14 to the first slot 2R1 of the first series of slots and through this back to the first end face 12. Thereafter, the winding R1 is guided via the first end face 12 to the next slot 3R1 of the first series of slots and through this back to the second end face 14. In this way, the winding R1 is guided in a meandering manner through all the slots of the first series of slots and alternately over the end faces 12, 14 until the last slot 1R1 of the first series of slots is reached. Since the last slot 1R1 corresponds to the first sequence of slots of the first starting slot 1R1, two of the conductors forming the winding R1 are arranged in the slot 1R1. This is indicated in Figure 1 by the dashed lines.

So far, the winding R1 has been guided in the direction of the circumferential direction R of the winding body 10. The winding R1 is now continued in a direction opposite to the circumferential direction R of the winding body 10. For this purpose, the winding R1, starting from the last slot 1R1 of the first series of slots or the first starting slot 1R1, becomes meandering against the circumferential direction R through the slots of the first series of slots guided . Consequently, the winding R1 is now guided through the slots nRI, ..., 3R1, 2R1 and alternately on the end faces 12, 14. Starting from the slot 2R1 of the first series of slots, the winding R1 is not led back to the first starting slot 1R1, but to an adjacent slot 1R2 and through this to the second end face 14. The resulting course of the winding R1 is shown in FIG. 1.

If, using the manufacturing method described above, several windings are to be arranged on the winding body 10, the winding diagram shown in FIG. 2 results for the case of three windings R1, S1, T1 arranged on the winding body 10.

The windings Rl, Sl, Tl thus obtained only comprise completely closed conductor loops, as a result of which the magnetic stray losses are kept small. Furthermore, the windings R1, S1, T1 each have only two connections, which can be seen in FIG. 2 above. In order to obtain a three-phase machine, the windings R1, S1 and T1 are each assigned to one of the three phases.

With reference to FIGS. 3 and 4, the production of further windings on the winding body 10 is described in the following, this production for the sake of clarity

Example of a winding R2 is explained in more detail (see Figure 3).

In order to produce the winding R2, a second starting slot 2R2 and a second sequence of slots 3R2, ..., nR2, 1R2, 2R2 are defined. Thus, the last groove 2R2 corresponds to the first series of grooves of the second starting groove 2R2. Starting from one of the end faces 12 or 14, the winding R2 is guided through the second starting slot 2R2 to the opposite end face 12 or 14 and via this to the first slot 3R2 of the second sequence of slots. In a manner comparable to the production of the winding R1, the winding R2 is through the slots of the K) N),.

se has reached an increased number of turns. Even if the connecting conductors VR, VS and VT are arranged on one of the end faces of the winding body 10 in FIG. 4, it is possible to arrange the connecting conductors VR, VS and VT on different end faces of the winding body 10. The arrangement of the connecting conductors VR, VS and VT is determined by the windings or their conductors as well as the desired shape of a winding body provided with the windings or the type of traveling field machine.

The windings can be constructed using rod-shaped conductors. The cross section of such rod-shaped conductors preferably corresponds to the cross section of the grooves in order to achieve the highest possible filling factor of the grooves. The electrical connection of the conductors arranged in the grooves can be established by means of appropriately preformed rigid conductor elements or by means of flexible conductors. The use of flexible conductors enables a compact structure of the winding body 10 provided with windings. In particular, the winding heads can be reduced in this way.

As an alternative or in addition to the rod-shaped conductors, U-shaped conductors can also be used, the legs of which are arranged in corresponding grooves. L-shaped and / or S-shaped conductors can also be used.
