The technical field to which the invention relates.

The present invention relates to a method of manufacturing a rotor winding of an electric machine, characterized in paragraph 1 of the claims, as well as to the electric machine manufactured by this method, the rotor winding, as described in paragraph 10 of the claims.

The level of technology

From the publication DE 102004062813 A1 known solution, in which the number of grooves and the pole teeth, alternating around the circumference of the commutator of the rotor is chosen different from the number located in the stator poles of the excitation. The number of so-called coils (winding sections), wound on a separate rotor teeth equal to the number of collector plates, but twice the number of pole teeth, and the number of grooves. When this coil wound on the pole teeth with a uniform distribution on him, entered with a specified step by collector in contact with the cockerels plate collector. Starting with the first coil, each of the rest of you consistently and continuously wound coils wound on the pole tooth for which the angular deviation from the electrical angle defined by the pole division, is the smallest.

Problem options for implementing known solutions are presented and described in this publication, is that to reach the cat is NIS plate collector magnet wire, with one hand, remove the chicken plate collector directly from the groove, and on the other hand, it has to lead from the groove by a greater segment of a circle, and such situations; often alternate. In this case, as the continuous winding wire such laid along the segment of a circle magnet wire slips over sections of the wire, output directly to the grooves in the direction of the collector plates, which complicates the introduction of the following winding coils in contact with the cockerels plate collector.

In embodiments of the invention, depicted in Fig and 10 of this publication, magnet wire hangs males of the plates of the collector so that the angle between the part of the wire connected to the plate of the collector, and a piece of wire, suspended from plate collector is quite sharp, with the drawback that formed in this way a loop of wire on the chicken plate springs. Since the introduction of magnet wire in contact with the cock by the method of so-called hot deformation insulating varnish magnet wires in the area of the loop when the melt is removed, in this case, there is a danger of short circuits with ears of magnet wire on an adjacent Petushki.

Disclosure of inventions

Proposed in the invention is a solution aimed at eliminating p. oblem ensuring contact improving conditions strip magnet wire both males plate collector, as well as preventing critical springback loops of wire.

A method of manufacturing a rotor winding of an electric machine, as claimed in paragraph 1 of the formula has the advantage that the springback of the loops of magnet wire on Petushki plate collector is greatly reduced due to the fact that between fed by the cock and led out from it plots magnet wire is at least one pole tooth and thus provided sufficient girth cock. Another advantage of the invention lies in the fact that during the continuous winding of these coils (winding sections) magnet wire does not tend to slide into a reservoir in the area between the coil and cock, as between summed up by the cock and led him winding wire is not more than two pole teeth, and therefore, it is possible to avoid strip magnet wire with more substantial circumferential component. Of course, these advantages are inherent electrical machine, the rotor winding which is manufactured by the method according to paragraph 1 of the claims.

In dependent claims characterized expedient embodiments of the invention, the developing signs of paragraph 1 of the formula./p>

Thus, improvement strip magnet wire and ensuring its uniformity from a collector of the rotor is achieved in that at least part of the continuously wound each other coils winding magnet wire withdrawn from the coil to the plate of the collector and from the plate collector to the coil, is passed between the other two pole teeth located closer to the plate collector. It is necessary to ensure that between the corresponding plate collector and noise between the pole teeth of the plot magnet wires were not more than two pole teeth. As a possible option for such performance anchors, in which between the collector and the pole teeth of the armature there is enough space, it may make sense winding in which, preferably for the first part continuously wound each other coils, magnet wire away from the coil to the plate collector, as well as from the plate collector to the next coil means mounted on the shaft of the rotor support ring, and the coil is displaced around the circumference of the rotor relative to the respective plates of the collector by at least 90°.

To reduce the ripple torque and improving commutation, it is advisable to reduce the inductance in the pole teeth that achievement is highlighted by winding at least coils with an angular deviation with respect to the pole division with their distribution on the two opposite pole teeth. In addition, due to this radial components of the forces on the opposite pole teeth arising energized coil currents are equal, and therefore, the amount mutually exclusive. This distributed implementation of the coils with their winding on two opposite pole teeth it is advisable to apply to all coils. In this case, the manufacturer of the winding of the rotor is particularly simple if the distributed coil wound continuously one after another in the form of series-connected halves of the coils. Instead, if necessary, each of the distributed coils can be wound in the form of halves of the coil are connected in parallel to their common start and end plates of the collector. For symmetric patterns coils suitable option, in which the coil with an angular deflection coils and without angular deviation is wound continuously one after another in a uniform sequence. In the private embodiment of the invention for achieving favorable ripple torque, or even weight distribution around the circumference of the rotor may be appropriate, at least part of the coils distributed over the opposite pole teeth, reel half of these coils with different number of turns.

The implementation of the invention

In figure 1 for the first variant embodiment of the invention schematically in a front view depicted and indicated by item 10 excited by a permanent magnet pole of the direct current motor, representing an example of an electric machine is us. Such machines are used preferably for servo drives, fans, etc. in vehicles and at high loads must operate reliably as possible during the entire lifetime of the vehicle. In accordance with this design should be durable. Electric machine 10 has a six-pole stator 11, which through the working air gap 12 communicates with the collector rotor 13, hereinafter referred to collectively simply by the rotor. The rotor 13 includes a package of 14 core fixed supported on two sides of the shaft 15 of the rotor. Around the circumference of the package 14 of the core there are ten equally spaced pole teeth Z, between which made grooves for placement in total, twenty-coil's winding 18 of the rotor. When this coil's winding wound machine pairs around each pole teeth z Coil S in a special way connected with the reservoir 16, the shaft 15 of the rotor from the front face side of the package 14 of the core. The manifold 16 has twenty evenly distributed around the circumference of the plates L, interacting with the two stationary carbon brushes B1 and B2. Carbon brushes are spaced from each other by 180° and to ensure the operation of the electric machine is supplied by a constant current. However, ten pole teeth Z of the rotor 13 vzaimode setout with three pairs of poles excitation of the stator 11. To get as low as possible ripple torque of the electric machine, the number of pole teeth different from the number of poles P of the excitation.

Figure 2 shows a detailed schematic is shown in figure 1 of the electric motor 10 DC, which explained in more detail below, the method of winding for the manufacture and distribution of coils S pole teeth Z of the rotor 13. In the drawing shows a six-pole stator 11, ten pole teeth Z1-Z10, the first two coils S1 and S2, as well as twenty plates L1-L20 collector 16 (also called the collector plates). The position of the first coil S1 is chosen arbitrarily and is necessary in this case, a third pole tooth Z3. Next, the first pole tooth Z1 with the first coil S1 corresponds to the middle of the North pole of the stator 11. This correspondence also randomly selected. In addition, a randomly selected according plates L collector and the pole teeth Z is chosen in this case so that the first pole tooth Z1 was exactly at the level of the gap between the plates L5, L6 collector 16. This place has on the circumference of the rotor angular position φ=0°, as shown in figure 2. It follows that the adjacent pole teeth Z2 is in position 36°, and the next gap between the plates of the collector is in position 18°. Then we who are caught, all coils S are entered his early contact with the primary plate La, and its end is in contact with the end plate Le collector. Fig: 2 plate L1 is a randomly chosen initial plate La1 to the first coil S1. Therefore, based on the position selected in this case the plate L1 between the initial plate La1 coils S1 and provided for the coil pole tooth Z3 is obtained angular shift φ₀average of 63°. In figure 2 the coil S1 is in the optimal position - in the middle of one of the poles of the stator 11. For this angular position deviation (deviation from the electrical angle is zero: Wf=0°.

To coil's can be had in a continuous mode to wrap the pole teeth Z on the type of wave windings, for all coils winding S is set to step Y winding by collector (collector step), which guarantees the possibility of introducing end of each coil in contact with a free plate L of the manifold. Figure 2 provides a step Y by collector of a seven plates, i.e. Y=7.

As already shown in detail and discussed in the above publication DE 102004062813 A1, first of all coils in a row define the starting plate La of the collector and the end plate Le collector. Then, for each coil winding of the rotor 13, is wound over the coil S1 at the first crawl is bmode, for each pole teeth Z detect the angular deviation with respect to the pole division of the stator, namely the deviation Wf angular position of this tooth from the corner defined by the pole division of the stator 11, using the following formula:

(1) Wf(j)=cos[2π*p/z*(j-Lai/M)]

Now on the basis of the angular deviation of the second coil S2, calculated in this way for each pole teeth Z, in the next step, determine the pole tooth on which the coil S2 will have the smallest angular deviation Wf. Thus, for the coil S2 is the smallest angular deviation Wf=18°, or the greatest cosine angular deviation max=0,951, falls on the pole tooth Z5. The same angular deviation occurs and the pole teeth of the Z8, Z10 and Z3, which can be used for optimal coil terminals.

Thus, for all coil's windings determine the start and end plates La and Le collector, as well as optimum for the respective coil pole teeth z In the above publication, these values are necessary for winding machine table of winding data, with each coil winding wire guide directly from the initial plate La of the collector to the coil S and the coil S to the end plate Le collector. However, in the manufacture of the windings with a higher number of coils at the same time, the problems arise with the wire strip between the collector 16 and the coils S, making the necessary ordering of the connections of the coils to the plates of the collector 16.

On figa-3E schematically presents different ways of introduction of magnet wire in contact with the collector plates. When this magnet wire 17 is wrapped around the male plates 16A L manifold. In the future, such decisions on accession of the wire, in which the magnet wire is output from the cock 16A of the plate L the collector directly to the slot N, is called a direct connection wires. This type of shots used in the variants shown in figa, 3b, 3C and 3D. Curled hooked wire in the future are joining in which the magnet wire 17 from the cock 16A plate collector 16 is output to the slot N by strip around the shaft of the rotor to fit the support ring 19 of insulating material positioned between the manifold 16 and the package 14 of the core. This type of shots used in the variants shown in Figg and 3E. Because the so-called hot deformation used to ensure contact of the plates L collector winding wire, cock 16 is bent electrode-stamp towards the plate collector with the formation of the hook and under the action of electric current is connected by fusion with the winding wire 17, the insulating varnish on winding p is the gadfly 17 in the area of the envelope cock loops 16A 17c during melting is removed. It is important that the loop 17c covered cocks 16A as closely as possible after their formation by direct or Curling shots magnet wires to males 16A less springy avoid short circuit cockerels 16 adjacent plates L manifold through these loops 17c. This is true for the variants shown in figa, 3b, 3C and 3D, in which the magnet wire is applied to the cock with one hand and away from the chicken to the other side. Direct lifting magnet wire shown in figa embodiment, each of the connecting points of the winding wire to the plate collector between the input to the plate and taken away from her plots magnet wire 17 are two pole teeth z shown in figb option between fed to the plate and taken away from her plots magnet wire 17 are alternately adjacent connection points of the wires to the plates respectively one pole tooth and two pole teeth Z, as shown in figv option between fed to the plate and taken away from her plots winding wire 17 is in each case one pole teeth z cinched Tight, mallapragada loop 17 is obtained by bounding the lifting magnet wires to males 16A, shown in Figg, because in this case, magnet wire 17 ACC is out for cock 16A on one side and away from the chicken to the other side. To avoid the same should be problematic variants shown in Figg and 3E. Direct lifting magnet wire shown in Figg option between fed into the cock 16A and exhaust on it by sections of the winding wire 17 is formed only a small acute angle, since the magnet wire is connected to the plate L of the manifold and away from her almost vertically in the same groove. In this case, with increasing thickness of the wire magnet wire 17 will bounce in the area of the loop 17c that there is a risk of closure on other plate collector. The danger of getting loops 17c with increased prajnanam is shown in fige version, where you curled the hooked wire input and exhaust sections of winding wires 17 pass between the cockerels coils 16A and S on the support element 19 from the respective plates to the respective grooves are almost parallel and in the same direction.

In order to optimally use the space between the collector 16 and the package 14 of rotor core 13 for the connection of the terminals of the coils S to the plates L manifold, in particular in the case of a large number of coils, it may be expedient introduction the first part of the continuously wound coil S in contact with the plates L reservoir through the by-pass shots shown in Figg, then the ri continuous winding of the last part of the coils these coils can be put in contact with the plates L collector by direct shots. For direct collection using one of the solutions shown in figa, 3b or 3C. Thus, for the given below of embodiments of the invention required to manufacture the winding of the wrapping table data amount so that at least for wound least part of the coil's magnet wire 17, entered into contact with the cock 16A of the plate L of the collector, were summed up to the plate L manifold with one hand and played from it on the other hand, and that between the groove N, from which the winding wire 17 is connected to plate L collector, and a groove to which the magnet wire away from the plate L reservoir was at least one pole tooth Z, but not more than two pole teeth z To achieve this it is necessary, at least for one part of the continuously wound each other coils S, skip magnet wire 17, withdrawn from the coil S to the plate L of the manifold and from the plate L of the collector to the coil S, between two other pole teeth Z, located closer to the said plate L collector, and between the plate L collector and noise between the pole teeth of the plot magnet wires may be no more than two pole teeth z

It wound left in the first half S1a coil with fourteen turns, the end of the coil is directed again to the right and enter in contact with the plate L8 collector. From this plate collector magnet wire guide right to the pole tooth Z10. It wound right half S2a coil with thirteen turns, after which the end of the coil is directed to the right and enter in contact with the plate L15 collector. From this plate collector magnet wire guide right to the pole tooth Z5. It wound left half S3a coil with fourteen turns, after which the end of the coil is directed to the right and enter in contact with the plate L2 header. From this plate collector magnet wire is sent again to the right to the pole tooth Z7. It wound right half S4a coil with thirteen turns, after which the end of the coil is directed to the right and enter in contact with the plate L9 collector. From here a winding machine for the manufacture of the first half S5a-S20a other coils fulfills all further rows of the first half is shown in Fig table wrapping data. At figa transfer coil wires from the right side to the left side of the deployed schema of the rotor is indicated with a dashed line. Introduction halves Sa coils in contact with the plates L collector is in this case the way the Curling shots, shown in Figg, in which the magnet wire is given between the respective plate collector and a coil on the support ring 19, and the coil is displaced relative to the respective plates of the collector by at least 90° around the circumference of the rotor.

On figb in the form of an expanded diagram of the rotor is schematically represented below making the second half of Sb coils in accordance with section 6 shown in Fig of the wrapping table data.

After winding on the pole teeth Z3 of the first half of S20a twentieth coil and the introduction of the end of the respective coil plate L1 collector, magnet wire 17 is directed from the plate L1 manifold to pole tooth Z3. It wound right half S1b coil with fourteen laps and then the end of the coil is introduced into contact with the plate L8 collector. From this plate collector magnet wire out through the groove 5 to the rear side of the rotor and then to the pole tooth Z5 wound left half S2b coils twelve coils. Then the end of the coil is directed to the back side of the rotor is brought out through the groove 7 and the collector is introduced into contact with the plate L15 collector. Taking the lead from this plate collector, pole tooth Z10 wound to the right half S3b coil with fourteen turns, and enter the end of the coil in contact with the plate L2 to the of lectora. From this plate collector magnet wire out through the notch N2 to the rear side of the rotor and then to the pole tooth Z2 wound left half S4b coils twelve coils. Then the end of the coil is directed to the back side of the rotor and out through the slot N4 to the side of the collector, where it is introduced into contact with the plate L9 collector. Starting from here, the pole teeth continuously wound each other the second half S5b-S20b all subsequent coils, thus working off a winding machine, the second half is shown in Fig table wrapping data. Introduction halves Sb coils in contact with the plates L collector is carried out in this case by direct shots shown on figa scheme, according to which between the input and exhaust sections of the winding wire of the corresponding plates of the collector are two pole teeth z Separation of the manufacturing process of the coil windings on the two lines as shown in Fig table wrapping data ensures that the connection of the terminals of the coils of the first line of the winding (the first part of the table winding data winding) to the plates L of the manifold by-pass the collection does not prevent connection of the terminals of the coils of the second line winding to the plates L collector by direct shots, and Vice versa direct PR is Ceplene conclusions coils in the second line prevents the Curling of the connection in the first line.

Unlike the previous variant implementation of the invention in the sixth embodiment are partially shown in Fig table wrapping data with changed for forty halves of the coils, the direction of winding.

In addition, in the first line of the continuously wound halves S1a-S20a coils points of connection of the coils to the plates L collector are implemented not by the Curling shots shown in figa, and by direct shots shown in figb. This requires more guiding the ends of the coils on the back side of the rotor to pass them through the additional grooves N, are closer to the corresponding connection plate collector. On Fig in the form of an expanded diagram of the rotor presents the following manufacturer halves S1a-S4a coils in accordance with section as shown in Fig of the wrapping table data.

First, magnet wire 17 starting 17A is introduced into contact with the plate L1 collector. From this plate collector magnet wire out through the groove 10 to the rear side of the rotor and is then guided to the pole tooth Z8. It wound right coil S1a with twelve coils and then the end of the coil is brought out through the slot N5 to the side of the collector, where it is introduced into contact with the plate L8 collector. From this plate collector magnet wire out through the AZ N3 to the rear side of the rotor and then through the slot N2 fail to pole tooth Z10. It wound left coil S2a with twelve coils and then the end of this coil is introduced into contact with the plate L15 collector. From there, magnet wire out through the groove 7 to the rear side of the rotor and then down to the pole tooth Z5. It wound right half S3a coils twelve coils and the end coil output on the rear side of the rotor and through the slot N2 to the side of the collector, where it is introduced into contact with the plate L2 header. From there, magnet wire out through the groove 10 to the rear side of the rotor and thence through the slot N9 deduce to the side of the collector. From there to the pole tooth Z7 wound left half S4a coils twelve coils, after which the end coil is introduced into contact with the plate L9 collector. Then in the same way make all the other half S5a-S20a and S1b-S20b coils. Attach the coils to the plates L of the collector in this case is unlike figa by direct collection of magnet wires to the plates L of the manifold instead of the Curling shots.

The possibility of carrying out the invention is not limited to the above options, since under the given conditions on the number of pairs of poles, the number of teeth and a winding step for the collector, you can get many combinations of values for the implementation of the windings of the rotor shown in figure 1 of the electric machine 10. the button in versions of the winding without distribution coils on different teeth there is a possibility of split wound continuously one after the other coil's two, if necessary, of various sizes, lines, and introduction of the coils of the first line winding in contact with the plates L of the manifold by-pass shots. For the smooth introduction of the coils S in contact with the plates L manifold if necessary, may be a suitable option, in which the coil with an angular deviation of Wf and coil without angular deviation Wf continuously wound in a uniform sequence. Because in this case, at least part of the coil's magnet wire applied to the plates L of the manifold and exhaust from the plates L collector, you must pass through shallower groove, for best switching and less ripple torque can be a suitable option, in which at least part of the coils S, distributed by the opposite pole teeth Z, half of Sa and Sb of these coils will be nakativaetsa with a different number of turns, as shown in figure 10 and 12 tables winding data. The angular shift φ between the pole tooth 1 and the slit plate L1 collector is preferable to choose from so that this plate L1 collector not appeared on Rotel groove N, through which the winding wire is output from the plate L1 manifold to the coil S1.

Other alternatives proposed in the invention to the manufacture of the coil's windings of the rotor of the electric machine can be obtained due to the fact that in the first line of the continuously wound coil half of the distributed coils include in parallel to each other, and in the second line of the other half distributed coils include sequentially. Another alternative in the case of distributed coils may be that in the first line of the coil continuously wound first half of Sa coils, and the second line winding the second half of the Sb coil is wound continuously and consistently, again dividing each of them into two partial coils Sb1 and Sb2.
