The level of technology

This end plate of the stator already known from the patent DE 4321540 C2. There is shown an electric motor with magnetic drive stator having two connecting buildings with cameras, which are located diametrically opposite each other on the outer edge of the free end surface of an end plate of the stator and which are introduced and secured the ends of the winding. However, the disadvantage of this motor is that for the external connection of the coils of the stator are required at least two plug-in connectors of the engine, and for further internal electrical structural elements of the motor requires additional external connections.

Disclosure of inventions

The basis of this is bretania have the task to provide economical to manufacture engine manifold, in particular universal motor, in particular for use in a household appliance.

The above problem is solved by an end disk of the stator with signs of paragraph 1 of the claims. Preferred and expedient embodiments of the invention are subject of the dependent claims.

In the end disc of the stator of the above type according to the invention the disk is only connecting terminal for electrical contact of at least one internal electrical structural element of the commutator motor in the plug block placed at least one relevant to this constructive element contact element. This structural element may be carbon brush and/or thermal and/or tachometer. Thus it is possible to reduce the number of required external connector that allows you to save these details.

According to the preferred embodiment for all internal electrical structural elements commutator motor in plug-in Board provides the necessary contact elements. Thus, for external connection of the stator coils, and all other internal electrical structural elements commutator motor requires only one connecting terminal. nasni plug of the engine preferably is a multi-pin connector, and the connector block is made suitable for making multi-pin connector, so to connect as both coils of the stator and the internal electrical structural elements rather use only one external connector. In addition, you can perform with the same end disk of different variants of the engine, in which differently distributed destination contact elements. Because it does not require the existence of supply of different end plates for different variants of the engine, reduced logistics costs in manufacturing different versions of the engine, thereby reducing production costs in General.

Connecting terminal for connecting structural element with a corresponding contact element preferably has a connecting element for connecting wires. The use of connecting wires, such as single wire or stranded cable allows you to easily attach a constructive element to the connecting element. If there are demountable connection, as, for example, plug-in or soldered connection, the constructive element in case of a defect or malfunction can be easily replaced. In addition, different variants of the engine is possible using different connecting elements.

In ternative embodiment, for compounds of structural element with a corresponding contact element in end plate integrated, in particular by injection molding, the connecting line. This connecting line is preferably in the form of a stamped grid. Thus, connection of the inner structural element is not tied to the possible position of the connecting elements of the connecting terminal as possible the accession of the structural element to the integrated connector, or to the stamped grid in another place an end plate of the stator.

End plate preferably has a device for placement of thermal relay, which serves as the switch in the armature circuit, and/or mount the temperature sensor in the air gap between the rotor and stator. In the end disc, designed for universal application, preferably already provided for both, and a corresponding bracket or fixture is already built, so the use of the same end plate of the stator as possible for variants of the engine with the switch in the armature circuit, and for variants with a temperature sensor.

In accordance with a preferred embodiment of the connecting terminal is formed in the end disc of the stator. In particular, both made of plastic, and the connecting terminal is preferably in the de single detail with magnetic disk. Because of this, do not require installation to connect the connecting terminal with an end disk. In addition, the end plate together with the connecting terminal is particularly easily manufactured using injection molding.

In accordance with a preferred improvement of the invention to the end disk of the stator for the mounting pole coils in positions of stator poles connected components of a single whole reference parts for the windings. Thus, the position of the windings relative to the axis of the engine is set already when winding coiling machine, and prevents their displacement in the radial direction, so there is no need for subsequent manual fixation of the windings of the stator in the region of their windshields parts, for example, using cable ties.

The connecting elements of the connecting terminal can be performed in different ways. In particular, at least one of the connecting elements in the form of a flat plug or shear pin connection or a welded hook. Preferably the making of connecting elements for connection of the wires of the stator winding in the form of a welded hooks and/or execution of a connecting element for joining structural element in the form of a flat plug. In this case, the wire winding is of the commutator, that is, as the ends of the coil, and the possible branches already winding on the winding machine are superimposed on the mounting hooks and subsequently automatically welded to weld the hooks. Internal electrical component manifold of the engine by one or more plug connectors attached to the respective flat plugs of the connecting terminal. This can be done either manually or automatically. Thanks to a detachable plug connection, the structural elements are replaced if necessary.

In accordance with the preferred embodiment, each of the connecting elements together with a corresponding contact element is made in the form of a metallic liner. The advantage of this design is that depending on the version of the engine is possible staffing connecting terminal end plate of the stator different number of inserts or liners of various shapes. The liner preferably is such that the connecting element in the form of a connecting pin is connected with a corresponding contact element in the form of a contact pin through the metal jumper. In particular, the liner is made of sheet metal, which enables to produce his osobennogo, for example, by stamping and bending.

The liners can be embedded in the connecting terminal, in particular by injection molding, with the result of automatic equipment connecting terminal inserts. Using injection molding end plate formed with and already equipped with liners connecting terminal is made in a single operation.

To equip the connecting terminal inserts it preferably consists of two parts and these two parts are designed to connect to each other by snapping and/or gluing. Because of this, it is particularly easy is the possibility of equipping the connecting terminal has a different number of inserts or inserts of different shapes for different variants of the engine. In particular, the location of the connecting terminal adapted for receiving inserts should be left blank, if the latter is not required for the appropriate version of the engine.

In a preferred embodiment of the improvements of the invention the contact element passes on the wrong side of an end plate of the stator, which is the connecting element and opposite the connecting element side. Consequently, it becomes possible to display external connection of the engine on the selection side a or side In the manifold of the engine, so depending on installation conditions commutator motor in the external device connecting an engine may be more comfortable of the two sides. In particular, both on the side of the end plate of the stator, which is removed from the package of the stator core, and on the side of the end plate of the stator facing the lamination, the connection terminal has one plug strip for alternative possibilities of making external plug connection of the engine. This makes it easy to insert the plug for the motor connection, resulting in a more favorable of the two possible positions. In particular, at least one of the connector pads is closed by a plug. In the plug-in pads are preferably provided by the elements of the latch to lock the stub when closing unused plug-in pads, or the cap is accordingly an unused plug the pad in the press fit, so that the contact elements unused connector pads protected by a cover against unwanted contacts.

According to the invention, the end disk of the stator is such that the shape of the surface of its fit to the package of the stator core substantially similar to the form the end faces of the lamination, so that the space in which WMO is it the rotor, koltseobrazno surrounded by an end disk of the stator. In a simplified embodiment, in contrast, the end plate can be performed such that it only partially covers the end surface of the package of the stator core. In particular, the end plate can also be limited to only part of the package core, passing in between the poles.

End plate according to the invention is used in the collector engines, in particular in the universal motors or engines sequential excitation, for household appliances, such as, for example, in drive motors for washing machines or dryers for clothes or fan motors for vacuum cleaners.

You should specify that the features of dependent claims in any way combinable with each other and with the features of independent clauses without deviation from the corresponding invention ideas.

Figure 1 shows the exploded view of structural elements of the stator pole universal motor 1. Universal motor 1 has a package 2 of the stator core with a strong first pole 3 for receiving the first pole coil 5 and marked the second 4 pole opposite the first pole 3, for making the second pole coil 6. For electrical insulation of the two-pole coils 5, 6 relative to the metal package 2 of the stator core is provided shaped insulators 7, 8, which are inserted in the axial direction in the grooves of the winding package 2 of the stator core and end plate 9 of the stator side and end plate 10 of the stator from the side to which solely opposite end surfaces of the package 2 of the stator core. In contrast to the end plate 9 of the stator side And end plate 10 from the side has additional connecting terminal 11. Further, on the side shown In the supporting plate 12, which closes the stator side and In which is placed, with the possibility of rotation of the rotor shaft of the engine (not shown) to its end by Century In the Central area, which contains the rotor shaft, the thrust plate 12 is integrated tachometer 13 to determine the speed of rotation of the rotor. For electrical contact manifold (not shown), together with the windings of the rotor on the outer side of the support plate 12 is set to the first holder 14 carbon brushes with the first carbon brush, and diametrically opposite to the first holder 14 carbon brushes - the second holder 15 carbon brushes with the second carbon brush.

In figure 2A end plate 10 of the stator-side B in accordance with figure 1, with its individual structural elements shown at an angle from above in the form on the side which is remote from the package 2 of the stator core, and figure 2b - angle bottom view of the side facing the package 2 of the stator core. In the end disc of the stator 10 side B in the place corresponding to the position of the first pole 3 of the stator formed by the first supporting element 16 winding for fastening of windings of the first pole to the carcass 5, and in the place corresponding to the position of the second pole 4 - second supporting element 17 winding for fastening of windings of the second pole coil 6. In addition, the end disc of the stator 10 side B in the area between the first and second support elements 16, 17 of the winding on the outer edge of the end plate 10 of the stator from the side there is a connecting terminal 11. The connecting terminal 11 has a first portion 18, which is made as a single unit with an end disk of the stator and on which are formed the projections 19 of the latches. In addition, the connecting terminal 11 has a second part 20, on which are formed the grooves 21 of the latch and which with the projections 19 of the tabs and the slots 21 of the latch is fixed to the first part 18. In the first portion 18 and second portion 20 of the connecting terminal 11 respectively are ten receiving fasteners 22 for liners 23, made of sheet metal. Each of the inserts 23 has a mounting plate 24 and pin 25, and the mounting plate 24 and pin 25 are connected to each other by a metal crosspiece 26. Further, to the first part 18 of the connecting terminal 11 side And attached the connector block 27, and the second part 20 of the connecting terminal 11 from the side attached to the connector block 28. Alternatively, we can also perform in the second part 20 with the side with the connector 28 as a whole with the connecting terminal 11, and thus with the end disc 10 of the stator, and the first part 18 with the connector 27 from the side And in the form of a removable or lockable latches on the details. When the liners 23 are nested in the receiving mount 22, and the first portion 18 and second portion 20 of the connecting terminal 11 are connected together by the tabs of the contact pins 25 of the inserts 23 are held in the connector block 27 by A, and the plug block 28 from the side, so that the external connector 48 of the motor connection can be inserted either in the plug block 27 by a or in the plug block 28 from Century to protect the contact pins 25 unused plug-in pads, respectively, 27 or 28, from unwanted contacts, provided by the stub 29, which can close unused connector block 27 or 28 with a press fit.

In addition, the end disc 10 from the side is provided In the bracket 30 to the switch 31 in the armature circuit. To ensure that the location of the temperature sensor in the air gap between the package 2 of the stator core and the rotor 47, including for alternative variants of the engine, in the end disc 10 of the stator side In addition provides holders 32 for temperature sensor or its connecting wires. In figure 3, the end disc 10 from the side shown with komplektov the authorized connection terminal 11, that is, with nested liners 23 and attached to each other on the latches of the first part 18 and the second part 20. Plug block 28 from the side is provided for making external connector for connecting unused connector block 27 from the side And is closed by a plug 29. You can run the second part 20 of the connecting terminal 11 with various connector blocks 28 on the side for different variants of the engine so that it was designed to make different, for example, 6-pin, 8-pin or 10-pin multi-pin plugs. In this case, no need to change the first part 18 of the connecting terminal 11, and with it the end plate 10 of the stator, since it is only necessary equipment connecting terminal 11 fewer liners 23 and, accordingly, a smaller number of connecting elements 24 or the contact elements 25. When you need to equip different engine variants many different plug-in pads 27 on the side And for making various external connectors 48 of the motor is connected, preferably - as mentioned above - to produce the second part 20 together with the magnetic disk 10 of the stator in a single piece, and the first part 18 of the connecting terminal 11 with the connector 27 from the side And connect with the second part 20 to recognize the sustained fashion terminal 11 as a separate structural element.

Shown in figure 3 the end disc 10 of the stator side In the switch 31 is already in the receiving bracket 30 to the switch. Switch 31 is attached to one of the mounting plates 24 made in the form of a flat plug 35 through the first connecting wires 33, which at the end remote from the switch 31, the ends of the slot 34 for flat plug. The switch 31 has a second connecting wire 36, remote from the switch 31, the end of which there is a second slot 37 for flat plug. The second slot 37 for flat plug is made for electrical contact with the second carbon brush, fortified according to figure 1 in the second holder 15 carbon brushes. Thus, the end plate 10 of the stator side In before winding pole coils 5, 6 on the package 2 of the stator core pre-assembled together with the switch 31 to the armature circuit. In an alternative embodiment, it is also possible the production of an end plate 10 of the stator side In already integrated with the first connecting wire 33 and integrated second connecting wire 36. This is done, for example, in the form of a stamped grid, which is in the process of injection molding is poured into the apparatus for injection molding in the manufacture of an end plate 10. In this text the tea electrical connection between the switch 31 and a stamped grid (not shown) is achieved by the insertion of the switch 31 in the receiving bracket 30 of the end plate 10 of the stator.

The figure 4 shows a top view of the end surface of the package 2 of the stator core in accordance 1 with the magnetic disk 10 on the b-side, with the wound (on the package) the first pole coil 5 and the second pole coil 6. To attach the wires of the windings of the first and second pole coils 5, 6 according to figure 3 and figure 4 three mounting plates 24 of the connecting terminal 11 is made in the form of the first weld of the hook 38, the second welded hook 39 and the third weld hook 40. Winding the first pole coil 5 has a beginning 51 of the coil and the end 52 of the coil, and the branch 53 of the coil. Similarly, the winding of the second pole coil 6 has started 61 of the coil and the end 62 of the coil, and the branch 63 of the coil. Beginning 51 of the first pole coil 5 with the end 62 of the second pole coil 6 during the winding are mounted on the first mounting hook 38 and is welded thereto. The end 52 of the first pole coil 5 and the beginning of the 61 second pole coil 6 during the winding are mounted on the second mounting hook 39 and is welded thereto. Further, the branch 53 of the first pole coil 5 and the branch 63 of the second pole coil 6 during the winding are mounted on the third mounting hook 40 and is welded thereto.

However, there are other possible schemes of connection of wires of the first pole coil 5 and the second pole coil 6. For example, in another the embodiment, the branch 63 of the second pole coil 6 is divided in such a way the second pole coil 63 will be the beginning of the second 631 coil and the second end 632 of the coil. According to this second embodiment, it is now the beginning 51 of the first pole coil 5 together with the beginning 631 of the second pole coil 6 mounted on the first mounting hook 38 and is welded thereto. Further, according to the second embodiment, the end 52 of the first pole coil 5 and the second end 632 of the second pole coil 6 mounted on the second mounting hook 39 and is welded thereto. Finally, according to the second embodiment, the start of the 61 second pole coil 6, the end 62 of the second pole coil 6 and the branch 53 of the first pole coil 5 are connected to the third weld the hook 40 and is welded thereto. It is also possible that the mounting plate 24 together with the third welded hook there and the fourth welding the hook 41. Then the branch 53 of the first pole coil 5 can be separated so that the first pole coil 5 will also be the beginning of the second coil 531 and the second end of the coil 532. So, then the beginning of the 61 second pole coil 6 and the second end 532 of the first pole coil 5 can be connected to the third weld the hook 40 and welded to it. Further, the end of the coil 62 of the second pole coil 6 and the second beginning 531 of the first pole coil 5 can then be connected to the fourth prepare the hook 41 and welded thereto. Start 51, 61 of the coils, the ends 52, 62 of the coils and branch 53, 531, 532, 63, 631, 632 coils can be combined with each other and otherwise. It is also possible alternative engine without branches 53, 63 coils. In addition, the inserts 23 with welded hooks 38, 39, 40 or 41 may be located in various positions in the receiving fasteners 22 of the connecting terminal 11.

To connect tachometer 13 on the connecting terminal 11 is made of two connecting plates 24 in the form of a first flat plug 42 and the second flat plug 43. For connection of the first connecting wire 33 of the switch 31, as already mentioned ,there is a flat connector 35. To attach the first carbon brushes of the first holder 14 carbon brushes on the connecting terminal 11 has another mounting plate 24 made in the form of a flat plug 44. In a variant of the engine without the switch 31 and the second carbon brush of the second holder 15 carbon brushes directly attached to the flat plug 35. In yet another variant of the engine, in which instead of the switch 31 by fasteners 32 has a temperature sensor (not shown), for attaching the temperature sensor to the connecting terminal 11 has two additional mounting plate 24 in the form of a first flat tiny the EPA 45 and the second flat plug 46. Here also, similarly welded to the hooks 38, 39, 40, 41, may vary the distribution of the flat-type plug 35, 42, 43, 44, 45, 46 or their position in the receiving fasteners 22 of the connecting terminal 11. In addition, we can also perform the connecting elements of the connecting terminal 11 is not in the form of flat plugs 35, 42, 43, 44, 45, 46 or mounting plates with welded hooks 38, 39, 40, 41, and in the form of mounting petals for soldering or shear pins.

The figure 5 shows an alternative execution of the end plate 10 of the stator from the side with its separate structural elements in the form above and next to the side, remote from the package 2 of the stator core. The figure 6 shows a view of the end surface of the stator end disk 10 of a stator according to figure 5 and pole coils 5, 6. Unlike the version shown in figures 1-4, shown here end plate of the stator side In made simplistic in the sense that it covers only one part of the end surface of the package 2 of the stator core in the area of one of the interpolar gaps, and that there is no supporting elements for the windings. On the outside, remote from the rotor edge of the end plate 10 of the stator side In here also formed the connecting terminal 11. The connecting terminal 11 is similar is the rule embodiment, depicted in figures 1-4, the first part 18, which is made as a single unit with magnetic disk and which has projections 19 snaps. The connecting terminal 11 also has a second part 20, on which is located the grooves 21 of the latch and through which the grooves 21 of the latches and lugs 19 of the latch is attached to the first part 18. On the second part 20 of the connecting terminal 11 has eight receiving fasteners 22 for liners 23, made of sheet metal. Each of the inserts 23 has one mounting plate 24 and a pin 25, and the mounting plate 24 and pin 25 are connected to each other by a metal crosspiece 26. Next, on the first part 18 of the connecting terminal 11 instead of welded hooks in the body of the disk and formed four chamber 64 for making them metal shear pins 65 for shear connections of the windings of the stator. To connect shear pins 65 with connecting plates 24 of the inserts 23 are provided, in addition, a metal plug contacts 66. The receiving bracket 30 to the switch 31 in the armature circuit or the temperature sensor is located on the inner facing the rotor, the edge of the end plate of the stator 10 from the side opposite the connecting terminal 11, the air gap between the package 2 of the stator core and the rotor 47. Termamyl the switch 31 or the temperature sensor similarly to the embodiment, depicted in figure 3, are connected to the mounting plates 24 of the connecting terminal 11 using sockets flat connector. Unlike the version shown in figures 1-4, in an alternative embodiment, shown in figures 5 and 6, the first part 18 of the connecting terminal 11 is missing the connector block 27 by A. Only the second part 20 of the connecting terminal 11 has a plug block 28 on the side of the Century, However, there may be other variants, i.e., for example, there is only a plug-in pads 27 side and the lack of plug-in pads from 28 or available as plug-in pads 27 side a and connector pads 28 by Century
