In accordance with the embodiments illustrated structure of the present invention is illustrated below.
As shown in Figure 1 to Figure 3, the stator yoke iron 1 of the universal motor of embodiments of the invention is sheared the shearing that bends up respectively and is bent up the 11a of portion, 12a and constitute by two metallic plates 11,12 with from the metallic plate 11,12.On two metallic plates 11,12, have owing to shearing bends up the shearing that forms to bend up hole 11c, 11c, 12c, 12c.This shearing bend up the 11a of portion, 12a periphery, be sandwiched between two metallic plates 11,12, disposing the winding coil 2 of the coiled annular that is around on the bobbin 21.This winding coil 2 has the function of magnet exciting coil.Bobbin 21 is made by the resin of electric insulation.And the armature 3 that is made of laminated iron core is disposed to shear and bends up between the 12a of portion, the 12a, and the rotating shaft 32 that can be supported on bearing 31,31 rotates freely for pivot.In addition, on this armature 3, be wound with armature coil 4.On this armature 3, be provided with the commutator 5 that is connected with armature coil 4.The brush 6 usefulness brush holding componentss 21 that are connected with this commutator 5 are supported.The 21a of this brush support sector also can be contained on the bobbin 21; It is fixed on the metallic plate 12 as another member.
In addition, metallic plate 11 also has the function as motor mounting plate, and its periphery is provided with two mounting ear 11b, 11b.Central part at this metallic plate 11 also embeds one of bearing 31,31 of supporting shaft 32.Metallic plate 12 is except playing a part the motor side plate, and its central part also setting-in another bearing 31, and it is equally also supporting rotating shaft 32, also has the lead-in wire 7 that is connected with winding coil 2 on the metallic plate 12 and leads to outside wire hole 12b.In addition, metallic plate 11,12 by on the side of armature 3, for electric insulations such as armature 3, commutator 5 and brush 6, be covered with insulating paper 8.Shell 13 cooperates with metallic plate 11,12, covers the periphery of winding coil 2.To bend up the 11a of portion, 12a parallel with rotating shaft 32 respectively and shear, and, form the semi-cylindrical shaped that surrounds armature 3.So two shearings bend up the 11a of portion, 12a and constitute cylinder in opposite directions.
The position of brush 6 usually bends up the 11a of portion, 12a with shearing and meets at right angles (directions X of Fig. 2), but in the present embodiment, shear to bend up the 12a of portion and contact with brush 6, thereby as shown in Figure 2, the angle [alpha] that just staggers disposes.Therefore, the commutator 5 so big angle that also staggers.
The iron core of armature 3 as shown in Figure 4, has three T shape salient pole 3a, 3a, 3a and three groove 3b, 3b, 3b.On each salient pole 3a, 3a, 3a, be wound with armature coil 4 (diagram is omitted), coil is contained among groove 3b, 3b, the 3b.
This structure is identical with the structure of the general charged brush motor rotor that is used for sound equipment, toy etc.Therefore, the winding operation of armature coil 4 is not the coiling that distributes as existing motor, but concentrates coiling, can shorten the activity duration greatly, and makes steady quality, is convenient to keep in repair.
The assembling of the universal motor of this structure at first is that brush 6 is fixed on the 21a of brush support sector of bobbin 21, perhaps also is fixed in sometimes in the brush support sector of metallic plate 12.Then, the metallic plate 12 of rigid bearing 31 is fixed on the shell 13, then, the bobbin 21 of winding coil 2 is being twined in configuration.To insert the bearing 31 that is fixed in metallic plate 12 with the rotating shaft 32 that armature 3 and commutator 5 etc. rotates again.At this moment, commutator 5 is sandwiched in wherein by brush 6.Then, rotating shaft 32 is inserted through the metallic plate 11 that setting-in bearing 31, embeds installation portion 11b, 11b in groove 13a, the 13a of shell 13, makes metallic plate 11 and shell 13 relative fixed.Again because of coiling tubular type coil as magnet exciting coil, therefore, and compare before, can form exciting coil simply, simultaneously, can be beforehand with better magnet exciting coil.And, with the shearing portion of bending up sufficient insulation is arranged.
The electrical wiring of Zu Zhuan universal motor as shown in Figure 5, is used as the winding coil 2 and armature coil 4 of magnet exciting coil like this, and through brush 6 and commutator 5, AC is connected in series to alternating voltage.In more detail, armature coil 4 is made of three prominent utmost point 3a of the iron core that is around in armature 3 respectively, three salient pole coil 4a, 4a, 4a on 3a, the 3a, and its wiring is that triangle connects.But also can connect without triangle, and use other mode of connections, for example the Y formula connects.Three wire connecting portion are connected to respectively on three commutator segment 5a, 5a forming commutator 5, the 5a.And with three commutator segment 5a, 5a, the 5a of rotating shaft 32 rotation, hand over to contact the electric current I that alternating voltage AC produces flow through winding coil 2 and armature coil 4 with two brush 6a, 6a with the parallel installation of mode that clips commutator 5.This mode of connection concrete condition as shown in Figure 6, make winding pipe 21 support brush 6a, 6a, one end 2a of winding coil 2 is connected to coil terminals 22, other end 2b is connected on the terminal of a brush 6a of brush 6, and alternating voltage AC is connected on the terminal of coil terminals 22 and another brush 6a of brush 6.This method of attachment is: the wiring between winding coil 2 and brush 6 can be given earlier lead with winding coil 2 and connect and do not need special lead-in wire, tie point also less.But concrete mode of connection also is not limited thereto, and can adopt the whole bag of tricks.
The result of this electrical wiring is, the electric current I of alternating voltage AC makes to shear and bends up the magnetic pole that the mutual excitation of the 11a of portion, 12a becomes opposite polarity, and simultaneously, three salient pole 3a, 3a of armature 3,3a also alternately be the N magnetic pole a little while, are the S magnetic pole a little while.So, under their interaction, armature 3 rotations.
According to Fig. 7 other embodiment that improve space efficiency are illustrated below.The stator yoke iron 1 of this universal motor, identical with the embodiment of front, by two metallic plates 11,12, bend up the 11a of portion, 12a with the shearing that bends up from this two metallic plates shearing respectively and constitute.But this two metallic plate 11,12 one-tenth formation semicircle, that shearing bends up the 11a of portion, 12a are different from previous embodiment, are that side direction outer circumferential side shearing from central division bends up.Then, two metallic plates 11,12 are embedded in depressed part 21a, the 21a of bobbin 21 sides.And metallic plate 11 usefulness rivets 14 grades are fixed on the circular tabular metal shell 13a of supporting rigid bearing 31 and insulating paper 8.This metal shell 13a also has the function as the motor mounting base plate.On the other hand, metallic plate 12 usefulness rivets 14 grades are fixed on the cylindrical metal shell 13b with the S of small diameter cylinder portion and the L of large diameter cylinder portion.Chimeric on the open end of the S of small diameter cylinder portion of this metal shell 13b, fixing the circular tabular metal shell 13c that block bearing 31 and insulating paper 8 are housed.
And bend up the periphery of the 11a of portion, 12a in shearing, dispose the winding coil 2 of coiled ring-type on bobbin 21.This winding coil 2 has the function of magnet exciting coil.Bobbin 21 usefulness have the resin of electrical insulation capability and make.And in the middle of shearing bent up the 11a of portion, 12a, disposing with the rotating shaft 32 that is supported on bearing 31,31 was the armature 3 that pivot rotation laminated iron core freely constitutes.Again on this armature 3 around armature coil 4.And the commutator 5 that setting is connected with armature coil 4 on this armature 3.This commutator 5 is disposed in the S of small diameter cylinder portion of metal shell 13b.Again, the brush 6 that contacts with this commutator 5 is disposed in the S of small diameter cylinder portion of metal shell 13b, and simultaneously, it also is fixed on the brush mount pad 61 on the metal shell 13b.And guide outside wire hole (not shown go out) into being connected on lead-in wire on the winding coil 2 having on the metal shell 13b.
In this example, brush 6 is installed on common position, can bends up (directions X of Fig. 2) on the rectangular direction of the 11a of portion, 12a with shearing, and commutator 5 also there is no need to stagger.And, in this example, neither adopt with bobbin 21 and support the structure of brush 6, thereby needn't axially do bobbin 21 thick.Therefore, can do the imaging small diameter cylinder S of portion little bore like that, compare with large diameter situation as the outer part of the brush 6 of the part of metal shell 13b, more favourable on arrangement space.
Use one of good embodiment though the foregoing description is the present invention, the present invention is not limited thereto, and can carry out various modification and be implemented in the scope that does not break away from main idea of the present invention.For example, shell 13 is that metallic plate 11,12 and other part constitute, but also can be and one of metallic plate 11,12 integrally formed part.In addition, winding coil 2 can not use bobbin yet behind coiling, be disposed to shear and bend up on the 11a of portion, the 12a and make curing module, still, at this moment must adopt the such insulating means of insulating paper for example 8 between winding coil 2 and the stator yoke iron 1 with adhesive and so on.
In addition, also can adopt the way of the outside moulding of resin mold, metallic plate 11 and metallic plate 12 be made an integral body with resin.At this moment, also can be the bobbin of the periphery that bends up the 11a12a of portion in shearing also with resin and synthesize one.
Shearing in the foregoing description bends up the shape of the 11a of portion, 12a, becomes rectangle during expansion, but in order to reduce the magnetic flux density that easily causes magnetically saturated main cause, also can make the bucking ladder that has tapering like that by image pattern 8.In this case, shear the width beta of the root that bends up the 11a of portion, 12a, make 180 degree to 210 degree, compare, widened significantly with about 155 degree of present embodiment by mechanical angle.And in this case, shearing bends up the 12a of portion and brush 6 contacted danger are bigger, thereby the angle [alpha] of Fig. 2 is necessary bigger.
As described above, the invention universal motor of claim 1 is by two metallic plates With shear the shearing section of bending up that bends up from this two metallic plate respectively and consist of stator yoke iron and prominent by it Go out the magnetic pole that section forms, meanwhile, the periphery that bends up section in the shearing that becomes magnetic pole is with fully Surround the ring-shaped winding coil excitation coil that this shearing bends up the form configuration of section, Thereby can make magnetic pole of the stator and magnet exciting coil with open-and-shut operation. And magnet exciting coil Be a winding coil, thereby can shorten the time of winding operation and make the magnet exciting coil quality Stablize, keep in repair easily.
Again, in the universal motor of claim 2 of the present invention, further magnet exciting coil is made the winding coil that is around in the insulating properties bobbin, thereby can simply be made magnet exciting coil, simultaneously, can give and do better magnet exciting coil earlier.And bend up portion with shearing and can fully insulate.
