Embodiment
Fig. 1 shows motor 1(motor) schematic cross sectional view, described motor has pole shoe 2, is provided with a plurality of stator poles on described pole shoe.In the inside of pole shoe 2, be provided with inner fovea part, at described inner fovea part rotor 6, be rotatably arranged on axle.Stator poles is so arranged on pole shoe 2, makes direction that this stator poles the points to inner fovea part direction of rotor 6 in other words.
Stator poles is configured to permanent magnet-stator poles 4 and is configured to not be provided with the series connection utmost point 5 of permanent magnet 3.Pole shoe 2 preferably consists of permeability magnetic material, to so connect (magnetic connection) by the magnetic between pole shoe 2 structure permanent magnet-stator poles 4 and the series connection utmost point 5.Yet the quantity N of stator poles 4,5 is not limited to four, but quantity that can stator poles 4,5 is set to any one even number.
Rotor 6 has the armature 7 of magnetic conduction, and described armature has a plurality of rotor tooths 8, has ten rotor tooths in shown embodiment, described rotor tooth respectively by one or more rotor coil 10 of rotor winding around.The axle of rotor 6 and armature 7 axially stagger and are bearing the commutator with a plurality of commutator segments 11, and described commutator segment is equivalent to the quantity of rotor tooth 8 substantially, are ten in shown embodiment.Commutator segment 11 by two, three or more brush 12 in other words a plurality of brushes to contact.The rotor coil of commutator segment 11 and rotor winding is with the form of loop winding/be connected with the rotor coil of the rotor winding of loop winding configuration, that is to say that each commutator segment 11 is connected by one or more rotor coil commutator segment 11 adjacent with two respectively.
In Fig. 2, schematically showing rotor coil 10 is arranged on two adjacent commutator segments 11.Although in shown embodiment commutator and rotor tooth 8 arrange conglobate, yet in this case be more convenient to understand and select, with straight line, commutator segment 11, brush 12, rotor tooth 8 and rotor coil 10 are shown.In shown example, rotor tooth 1 is adjacent with rotor tooth 10 specifically, and commutator segment 1 is adjacent with commutator segment 10.
In shown motor 1, be provided with two brushes 12 that brush is right, by described brush to applying respectively supply voltage, to be the energising of 10 minutes other rotor coil groups of stator coil.The fixing location, position of the brush 12 by brush, when it is electrified stream, the position that is electrified the rotor coil 10 of stream is determined in the residing region of rotor coil 10 in other words.This is owing to conventionally symmetrically selecting winding diagram, thereby makes at rotor, after one or more movement step of the width of commutator segment 11, to exist respectively similar energising situation.
When second brush of the first brush contrast by brush centering by brush centering is when making more rotor coil 10 energising on the rotor tooth 8 towards the series connection utmost point 5 location, when motor 1 running, the right brush 12 of the first brush suffers the brush 12 more serious wearing and tearing more right than the second brush based on it compared with high inductance.
In addition, commutator segment 11 is electrically connected to mutually in appropriate mode, thereby make when corresponding brush is when inswept thereon, two adjacent commutator segments 11 make to be short-circuited by the rotor coil group one of them energising, stator coil 10 of two commutator segments 11 respectively.Can make thus the rotor coil group of stator coil 10 be short-circuited before reversal, thereby make to apply supply voltage for the voltage of inducting in rotor coil group.Due to the rotor coil group that makes stator coil 10 by the fixing layout of brush 12 (mode) always at same position by corresponding brush to being short-circuited, the inductance that depends on position based on rotor coil group forms by spark or analog causes the difference of brush 12 to wear and tear equally.
In order to reduce, get rid of in other words this effect, setting now has the rotor coil group of identical inductances switches on by brush to being respectively, and makes to have in other words the rotor coil group short circuit of identical inductances by single brush.At this, so select the position of the rotor coil 10 of rotor coil group, make its overall the same ground of wrapped rotor tooth 8, for example that is to say and attach troops to a unit in permanent magnet-stator poles 4 and the series connection utmost point 5 with identical respectively quantity.By this way, the identical overall inductance of all brushes 12 contact, thus make the wearing and tearing of brush 12 substantially the same, and thereby the change in resistance that there will not be significantly when by brush 12 contact commutator segment 11, produce due to wearing and tearing.
Because permanent magnet-stator poles 4 and the series connection utmost point 5 have different magnetic poles, by attaching troops to a unit, in the winding direction of the rotor coil of described one or more series connection utmost point, be arranged to contrary with the winding direction of attaching troops to a unit in the rotor coil of described one or more permanent magnet-stator poles.Thus, when common energising, generate as magnetic field exciting magnet magnetic field, that there is different directions.
In shown embodiment, the rotor coil 10 of rotor coil group is connected mutually.For two rotor coils 10 that surpass of rotor coil group, also can consider the mode that the rotor coil simultaneously contacting by commutator is carried out to parallel connection or adopts series and parallel to combine.
In addition the rotor coil 10 of Odd number can be set for each rotor coil group, wherein must guarantee, by attaching troops to a unit in the rotor coil 10 of the series connection utmost point 5 and the overall inductance major part that draws in the interconnection of the rotor coil 10 of permanent magnet-stator poles 4 of attaching troops to a unit produces in the rotor coil 10 of permanent magnet-stator poles 4 by attaching troops to a unit in the rotor coil 10 of the series connection utmost point 5 and attaching troops to a unit.When rotor is implemented the motion around stator poles certain distance, thereby attach troops to a unit before making, in the rotor coil 10 of the series connection utmost point 4, attach troops to a unit now in permanent magnet-stator poles 4 and attach troops to a unit before and attach troops to a unit now in the series connection utmost point 5 in the rotor coil 10 of permanent magnet-stator poles 4, under common situation, should not occur that inductance changes.If identical rotor coil device after rotor continues motion by other brush to contact, rotor coil 10 is attached troops to a unit contrary in the attachment relationship of minute other stator poles.
Preferably, the first rotor coil of the rotor coil group of the rotor coil of common contact and the second rotor coil so stagger and are arranged on rotor, make this first rotor coil and the second rotor coil be equivalent to the to connect permanent magnet-stator poles 4 of the utmost point 5 and stator apparatus, the deviation between especially adjacent permanent magnet-stator poles 4.In the above-mentioned stator apparatus with four stator poles, deviation is equivalent to 90 °.Under common situation, deviation is equivalent to 360 °/N, wherein the N total number of stator poles of utmost point device that is equivalent to connect.Conventionally deviation rotor coil group, that attach troops to a unit between the rotor coil of dissimilar stator poles can be expressed as:
(2k+1) * 360 °/N, k=0 wherein, 1 ..., N/2-1.
In Fig. 3, for ten dipolar rotors, schematically show by one of them brush the series connection of the rotor coil 10 that can contact is schemed.By brush pair, by series connection, be rotor coil 10 energisings of connecting, the second rotor coil that wherein the first rotor coil in rotor coil 10 is attached troops to a unit in one of them series connection utmost point 5 and rotor coil 10 is attached troops to a unit in the permanent magnet-stator poles 4 being adjacent.Draw thus the series inductance that is equivalent to different single inductance sums.
Another brush rotor coil 10, by brush centering is correspondingly arranged the rotor coil group of contact.By this arrangement of rotor coil 10, when rotor 6 continues rotation, series connection portion contacts by the right brush 12 of another brush, wherein the first rotor coil 10 is attached troops to a unit and is attached troops to a unit in the series connection utmost point 5 in permanent magnet-stator poles 4 and the second rotor coil 10 subsequently, that is to say that attachment relationship is contrary.At this, the overall inductance of the series connection portion of rotor coil 10 remains unchanged.By this way, in commutation, time by brush, can apply the rotor coil only with identical inductances, thereby make the wearing and tearing that there will not be brush 12 inhomogeneous.
If the quantity M of the rotor tooth 8 of rotor 6 do not allow the rotor coil arranged in rotor coil group, be the deviation of 360 °/N, also can select a deviation that deviates from slightly this, for example such for thering is the situation of ten Polar armatures of rotor of four utmost point stators of motor of Fig. 1 in Fig. 4 and Fig. 5.In above-mentioned situation, the deviation between rotor coil N/M that calculate, rotor coil group is equivalent to 2.5 rotor tooths/rotor.
If the quantity M of rotor tooth/rotor can not be divided exactly by the quantity N of stator poles, wire casing spacing is necessary, and wherein the coil-span of rotor coil of series connection is equivalent to be greater than 360 °/N(and sees Fig. 4) or be less than 360 °/N(and see Fig. 5).The in the situation that of ten rotor poles, can add 180 °/M or 90 ° of pitch arrangement rotor coils that deduct 180 °/M with 90 °.Yet expectation, together comprises accurately, is the deviation of (2k+1) * 360 °/N around a rotor or around the rotor coil that surpasses a rotor tooth.
Figure 6 illustrates an embodiment, the difference of the embodiment of described embodiment and Fig. 3 is, armature 7, commutator shaft is to the electrical connection of implementing in a relative side between the rotor coil 10 of rotor coil group.Wherein also show, the number of turn of the first rotor coil and the second rotor coil 10 can be different.
As shown in Figure 7, also can be provided for the different winding spacing of the rotor coil 10 of described two series connection, that is to say, the rotor coil 10 of rotor coil group can be around rotor or the rotor tooth 8 of varying number.
