The utility model proposes a kind of motors 100, are applied to food cooking machine.

In the utility model embodiment, as shown in Figure 1, the motor 100 include: field frame assembly 10, mover assembly 50 and After-poppet assembly 33；Field frame assembly 10 includes stator core 11, and stator core 11 is in the tubular of both ends open；Mover assembly 50 is worn In stator core 11, mover assembly 50 includes the commutator 57 that armature spindle 51 and fixing sleeve are set to armature spindle 51, after-poppet Assembly 33 includes at least the carbon brush component 35 of a pair of of 51 radial symmetric setting of relative rotor axis, and carbon brush component includes supporting commutator 57 carbon brush body 351, the hardness value range of carbon brush body 351 are as follows: 5HS~25HS.

Referring in particular to shown in Fig. 1, stator core 11 can be circular in cross-section or rectangular tubular, certain stator The shape of iron core 11 can also be designed according to 100 actual application environment of motor.Stator core 11 can be made of metallic zinc, And it can produce to obtain by pressing mold mode.Since zinc is that the blunt material of acoustics allows stator core 11 effectively to absorb electricity Generated noise in 100 operational process of machine.Field frame assembly 10 further include the stator that is wound on 11 inner wall of stator core around Group 13, mover assembly 50 further include the rotor core 53 that fixing sleeve is set on armature spindle 51, turn being wound on rotor core 53 Sub- winding 55 and fixing sleeve are set to the commutator 57 on armature spindle 51, commutator 57 and rotor core 53 along the axis of armature spindle 51 To arrangement.

When installing each component of motor 100, first mover assembly 50 is inserted into the stator core 11 of field frame assembly 10, together When will be wound with the stator winding 13 on the 53 face field frame assembly 10 of rotor core of rotor windings 55.At this point, mover assembly 50 In the both ends of armature spindle 51 be pierced by the opening at 11 both ends of stator core respectively, commutator 57 also protrudes from 11 end of stator core Opening.Further, by armature assembly 31 be covered on stator core 11 be not provided with commutator 57 one end opening and Make the end of armature spindle 51 through the armature assembly 31, after-poppet assembly 33 is covered on stator core 11 equipped with commutator 57 One end opening and make the other end of armature spindle 51 through the after-poppet assembly 33.And at this point, after-poppet assembly 33 It is formed with accommodating space towards field frame assembly 10 is recessed, the side wall of the accommodating space is opposite to be equipped with carbon brush component 35, commutator 57 Be placed in the accommodating space and be located at the inside of carbon brush component 35 and the carbon brush component 35 that is oppositely arranged clamped by.Specifically Ground, carbon brush component 35 include carbon brush body 351, and carbon brush body 351 supports the circumferential surface of commutator 57.

Further, since commutator 57 with armature spindle 51 when rotating, there is opposite fortune between carbon brush body 351 It is dynamic, thus carbon brush body 351 can have abrasion.In order to extend the service life of carbon brush body 351, the hardness of carbon brush body 351 It need to be maintained in relatively suitable hardness range.The hardness value model of preferred carbon brush body 351 in technical solutions of the utility model It encloses are as follows: 5HS~25HS.If the hardness of carbon brush body 351 is less than 5HS, carbon brush body 351 itself is excessively soft, leads to carbon brush body 351 with commutator 57 support and have relative motion when, carbon brush body 351 is more easier have biggish abrasion because of frictional force Phenomenon.If the hardness of carbon brush body 351 is greater than 25HS, carbon brush body 351 itself is harder, when carbon brush body 351 is come from When the frictional force of commutator 57, more sharp noise can be issued therebetween, to influence the usage experience effect of user.

Technical solutions of the utility model support commutator 57 by carbon brush body 351, so that carbon brush body 351 is connected with power supply When, opposite carbon brush body 351 can be used as the electrode of opposed polarity, and then electric current is transferred to rotor windings by commutator 57 In, it is rotated since the rotation of armature spindle 51 will drive commutator 57, opposite sliding between commutator 57 and carbon brush body 351, in turn Realize the effect of commutation.In addition, then making carbon brush in 5HS~25HS in the hardness range of the carbon brush body 351 of the utility model Ontology 351 has appropriate hardness, to both be avoided that carbon brush body 351 was excessively soft and causes biggish abrasion；It is avoided that again Carbon brush body 351 it is really up to the mark and with commutator 57 have relative motion when generate sharp noise.

In order to further increase the service life of motor 100, the outer diameter ruler of commutator 57 in technical solutions of the utility model Very little also to need to carry out appropriate adjustment, the outer diameter that commutator 57 is defined in the present embodiment is Φ, preferably 25mm≤Φ≤35mm.

If the outer diameter Φ < 25mm of commutator 57, the current density on 57 surface of commutator is larger, so that commutation Heat dissipation effect is bad after device 57 generates heat, and then influences the service life of motor 100；If the outer diameter Φ > of commutator 57 35mm, then carbon brush body 351 is larger with respect to the linear velocity of commutator 57, to aggravate the abrasion of carbon brush body 351, thus equally It will affect the service life of motor 100.

Carbon brush body 351 can also be used grease-contained carbon brush body 351 in the present embodiment, to reduce carbon brush body Frictional force between 351 and commutator 57, and then reduce the degree of wear of carbon brush body 351 and commutator 57.

Specifically, grease can be coated on the surface of carbon brush body 351, can also make grease molecules by soaking technology It penetrates into inside carbon brush body 351.When carbon brush body 351 and heat exchanger 57 just start opposite sliding, carbon brush body 351 can be sent out Heat, so that lubricant layer is precipitated to the surface of carbon brush body 351, to reduce between carbon brush body 351 and commutator 57 Frictional force reduces the degree of wear of carbon brush body 351, guarantees that motor 100 expeditiously operates.

It is understood that being precipitated to guarantee the effect that is electrically connected between carbon brush body 351 and commutator 57 to carbon brush The grease on 351 surface of ontology still has certain electric conductivity.However, to ensure that the resistivity of carbon brush body 351 is still in above-mentioned In preferable range, the weight accounting of grease is 0.2%~2% in technical solutions of the utility model.

If grease weight accounting less than 0.2%, grease to the lubricant effect between carbon brush body 351 and commutator 57 not It is enough, there is the case where excessive wear after still making carbon brush body 351 and the opposite sliding of commutator 57.When grease weight accounting When greater than 2%, grease plays biggish insulating effect to materials such as graphite inside carbon brush body 351, therefore can not make carbon completely The resistivity of brush ontology 351 is in preferable range, and then is difficult to extend the service life of motor 100.

Further, as shown in Fig. 2, in order to guarantee the stability of carbon brush body 351 and realize that carbon brush body 351 is exchanged There is appropriate elasticity effect always to device 57, carbon brush component 35 further includes the carbon brush that elastic component 352 and one end have opening Copper sheathing 353, elastic component 352 are installed in carbon brush copper sheathing 353, and one end of carbon brush body 351 is slideably contained in carbon brush copper sheathing It is supported in 353 and with elastic component 352, the other end stretches out the opening of carbon brush copper sheathing 353 and supports the outer peripheral surface of commutator 57.

Effect is supported to carbon brush body 351 by the elastic component 352 being installed in carbon brush copper sheathing 353, so that carbon brush sheet Body 351 can support commutator 57 with certain elastic force, and then guarantee to stablize between carbon brush body 351 and commutator 57 and connect Touching, and then realize good electrical connection effect therebetween.Carbon brush body 351 stretches out carbon brush copper away from one end of elastic component 352 The opening of set 353 is still ensured that in the case where carbon brush body 351 can be guaranteed with certain abrasion and is connect with the good of commutator 57 Touching.

Specifically, the shape of elastic component 352 with no restriction, as long as guarantee elastic component 352 to carbon brush body 351 have direction The elastic force of commutator 57.Such as elastic component 352 can be compressed spring, elastic component 352 is installed on carbon brush copper sheathing 353 at this time It is interior, and abutted with the bottom wall of carbon brush copper sheathing 353；Or the bottom wall of carbon brush copper sheathing 353 is convexly equipped with guide post, compressed spring can be arranged In in guide post.

Further, it is installed on after-poppet assembly 33 to guarantee that carbon brush component 35 can be stablized, carbon brush component 35 is also Including carbon brush holder 354, for smaller installation space, carbon brush holder 354 can have installing port, and carbon brush copper sheathing 353 can be inserted into carbon brush holder In 354, carbon brush component 35 is fixedly installed in after-poppet assembly 33 by carbon brush holder 354.

In actual application, the shape of carbon brush body 351 can be with no restriction.In view of conditions such as manufacturing process, The shape of preferred carbon brush body 351 can be strip or arc-shaped setting in the present embodiment.

As shown in figure 3, the carbon brush body 351 of arc can also make it relative to long straight under conditions of installation space is certain The effective length of the carbon brush body 351 of item is longer, therefore is able to extend the time of the abrasion of carbon brush body 351, and then extends motor 100 service life.

As shown in figure 4, when carbon brush body 351 is in long strip, in order to increase carbon brush body in certain installation space 351 length, the length direction of carbon brush body 351 and the axial angle of armature spindle 51 are acute angle.Carbon brush can so be made Ontology 351 can not radially extending along armature spindle 51, therefore in the timing of radially installed space one, above-mentioned mounting means can be with Increase the length of carbon brush body 351, and then the wearing- in period of carbon brush body 351 can be extended, that improves motor 100 uses the longevity Life.

As shown in figure 4, carbon brush body 351 is adapted to close to the end face of commutator 57 with the periphery wall of commutator 57, and with change It is abutted to the periphery wall of device 57.

It is in long strip in above-mentioned carbon brush body 351, and the axial angle of length direction and armature spindle 51 is the condition of acute angle Under, carbon brush body 351 is adapted to close to the end face of one end of commutator 57 with 57 periphery wall of commutator, and the periphery with commutator 57 Wall abuts, then the surface area of the end face at 351 end of carbon brush body is larger, and then increases carbon brush body 351 and commutator 57 On the one hand contact area makes have good conductive effect between carbon brush body 351 and commutator 57, on the other hand reduces Current density reduces the degree of heat at this.

With further reference to Fig. 4, one end in order to avoid carbon brush body 351 far from commutator 57 is being pacified with field frame assembly 10 It is interfered when dress, the one end of carbon brush body 351 far from commutator 57 is prolonged towards the direction away from field frame assembly 10 in the present embodiment It stretches.
