Specific embodiment

The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model Limitation.

Below with reference to Fig. 1-Fig. 4 description according to the rotor 100 of the utility model embodiment.

Rotor 100 according to the utility model embodiment includes: shaft 1, rotor core 2 and commutator 4.

Rotor core 2 is installed on outside shaft 1, has rotor windings 3 on rotor core 2, and rotor core 2 is nested in shaft 1 Outside, that is to say, that rotor core 2 can be set in the outside of shaft 1.There is rotor windings 3, rotor core 2 on rotor core 2 On could be formed with multiple teeth portion, as a result, convenient on rotor core 2 coiling formed rotor windings 3.The enamel-cover of rotor windings 3 The core of line 31 includes aluminium, for example the enameled wire 31 of rotor windings 3 includes thread core of aluminum or copper clad aluminum core.The quantity of enameled wire 31 It is one or more.

Commutator 4 is spaced apart with rotor core 2, can reserve predetermined space in this way, is convenient for the coiling on rotor core 2. Commutator 4 includes insulation division 41 and commutator segment 42.Insulation division 41 is installed on outside shaft 1, and insulation division 41 is nested in outside shaft 1, absolutely Edge 41 can be bakelite.

Commutator segment 42 is set on insulation division 41, commutator segment 42 be it is made of copper, one end of commutator segment 42 is equipped with hook portion 43, hook portion 43 towards the surface of shaft 1 and the surface away from shaft 1 of commutator segment 42 are equipped with and help layer, hook portion 43 away to shaft 1 surface is equipped with and helps layer.Help layer that can be plated on 42 surface of commutator segment, helping layer is tin etc..The enameled wire 31 of rotor windings 3 It is connected with the surface towards shaft 1 of hook portion 43 and forms current path.

It is understood that due to aluminium enamel-covered wire density be lower than copper enameled wire, 100 light weight of same performance rotor, 100 computing ballance correction of rotor reduces, and unbalancing value and rotor oscillation noise is effectively reduced.

Since the upright weldering property of copper aluminium material is poor, by 42 tin plating technique of commutator segment, as the intermediate medium of copper-tin soldering, not only Solves the problems, such as copper aluminium welding, while tin solves the problems, such as that the copper aluminium tie point property led is poor as intermediate medium.

According to the rotor 100 of the utility model embodiment, the lightweight of rotor 100 may be implemented, effectively drop Low unbalancing value and rotor oscillation noise, and rotor windings 3 and commutator segment 42 are connected firmly.

In some embodiments, sealant is coated with outside the solder joint of the enameled wire 31 of hook portion 43 and rotor windings 3.It can manage Solution, since aluminum steel is easier to aoxidize, needs a large amount of insulating cement when being sealed isolation air since rotor uses aluminum steel Water.After commutator segment 42 and enameled wire 31 weld, in 42 solder joint surrounding coating glue of commutator segment, hot setting is carried out, forms sealing Layer, butt welding point are protected.

In some embodiments, with reference to Fig. 3, the surface towards shaft 1 of hook portion 43 is equipped with groove, the paint of rotor windings 3 Envelope curve 31 protrudes into groove.The enameled wire 31 of rotor windings 3 can be connect with commutator segment 42 by the way of Pressure Welding, be arranged recessed Slot can reduce the deflection of enameled wire 31.The depth of groove can be greater than the radius of the core of enameled wire 31, the depth of groove Less than the diameter of the core of enameled wire 31, such enameled wire 31 can closely be bonded connected with hook portion 43 and commutator segment 42.It is recessed Slot is located at the one end of hook portion 43 being connected with commutator segment 42, to reserve enough weld lengths for hook portion 43 and commutator segment 42.

In some embodiments, rotor windings 3 are set as the spooling equipment in coiling and peel off for being connected with hook portion 43 The insulating layer of one section of enameled wire 31, and hook portion 43 and commutator segment 42 pass through pressure welding.It is understood that armature rotor around When line, the enameled wire 31 in commutator segment 42 and hook portion 43 realizes that spooling equipment peels off 31 surface insulation layer of enameled wire automatically, passes through Pressure head 100 avoids the local pressure welding that position of the enameled wire 31 in hook portion 43 carries out hook portion 43 and commutator segment 42, guarantees hook Portion 43 and 42 solder bond force request of commutator segment.In this way, can effectively ensure that electrically connecting for enameled wire 31 and commutator segment 42, protect simultaneously Card 42 electroplating surfaces with tin layer of commutator segment is not destroyed.

Certainly, for electrically connecting for enamel insulated aluminium wire and tin plating commutator 4, the enamel-cover in commutator segment 42 and hook portion 43 is effectively ensured Line 31 needs to remove insulating layer, while guaranteeing that 42 electroplating surfaces with tin layer of commutator segment is not destroyed, by the armature group of coiling enameled wire 31 Part is put into welding fixture, adjusts welding equipment parameter, guarantees suitable welding heat, realizes that 31 surface of enameled wire is exhausted in hook portion 43 While edge layer is effectively peeled off, while guaranteeing the validity of 42 tin coating of commutator segment.

The invention also discloses a kind of motors.

The motor of the utility model embodiment has the rotor 100 of any of the above-described kind of embodiment, by motor The rotor 100 of above-described embodiment is set, the service performance for improving motor is conducive to.

The invention also discloses a kind of compressors.

The compressor of the utility model embodiment has the motor and compression mechanical part of any of the above-described kind of embodiment, and motor is used In driving compression mechanical part rotation.By the way that the motor of above-described embodiment is arranged on the compressor, be conducive to improve making for compressor Use performance.
