The motor has simple structure, is economical and practical, and can ensure the axiality of the stator and rotor of the motor through the clamping connection between the end cover and the stator, and improve the service life.
Description
Technical field
The utility model relates to a kind of motor, relates in particular to a kind of electric motor end cap.
Background technology
Motor is an electronic product common in industrial production and the daily life, and in electric machine structure, stator, rotor, end cap are the three big parts of forming motor.And end cap can be divided into: cast iron end cap, aluminium die casting end cap, thin plate stretching end cap or the like form.And aluminium die casting end cap is current mode relatively more commonly used.Existing end cap substantially all is to have a monolithic case, and shell is provided with some through holes then.Owing to adopt monoblock cast, make the end cap easy deformation, when end cover body was connected with bearing pedestal, concentricity can not get assurance, and radiating effect is poor, and temperature rise is higher, and the use aluminum is more, and cost is higher relatively.
The utility model content
The technical problems to be solved in the utility model is: the motor that provide a kind of simple in structure, economical and practical, heat dispersion is high.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of motor, have at least the end cap at machine shaft, rotor, stator, fan blade and stator two ends to form, be bolted to connection between described end cap and the stator, at least be provided with 4 projectioies on the described end cap, this projection is uniformly distributed on the end cap, described projection and described stator engagement connection.
According to another embodiment of the present utility model, motor comprises that further described end cap comprises end plate, plurality of fixed seat and a bearing chamber, described bearing chamber is positioned at the end plate center, connect by circumferential reinforcement between the described holder, be connected described end plate, fixing and bearing chamber is one-body molded between described end plate and the holder by shaft orientation reinforcing rib.
According to another embodiment of the present utility model, motor comprises that further described electric motor end cap comprises the rear end cap that front end housing is connected with fan blade, and the end plate of described rear end cap is Openworks shape.
According to another embodiment of the present utility model, motor comprises that further described end cap is one-body molded by die casting.
According to another embodiment of the present utility model, motor comprises that further described end cap adopts alloy aluminum to make.
According to another embodiment of the present utility model, motor comprises that further described holder is provided with axially extending bore.
The utility model has solved the defective that exists in the background technology, can guarantee the axiality of the stator and the rotor of motor by the engagement connection of end cap and stator, improves the useful life of motor, the utility model is simple in structure, economic and practical, adopt the structure of full open model to make the perfect heat-dissipating of motor, save cost, the production efficiency height, structural strength increases, and has reduced vibration, has reduced noise, end cap weight has reduced by 1/3, the getting a promotion of the processing performance of end cap.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the explosive view of Fig. 1;
Wherein: 1, motor shaft, 2, rotor, 3, stator, 4, fan blade, 5, end cap, 51, end plate, 52, holder, 53, bearing chamber, 54, circumferential reinforcement, 55, shaft orientation reinforcing rib, 521, axially extending bore, 6, bolt, 7, projection.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Fig. 1-2, a kind of motor, have at least the end cap 5 at motor shaft 1, rotor 2, stator 3, fan blade 4 and stator 3 two ends to form, fixedly connected by bolt 6 between described end cap 5 and the stator 3, at least be provided with 4 projectioies 7 on the described end cap 5, this projection 7 is uniformly distributed on the end cap 5, described protruding 7 with described stator 3 engagement connections.End cap 5 comprises end plate 51, plurality of fixed seat 52 and a bearing chamber 53, described bearing chamber 53 is positioned at end plate 51 centers, connect by circumferential reinforcement 54 between the described holder 52, be connected by shaft orientation reinforcing rib 55 between described end plate 51 and the holder 52, described end plate 51, holder 52 and bearing chamber 53 are one-body molded.Wherein, electric motor end cap 5 comprises the rear end cap that front end housing is connected with fan blade 4, and the end plate 51 of described rear end cap is Openworks shape.
Because end cap 5 adopts above-mentioned setting, can guarantee the axiality of stator 3 with the rotor 2 of motor by the end cap 5 and the engagement connection of stator 3, improve the useful life of motor, and the structure that adopts full open model makes the perfect heat-dissipating of motor, end cap 5 weight have reduced by 1/3, the getting a promotion of the processing performance of end cap 5, and the structural strength of end cap 5 increases, reduce vibration, reduced noise.
In addition, in order to improve the processing performance of end cap 5, the preferred end cap of the utility model 5 is one-body molded by die casting.And the preferred end cap 5 of the utility model adopts alloy aluminum to make, thereby has further alleviated motor weight.
Fixing with stator 3 for the ease of end cap 5, the preferred holder 52 of the utility model is provided with axially extending bore 521.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
