Description
Technical field
The utility model is related to the technical fields of motor, turn stator combination punching more particularly to one kind.
Background technology
It is well known that general motor, all containing stator and rotor two parts, the stator and rotor of the prior art are mostly to use
The real heart type structure of silicon steel sheet punching press laminated forming, existing stator manufacture is relatively complicated, whole heavy, and accuracy during installation
Not high, position inaccurate, causes that motor job stability is poor, noise is larger, easily damaged, and shorten motor uses the longevity
Life, and it is serious to generate heat, and to improve heat-sinking capability, some rotors are by the way of monoblock cast, but it is easily destroyed
The Distribution of Magnetic Field of motor, causes the decline of motor overall performance, and more complicated in technique, cost also increases.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides one kind and turns stator combination punching, passes through circle
Shape array reinforces stator overall structure to the stake-fastening of multi-layer stator punching；And what rotor punching was rotated according to angular progression
Laminated structure forms the rotor with spirality channel, on the premise of motor performance is not influenced, solves rotor
Heat dissipation problem, while simplify processing technology, reduce cost, reduce weight.
Technical solution is used by the utility model：One kind turns stator combination punching, is rushed including stator punching and rotor
Piece, for the stator punching in annular shape, outer shroud four direction, which is equipped with, allows stator engaging is more firm to rise as high as the banks, rise as high as the banks with
It is round-corner transition between outer shroud circular arc, stator punching internal ring wall is equipped with 24 equally distributed stator grooves, and the stator of multilayer rushes
The close riveted composition stator of stator riveting point that piece is distributed by circular array；The rotor punching is in annular shape, and outer diameter is small
18 equally distributed rotor recesses are equipped on the inside of the internal diameter of stator punching, the outer diameter of rotor punching, rotor punching center is set
The mesoporous of ventilation and heat is useful for, the rotor punching of multilayer is according to the progressive laminated structure riveting for rotating 1.2-1.5 times of slot position to the left
Rotor is combined into, the rotating channel and bottom surface angle of rotor superposition composition are 60 °.
Further, the stator groove is equipped with opening towards the one side in stator center, groove inner wall and opening it
Between be inner bevel transition.
Further, the cross section of the rotor recesses is in ellipticity, and outside arc diameter is more than inside circular arc
Diameter.
Further, the rotor riveting point of circular array distribution is equipped between the rotor recesses and mesoporous.
In conclusion a kind of of the utility model turns stator combination punching and passes through riveting of the circular array to multi-layer stator punching
It closes and fixes, reinforce stator overall structure；And the laminated structure that rotor punching is rotated according to angular progression is formed with rotating channel
Rotor, on the premise of motor performance is not influenced, solve the heat dissipation problem of rotor, production cost is low, user
Just, assembling accurate positioning, quick, improves production efficiency.

Specific embodiment
Embodiment 1
As shown in Figure 1, Figure 3, one kind turns stator combination punching to the utility model, including stator punching 1 and rotor punching 2,
The stator punching in annular shape, outer shroud four direction be equipped with make stator engaging more firm rise as high as the banks 3, rise as high as the banks with outside
It is round-corner transition between ring circular arc, stator punching internal ring wall is equipped with 24 equally distributed stator grooves 4, the stator punching of multilayer
The 5 close riveted of stator riveting point being distributed by circular array forms stator；The rotor punching is less than in annular shape, outer diameter
The internal diameter of stator punching, the outer diameter inside of rotor punching are equipped with 18 equally distributed rotor recesses 6, and rotor punching center is equipped with
For the mesoporous 7 of ventilation and heat, the rotor punching of multilayer is according to the progressive laminated structure riveted for rotating 1.2-1.5 times of slot position to the left
Rotor is formed, the rotating channel and bottom surface angle of rotor superposition composition are 60 °.
In the present embodiment, it is recessed as shown in Fig. 2, the stator groove is equipped with opening 8 towards the one side in stator center
It is inner bevel transition between slot inner wall and opening.
In the present embodiment, as shown in figure 3, the cross section of the rotor recesses is in ellipticity, outside arc diameter
More than inside arc diameter.
In the present embodiment, as shown in figure 3, being equipped with the rotor of circular array distribution between the rotor recesses and mesoporous
Riveting point 9.
The above is only the preferable specific embodiment of the utility model, but the scope of protection of the utility model is not
This is confined to, in the technical scope that any one skilled in the art discloses in the utility model, according to this practicality
New technical solution and its utility model design are subject to equivalent substitution or change, should all cover the protection model in the utility model
Within enclosing.
