Abstract
A kind of rotor of efficient noise-reducing, is related to motor field.In the prior art, the rotor punching slot that the high quadrupole motor in 280 centers uses is with being combined into 72/48, and the motor that the cooperation rotor punching of punching slot produces can generate certain electromagnetic noise, and the overall noise for making motor is also higher.The utility model includes the rotor punching of multiple overlappings, and the rotor punching is equipped with 62 punching slots.By the way that the punching slot of rotor punching is increased to 62, the electromagnetic sound of original motor can be substantially eliminated, while also the overall noise of motor can be made to decrease drastically.
Description
Technical field
The utility model is related to motor field more particularly to a kind of rotors of efficient noise-reducing.
Background technology
With the development of science and technology and progressive, people increasingly pay attention to working environment and the noise pollution of living environment is asked
Topic.Noise of motor has become the technical indicator of a more and more important measurement motor quality level.Noise of motor generally divides
For mechanical noise, ventilation noise and electromagnetic noise, electromagnetic noise can cause strong, ear-piercing noise to be felt, make one to feel very
It is uncomfortable.Stator punching and rotor punching are the vital parts used in motor, and the cooperation of rotor punching slot is stator punching
The electromagnetic noise that punching flute profile quantity and the punching flute profile quantity of rotor punching generate motor has a direct impact.
In the prior art, the rotor punching slot that the high quadrupole motor in 280 centers uses, which is matched somebody with somebody, is combined into 72/48, i.e. stator
72 punching slots are opened in punching, and rotor punching opens 48 punching slots, and the motor that thus punching slot cooperation rotor punching produces can generate
Certain electromagnetic noise, the overall noise for making motor are also higher.
Utility model content
The technical problems to be solved in the utility model and propose technical assignment be to prior art carry out improve with
It improves, a kind of rotor of efficient noise-reducing is provided, for the purpose of the electromagnetic noise for reducing motor.For this purpose, this practicality is new
Type takes following technical scheme.
A kind of rotor of efficient noise-reducing, the rotor are the high quadrupole motor rotor in 280 centers,
Include the rotor punching of multiple overlappings, the rotor punching is equipped with 62 punching slots.By the way that the punching slot of rotor punching is increased
62 are added to, the electromagnetic sound of original motor can be substantially eliminated, while also the overall noise of motor can be made to decrease drastically.
As further improving and supplementing to above-mentioned technical proposal, it is special that the utility model further includes following supplementary technology
Sign.
After the rotor punching superposition and aluminum component die casting one casts rotor core into aluminium.The structure of aluminium casting rotor is more firm
Gu noise is lower.
The punching slot one side is straight flange, and opposite side includes the first bevel edge being sequentially connected, the first connection side and second
Bevel edge, the second connection side, first bevel edge, the second bevel edge are oblique on the contrary, the widest part size of the first bevel edge and straight flange is small
In the second bevel edge and straight flange widest part size.
The punching slot one side is straight flange, and opposite side includes the first bevel edge being sequentially connected, the first connection side and second
Bevel edge, the second connection side, first bevel edge, the second bevel edge are oblique on the contrary, the widest part size of the first bevel edge and straight flange is small
In the second bevel edge and straight flange most narrow portion size.
Between the outer end of straight flange and the first bevel edge there is gap to form opening.
Advantageous effect：Essentially eliminate motor electromagnetic noise, at the same can also make motor overall noise have it is apparent under
Drop.

Specific embodiment
The technical solution of the utility model is described in further detail below in conjunction with Figure of description.
As shown in Figs. 1-2, a kind of rotor of efficient noise-reducing, the rotor punching 1 including multiple overlappings, rotor punching
Piece 1 is equipped with 62 punching slots 3.
In order to make noise lower, after rotor punching 1 is superimposed and 2 die casting of aluminum component one casts rotor core into aluminium.Aluminium casts rotor
Structure it is more secured, noise is lower.
By changing the stamping die of rotor punching 1, the rotor punching of 62 punching slots 3 is gone out on punching machine with silicon steel sheet
1, then a certain number of rotor punchings 1 and aluminum component 2 are cast into and are integrally formed cast-aluminum rotor on Special rotor die casting machine, it can base
The electromagnetic sound of original motor is eliminated in sheet, while also the overall noise of motor can be made to decrease drastically.
As shown in figure 3,3 one side of punching slot be straight flange 301, opposite side include be sequentially connected the first bevel edge 302,
First connection while 303 and second bevel edge 304, second connect while 305, first bevel edge 302, the second bevel edge oblique 304 are to phase
Instead, the widest part size of the first bevel edge 302 and straight flange 301 is less than the second bevel edge 304 and 301 widest part size of straight flange；Straight flange 301
Between the outer end of the first bevel edge 302 there is gap to form opening.
A kind of rotor of efficient noise-reducing shown in figure 1 above -3 is specific embodiment of the utility model,
Through embodying the utility model in essence feature and progress, can according to actual use needs, under the enlightenment of the utility model,
Carry out the equivalent modifications of shape, structure etc. to it, this programme protection domain row.
