Description
Technical field
The present invention relates to motor technology field, be specifically related to a kind of asynchronous motor rotor.
Background technology
In machinery, many components turn round around fixing axle, and this kind of component making gyration is referred to as revolving meber, at motor
In be referred to as rotor.Each revolving meber can be regarded as being made up of some quality.If the structure of revolving meber is asymmetric or system
When making inaccurate, whole revolving meber will be made when rotating to produce the imbalance of centrifugal force system, thus whole machinery can be made to produce
Vibration, this vibration can cause machine work precision and reliability to reduce, the fatigue damage of part material and disgusting
Noise.All the time, in electromechanics trade, many electrical machinery plants are during making motor, and engineering department requires to pass through rotor outer circle
Processing ensures the concentricity of rotor outer circle, and general allowance is monolateral about 0.3mm.
In prior art, when designing due to threephase asynchronous machine, the power of same support does bigger and bigger, so the ferrum of design
Heart length will be more and more longer；And unshakable in one's determination long time, aluminum process is restricted, as easily produce shrinkage cavity, cast aluminium is not enough, disconnected
The defects such as aluminum；So qualification rate of cast aluminium is the highest, causes damage bigger.Rotor is the key components and parts in motor, its material,
Aluminum process controls the most well, and motor is easy for producing electromagnetic noise, electric current is unstable, rotor loss increases, temperature rise
High defect.
Therefore, for the problems referred to above, the present invention proposes a kind of new technical scheme.
Summary of the invention
It is an object of the invention to provide a kind of rational in infrastructure, rotor balancing is good, it is ensured that the service behaviour of motor, and
The asynchronous motor rotor of working effect.
The present invention is achieved through the following technical solutions:
A kind of asynchronous motor rotor, including rotating shaft, rotor core, rotor field spider and sliver, described rotor field spider center is provided with
Rotating shaft, described rotor field spider two ends are equipped with end ring, ring-type several slivers that is evenly distributed with, end ring end face between described end ring
On be all inlaid with several flabellums, be provided with rotor core between sliver and rotor field spider, sliver is evenly distributed on rotor core
Surface, between described rotor field spider and rotor core, height has ring-like collar, and between described ring-like collar and rotor core, dry has
Several ventilation slots.
Further, described rotor field spider is provided with flange, and described flange side connects balance weight, described balance weight with
Flange matches, and described balance weight side connects bolt.
Further, described balance weight has been adopted silicon steel material and has been fabricated by.
Further, described rotor core offering cell body, embedded being placed with of cell body has turned winding.
Further, if described end ring offers an air vent, air vent is through with ventilation slot.
The invention has the beneficial effects as follows: the present invention combines simply, reasonable in design, it is ensured that rotor is flat in work process
Weighing apparatus performance, and radiating effect, thus reduce motor electromagnetic noise in the course of the work, the unstability of electric current, improve
Precision in work process and reliability, and, improve the service life of motor, eliminate use hidden danger.

Rotor field spider 2 center is provided with rotating shaft 1, and rotor field spider 2 two ends are equipped with end ring 4, ring-type between end ring 4 is evenly distributed with several
Sliver 5, end ring 4 end face is all inlaid with several flabellums 3, is provided with rotor core 8, sliver 5 between sliver 5 and rotor field spider 2
Being evenly distributed on rotor core 8 upper surface, between rotor field spider 2 and rotor core 8, height has a ring-like collar 7, ring-like collar 7 with turn
Between sub-iron core 8, dry has several ventilation slots 11.
In the present embodiment, rotor field spider 2 is provided with flange, and flange side connects balance weight 10, and balance weight 10 is with convex
Edge matches, and balance weight 10 side connects bolt 9.
In the present embodiment, balance weight 10 has been adopted silicon steel material and has been fabricated by.
In the present embodiment, rotor core 8 offering cell body, embedded being placed with of cell body has turned winding.
In the present embodiment, if end ring 4 offers an air vent 6, air vent 6 is through with ventilation slot 11.
The present invention combines simply, reasonable in design, it is ensured that rotor is at the middle balance quality of work process, and heat radiation effect
Really, thus reduce motor electromagnetic noise in the course of the work, the unstability of electric current, improve the precision in work process
And reliability, and, improve the service life of motor, eliminate use hidden danger.
The foregoing is only embodiments of the invention, not thereby limit the scope of the claims of the present invention, every utilize this
Equivalent structure or equivalence flow process that bright description and accompanying drawing content are made convert, or are directly or indirectly used in other relevant skills
Art field, is the most in like manner included in the scope of patent protection of the present invention.
