Description
Technical field
The present invention relates to converter field, specifically a kind of plastic granulating reactor permanent magnet direct-drive system.
Background technology
China's plastic mixer system many employings DC speed regulator, direct current generator form, and belong to traditional Mechanical Driven
Device, DC speed regulator output exciting current, armature supply control direct current generator, have fault rate height, energy consumption height, motor torque
The shortcoming such as pulse bigger.Along with device for high-power power electronic and the development of motor vector control technology, vector controlled is used to become
Frequently the method that device is mainly based upon field orientation, there is bigger advantage in this structure.It is thus desirable to existing plastic stir
Machine system improves, to meet the needs of actual production.
Summary of the invention
It is an object of the invention to provide a kind of plastic granulating reactor permanent magnet direct-drive system, to solve above-mentioned background skill
The problem proposed in art.
For achieving the above object, the present invention provides following technical scheme:
A kind of plastic granulating reactor permanent magnet direct-drive system, including the permanent magnet synchronous electric being arranged on plastic granulating reactor
Machine intelligent controller, permanent magnet direct driving motor and shaft coupling, described permanent magnet direct driving motor is vertically mounted on plastics by shaft coupling and makes
The top of grain reactor, described permagnetic synchronous motor intelligent controller controls permanent magnet direct driving motor, and permanent magnetism by drive software
Direct driving motor connects input power by permagnetic synchronous motor intelligent controller.
As the further scheme of the present invention: described permanent magnet direct driving motor uses the motor of air blast cooling structure.
Compared with prior art, the invention has the beneficial effects as follows:
Using permanent magnet direct driving motor output torque big in the present invention, performance is good, non-maintaining, eliminates reductor failure rate is low, subtracts
Lack intermediate transmission part and saved energy wave, improve production efficiency；It is capable of the control efficient, energy-conservation of permanent magnet direct driving motor
System, makes permanent magnet direct driving motor have higher dynamic torque corresponding, the more stable speed of service.
Accompanying drawing explanation
Fig. 1 is the structural representation of plastic granulating reactor permanent magnet direct-drive system.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1, in the embodiment of the present invention, a kind of plastic granulating reactor permanent magnet direct-drive system, same including permanent magnetism
Step intelligent motor controller, permanent magnet direct driving motor and shaft coupling, permagnetic synchronous motor intelligent controller uses motor drive software
Control permanent magnet direct driving motor and export the power that torque is big, weak magnetic property is good, by utilizing SVPWM modulation technique to a certain extent
Improve the utilization rate of busbar voltage, reduce the content of output harmonic wave, can to electric motor short circuit, transship, the fault such as electric leakage is carried out
Protection.
Permanent magnet direct driving motor receives the run signal from controller, drags reactor machine in an optimal manner and runs, root
The current value limited according to controller carries out speed controlling automatically, runs with given speed, more than current limit below current limit
Being as the criterion with current limit and be automatically adjusted rotating speed, permanent magnet direct driving motor is also certainly with heat sinking function simultaneously, thus ensures dissipating of motor
Thermal effect, it is ensured that run well.
This working-flow is as follows: permagnetic synchronous motor intelligent controller starts and drags permanent magnet direct driving motor with the highest
Rotation speed operation, now permagnetic synchronous motor intelligent controller controlled state is weak-magnetic speed-regulating control；Due to reactor material characteristic,
In reactor, load is stepped up along with permanent magnet direct driving motor runs up, until running to the restriction operation electricity that controller is arranged
Stream；After in reactor, load increases again, controller controls motor speed reduction；Because in still, object is now liquid, rotating speed reduces
Then load reduction；Controller control motor is constantly in restriction running current size and rotating speed is gradually reduced；When in still, load reaches
To be gradually lowered to flex point back loading, now controller control motor gradually rises rotating speed.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, Er Qie
In the case of the spirit or essential attributes of the present invention, it is possible to realize the present invention in other specific forms.Therefore, no matter
From the point of view of which point, all should regard embodiment as exemplary, and be nonrestrictive, the scope of the present invention is by appended power
Profit requires rather than described above limits, it is intended that all by fall in the implication of equivalency and scope of claim
Change is included in the present invention.Should not be considered as limiting involved claim by any reference in claim.
