Frequency converter is bridged.
Advantageous second improvement project, each motor can be attached to power supply network via frequency converter respectively according to the present invention
Place, wherein driving assembly has quantity N (N > 2) a motor and control device, wherein in order to start driving assembly control dress
All frequency converters are set while being manipulated, motor is attached at power supply network, i.e., all frequency converters is made to issue same frequency in this way
Rate however the output signal of arbitrary phase.
If expecting to have rotation speed change between the runtime of driving assembly, (it is used the driving assembly using frequency converter
It is attached at power supply network in by motor) it is especially preferred.However also revolving speed is not adjusted so that motor in this case
The consuming on regulation technology is also significantly reduced using the driving assembly according to the present invention, it means that is believed without using revolving speed
Number feedback (R ü ckf ü hrung) for it is theoretical/practical relatively.
The method for running the driving assembly is defined in the present invention.
Detailed description of the invention
Currently preferred improvement project is obtained by next.Elaborate implementation of the invention with reference to the accompanying drawings
Example, and it is without being limited thereto.Wherein:
Fig. 1 shows the driving assembly of vertical roller mill.
Fig. 2 shows an embodiment of the driving assembly of vertical roller mill according to the present invention.
Specific embodiment
The present invention relates to a kind of driving assemblies of vertical roller mill.The driving group of vertical roller mill according to the present invention
Part includes shell 10.Pressing plate 11 is supported by shell 10, it can be around the vertical rotation of pressing plate rotation axis 12 and its formation
The output section of driving assembly.Transmission device 13 is located in the housing 10 under pressing plate 11, is in rotation with pressing plate 11 and drives
In dynamic connection.Furthermore multiple motor 14 are disposed under transmission device 13 in the housing 10, via transmission device 13 with
Pressing plate 11 is in rotation drive connection.Driving assembly includes quantity N=8 motor 14 in an illustrated embodiment.However it should
Quantity is purely illustrative matter.Also it may be present less than N=8 or more than N=8 motor 14.However the quantity of motor 14 is greater than
Two, N > 2 are applicable in.N > 4 be it is preferred, N >=6 are particularly preferred.
In driving assembly according to the present invention, motor 14 all without rotational speed regulation be configured to asynchronous working, have
The squirrel cage motor of revolutional slip.According to the present invention correspondingly without using MS master-slave-driving assembly (such as this in the prior art or
In practice it is common as), but the squirrel cage motor 14 not being conditioned using revolving speed.Thus it can reduce on regulation technology
It expends.
In embodiment shown in Fig. 2 each of motor 14, i.e. revolving speed it is unadjusted, it is asynchronous working, have turn
Each of squirrel cage motor of rate can be attached at power supply network 16 via the switching device 15 that can individually manipulate respectively,
In, the switching device 15 of the embodiment of Fig. 2 is embodied as the simple switch that can be opened and closed.
These switching devices 15 are controllable based on control device 17, i.e., make in this way to start driving assembly control device
17 by being closed corresponding switching device 15, by unique motor 14 or alternatively two motor 14 are coupled simultaneously first
To at power supply network 16, wherein control device 17 is then by being closed corresponding switching device 15 successively respectively by another motor
14 are individually attached at power supply network 16, that is, until all N number of motor 14 are attached at power supply network 16.
If not needing rotation speed change under a load for example during running driving assembly, the component of Fig. 2 is (at it
In each squirrel cage motor 14 can be successively attached at power supply network 16 by the control of control device 17 by closure switch device 15)
It is especially suitable for.
It, will at least N- by correspondingly manipulating corresponding switching device 15 via control device 17 in order to start driving assembly
2 motor 14 successively and are therefore individually attached at power supply network 16, thus the starting current at driving assembly
(Anfahrstrom) it is limited.Because driving assembly is almost not subject to operational forces square (Arbeitsmoment) when starting, drive
Dynamic component accelerates on the revolving speed established according to revolutional slip.Because all motor 14, i.e. all squirrel cage motors 14 are in and hold
In long mechanical drive connection, all drive motors have about the same revolving speed according to revolutional slip.If driven starting
All squirrel cage motors 14 are attached at power supply network 16 after component, then driving assembly can be made to load.Load is herein in squirrel-cage
About its revolutional slip in the operating point (Betriebspunkt) of vertical roller mill in the range of the magnetic manufacture deviation of motor 14
It is assigned on each squirrel cage motor 14.
Rotational speed regulation in MS master-slave-driving assembly meaning is not required using driving assembly according to the present invention.
Work torque can be born in proportion at any time by all squirrel cage motors 14 in lasting mechanical drive connection.Asynchronous
Revolutional slip is improved as higher operation torque and is similarly resulted in power as provided by it at all squirrel cage motors 14
Raising.
It is distinguished with the embodiment of Fig. 2, it is also possible to will individual unshowned frequency converter instead of simple switching device 15
It is associated with each squirrel cage motor 14.Control device 17 manipulates all frequency converters simultaneously in this case, will be configured to mouse
The motor 14 of cage motor is attached to jointly at power supply network 16, i.e., makes in this way and then all frequency converters issue same frequencies hastily
And the output signal of arbitrary phase is for manipulating corresponding motor 14.It is correspondingly logical in order to start driving assembly in this case
It crosses while manipulating frequency converter associated there and all motor 14 are attached to jointly at power supply network 16, wherein frequency converter hair
Identical frequency however the output signal of out of phase out.
If driving assembly should change its revolving speed in operation, with such frequency converter, (it is equally without revolving speed tune
Save land work) driving assembly be advantageous.So in this case frequency converter can the manipulation of controlled device 17 at making its that
This issues the frequency that band changes and the again control signal of arbitrary phase, so to cause revolving speed to become at driving assembly
Change.In order not to the rotation speed change being conditioned, control device 17 correspondingly issues frequency-theoretical value for all frequency converters 15, so
And the feedback in the not firm meaning adjusted now according to the present invention.
