Technical field
The utility model belongs to twin rollers equipment technical field, particularly a kind of permanent magnet direct-drive system of high pressure roller mill equipment
System.
Background technology
Traditional uses asynchronous machine, universal joint shaft to roller apparatus, such as high pressure roller mill, double-roll crusher transmission system
Device, retarder impart power to roller center rod and then drive equipment operation, and this kind of drive transmission link is more, structure
Complexity, efficiency is low, energy consumption is big, two bench roller cylinder rotating speeds are asynchronous and then affect the whole efficiency of entire dynamical system.This transmission
Mode mechanical efficiency is generally 0.6 or so, and capacity usage ratio is low, and the energy strategy of existing energy-saving and emission-reduction is not inconsistent with China.Together
When, daily maintenance and replacement to easily worn parts such as retarders is more frequent, has not only affected the working efficiency of equipment, but also cause
The increase of maintenance cost.
Utility model content
The purpose of this utility model is to provide a kind of high pressure roller mill permanent magnet direct-drive system, and frequency conversion permanent magnet synchronous motor uses
Permanent-magnet material excitation realizes the transmission of low speed high torque power.
To solve the above-mentioned problems, the technical solution of the utility model is such：A kind of high pressure roller mill permanent magnet direct-drive system
System, including high pressure roller mill equipment, is characterized in that：The permanent magnet direct-drive system has further included permanent magnet direct-drive variable-frequency motor and system
Switch board, permanent magnet direct-drive variable-frequency motor to there is two same specification magnetoes, pacify respectively by two permanent magnet direct-drive variable-frequency motor tail portions
Encoder is filled, encoder is connected with system control cabinet；High pressure roller mill equipment is internally provided with roller, permanent magnet direct-drive variable-frequency motor
Main shaft directly passes through flanged joint with the axis of roller.
Compared with prior art, the advantages of the utility model and advantageous effect is：It, can be straight using inverter control motor
Connect driving load, have compact-sized, detent torque is big, it is efficient, operate steadily, reliability is high, noise is low, easy for installation etc.
Advantage is realized non-maintaining substantially.Using inverter supply, have that speed adjustable range is wide, operational efficiency is high, soft start, soft stop, soft
Many advantages, such as impact.In addition, using the straight drive system of frequency conversion permanent magnet by traditional " asynchronous machine+reduction gear box+load "
Drive mode be reduced to the direct driving mode of " magneto+load ", this type of drive across the epoch changes, greatly
The system improved reliability, reduce a large amount of mechanical loss and arrangement space during system intermediate transmission, significantly
Reduce maintenance workload, increase the effective time.

Flanged joint.
Further, permanent magnet direct-drive system directly drives variable-frequency motor using low speed large torque moment permanent-magnet.
Further, encoder data feedback is connected in same switch board, carries out being uniformly controlled speed governing.
Embodiment：The structure diagram of Fig. 2 this practicality high pressure roller mill transmission systems, as shown in the figure, permanent magnet direct-drive system packet
Include permanent magnet direct-drive frequency conversion host 5, switch board 6.In installation, magneto main shaft directly passes through method with roller axis
Orchid connection, and then roller is directly driven, then further according to the speed feedback of two rollers, permanent magnet direct-drive frequency conversion host is adjusted in real time
5 rotating speed realizes the quick response of motor running parameter and accurate control.Permanent magnet direct-drive variable-frequency motor directly drives roller,
Motor speed is less than 50r/min, and frequency is less than power frequency 50Hz.
