Do you know what the applicable range and performance of torque motors are when winding?Here isBriefly understand the application range and performance of torque motor in fabric winding. In the production process of various kinds of fabrics, the finished products of this process should be rolled into tubes or disks for use in the next process; Dc motor or magnetic powder clutch are commonly used in winding systems. However, due to the complex structure of DC motor and large maintenance, the magnetic powder clutch has some problems such as poor slip and large power consumption.
In recent years, based on the development of frequency conversion control technology,Ac torque motorIt has been widely used in textile machine control. Its mechanical properties are consistent with the winding properties, and it has the advantages of simple control, low cost and reliable operation.
If the above figure shows the open-loop mode of system operation, thenAc torque motorThe mechanical characteristics of stator voltage regulation are shown in the figure below1,2,jAs shown in the curve, the corresponding stator voltage is U11>U12>U1j;a,a1,aNandb,b1,bNRespectively expressed as winding mechanical characteristics andAc torque motorMechanical characteristics of pressure regulation (1,2,j) of the intersection point.
