Why is it that the printing industry can use a small type of torque magnetic powder clutch? The printing industry uses the rewinding and unwinding work during printing, while the small torque magnetic powder clutch uses the magnetic powder under the electromagnetic effect to achieve torque transmission and wind up the normal speed. It is faster than the line speed of the material, so the magnetic powder clutch works in the slip state, and the tension is controlled by the torque of the small torque magnetic powder clutch.

In order to maintain a constant tension in the printing industry, the torque of the magnetic powder clutch must be increased or decreased according to the size of the winding diameter. The torque transmitted by the magnetic powder clutch is linear with the excitation current, so it has high precision and a wide range of control characteristics.

The tension is controlled by the torque of the small torque magnetic powder clutch in the unwinding device. As the winding diameter of the winding decreases, the braking torque must be continuously reduced, and the tension detector is used to detect the tension of the winding. The tension controller automatically controls the torque of the magnetic powder clutch, so that the tension can be made constant during printing, thereby completing high-precision printing work.

The above is about the introduction of small torque magnetic powder clutch in the printing industry. If you need to know about other types of worm gear reducer or the selection scheme, please consult !
