Magnetic Powder Clutch Performance And Application Characteristics

The magnetic powder clutch uses the magnetic powder under the electromagnetic effect to transmit torque. It has the advantages of linear relationship between excitation current and transmission torque, fast response, simple structure, no impact, no vibration, no noise, no pollution, etc. The multi-purpose high-performance automatic control component is widely used in the loading and braking of machinery in various industries and the tension control of winding and unwinding in the winding system.

Unwinding: The tension of unwinding is controlled by the braking torque of the magnetic powder clutch in the unwinding device. As the winding diameter of the winding is continuously reduced, the braking torque must be continuously reduced. The tension detector is used in the figure. The tension of the winding is detected, and the torque of the magnetic powder clutch is automatically controlled by the tension controller to make the tension constant.
Winding: The winding speed is normal faster than the material's linear speed, so the magnetic powder clutch works in the slip state, and the tension is controlled by the torque of the magnetic powder clutch. In order to keep the tension constant, it must be increased or decreased according to the size of the winding diameter. The torque of the magnetic powder clutch.

Features:
The excitation current is linear with the torque: the torque of the magnetic powder clutch is basically linear with the magnitude of the excitation current. The magnitude of the control torque can be arbitrarily adjusted by changing the magnitude of the excitation current.
Stable torque characteristics: When the excitation current remains constant, the torque will be transmitted steadily without being affected by the change in speed. This feature is used in tension control, and only needs to adjust the excitation current to accurately control the torque, so as to achieve the purpose of controlling the tension.
Applications: Paper industry, production of adhesive tape, wire and cable manufacturing, packaging industry, paper processing, printing industry, film, film industry, textile industry, metal foil processing, rubber industry, fiber industry, gasoline engine, diesel engine loading and running Testing, loading in various tests, leather industry, fiber manufacturing, and other related coiling and processing industries.
