The Unique Advantage Of Magnetic Powder Clutch Applied To Tension Control

The magnetic powder clutch transmits torque according to the electromagnetic principle and using magnetic powder. The excitation current and the transmission torque are substantially linear. It can transmit a certain torque regardless of the slip, and has the advantages of fast response, simple structure, no pollution, no noise, no impact vibration and energy saving.

         The hollow shaft magnetic powder clutch transmits torque through the magnetic powder under the electromagnetic effect, has a linear relationship between the excitation current and the transmission torque base, and is an automatic control element with superior multi-purpose performance. When the excitation current of the hollow shaft magnetic powder clutch remains unchanged, the constant torque can be stably transmitted, and the transmitted torque is not affected by the differential slip speed between the transmission member and the driven member, that is, the static torque and the dynamic torque are not difference.

         The hollow shaft magnetic powder clutch is consistent with the working principle of the magnetic powder clutch, but the two are slightly different in structure and design. Please pay attention to the input side and the output side. The hollow shaft magnetic powder clutch is divided into the inner shell rotating hollow shaft magnetic powder clutch and There are two types of housing rotary type hollow shaft magnetic powder clutch. When the magnetic powder clutch and the clutch are used for continuous sliding of winding and unwinding, the product and life are different depending on the conditions of use.

        The hollow shaft magnetic powder clutch is usually used in conjunction with the tension detector. The tension controller automatically controls the torque of the hollow shaft magnetic powder clutch to make the tension constant. Generally, the hollow shaft magnetic powder clutch operates in a slip state, and the tension is controlled by the torque of the hollow shaft magnetic powder clutch in order to keep the tension constant. When the excitation current remains the same, 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.
