The magnetic powder brake is based on the electromagnetic principle utilizing the magnetic powder transferring torque. It has the characteristics of the substantial linear relationship between the exciting current and the transfer torque. Independent of slip, a certain torque can be transmitted, which has the advantages of fast response speed, simple structure, low noise, no impact vibration, energy saving.
It has been widely used in paper, printing, plastic, rubber, textile, dyeing, wire and cable, metallurgy industries and other unwinding and winding tension control in the coiled processing industry.
