The use of magnetic powder brake characteristics

Magnetic powder brake can easily carry a wide range of control, is a kind of superior performance of the automatic control components. Magnetic powder brake is working medium with magnetic powder, with exciting current as control means, to achieve the purpose of control the brake or transfer torque. The output torque and excitation powder had good linear relationship between current and has nothing to do with speed or slip, and has fast response speed, simple structure, etc. 

Magnetic powder brake is based on the principle of electromagnetic and magnetic powder is used to output torque. Due to its output torque and excitation current basic into linear relationship, so as long as change the size of exciting current, can easily control the output torque. In general, within the scope of 5% to 100% rated torque, excitation current and torque proportional relationship. 

The exciting current of magnetic powder brake is small, but can large output torque, which can be easily composed of automatic control system. Moreover when the exciting current changes, and also with the synchronous response of magnetic field strength, and the response speed of the magnetic powder brake is so amazing, are widely used in packaging, printing, paper making, textile, printing and dyeing, rubber, wire, cable, metallurgy and other relevant rolling and coiling processing industry of winding tension control.
