Principle and application of magnetic powder clutch and magnetic powder brake

Magnetic powder clutches and magnetic powder brakes transmit torque based on electromagnetic principles and use magnetic powder. The transmitted torque and the exciting current are basically linear. Therefore, as long as the magnitude of the magnetizing current is changed, the magnitude of the torque can be easily controlled. Under normal circumstances, within the range of 5% to 100% of the rated torque, the magnetizing current of a large-scale wheel axle flaw detector is proportional to the torque it transmits. Proportional linear relationship.
Stable slip torque When the exciting current remains unchanged, the torque transmitted by the magnetic powder clutch and magnetic powder brake is not affected by the differential speed (slip speed) between the transmission and driven parts, that is, the static torque and the dynamic torque have no The difference. Therefore, a constant torque can be transmitted stably. If this feature is used for tension control, users only need to adjust the magnitude of the exciting current to accurately control and communicate the required torque.What is tourmaline sweat steam room, large valve flaw detector, so that the control volume can be easily and effectively reached. Purpose of material tension.
Application range of magnetic powder clutchBecause of the above characteristics of magnetic powder clutch and magnetic powder brake , it has been widely used in papermaking, printing, plastics, rubber, textile, printing and dyeing, wire and cable, metallurgy and other related coil processing industries Tension control. In addition, magnetic powder clutches can also be used for cushioning starting, overload protection, speed regulation, etc. Magnetic powder brakes are also often used for dynamometer loading and braking of transmission machinery.
