Magnetic powder brake / clutch can transmit torque based on electromagnetic theory and the use of magnetic powder. It has the characteristics which magnetizing current and transmit torque has a linear relationship. It has advantages of fast response, simple structure, no pollution, no noise, no shock and vibration, energy-saving and so on. It is a versatile, superior performance of automatic control components. Magnetic powder brake is used to drive machinery, such as loading and brake
dynamometer. Magnetic powder clutch can also be used to buffer starting, overload protection, speed control and so on. It is widely used in unwinding and rewinding tension control in papermaking, printing, packaging, plastics, rubber, glass, textile, printing and dyeing, wire and cable, metallurgical and other machine and industrial.
