MAGNETIC POWDER BRAKE
Magnetic powder brake can transmit torque based on electromagnetic theory and the use of magnetic powder. It has advantages of fast response, simple, structure, no pollution, no noise, no shock and vibration, energy-saving. It is a versatile, superior performance of automatic control components. Magnetic brake an also be used to buffer starting, overload protection, speed control.
MAGNETIC POWDER CLUTCH
magnetic powder clutch is a special type of electromagnetic clutch which does not use friction plates. Instead, it uses a fine powder of magnetically susceptible material (typically stainless steel) to mechanically link an otherwise free wheeling disc attached to one shaft, to a rotor attached to the other shaft. When a magnetic field is applied to the powder, it forms chains connecting the disc and rotor. The strength of the chains depends on the strength of the magnetic field. We use the finest materials available for magnetic components to yield high friction indexes, as well as premium non-asbestos linings to improve response time and extend working life.
AUTOMATIC CONSTANT TENSION CONTROLLER
SD-B automatic tension controller is mainly composed of tension detector, high precision A/D, D/A converter and high performance single chip microcomputer. The automatic constant tension controller is based on the tension detector measuring the tension of the coil material and comparing with the set target tension, and automatically adjusting the D/A output by the PID calculation of the single chip microcomputer to change the magnetic current of the magnetic powder clutch or the brake or the servo motor. The torque is used to achieve the constant tension of the coil material, and can be widely used in various occasions where the tension is precisely measured and controlled, and has flexibility and wide applicability.
