Magnetic Powder Brakes and Clutches are proportional Torque devices. Application Systems manufactures Magnetic Powder Brakes and Clutches. Application Systems also manufactures eddy current adjustable dynamometer, Powder dynamometers, tension controller and load cells. Magnetic Powder Brakes and Clutches are manufactured in wide range Torque rating starting from tiny 0.3 KgM to massive 100 KgM,. It comes in self-cooled, forced cooled and water-cooled models. These devices has minimal drag torque, i.E. At zero excitation, torque is minimal and near to zero. These devices are for high torque - low power applications. It distinguishes itself by a simple construction, low weight and small-required space. Due to this advantage the clutch / brake is used for the solution of many technical problems. The Powder Brakes & Clutches contain, as their name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, from free flowing condition at no excitation to solid rock condition at full excitation.
