Electromagnetic clutches and brakes from jbj Techniques Limited
Fast Response. Long Life. Repeatability. The H series will always duplicate performance under identical operating conditions. SmoothOperation. The H series does not utilizemechanical friction, therefore operation is smooth at any slip speed. The torque of H series electromagnetic hysteresis clutches/brakes is independent of slip speed. Torque is directly proportionate to coil current, thus the torque of each unit can be adjusted by varying the current. Once the current is stable, the torque remains constant. The H series produces drag torque without physical contact (friction) of parts and are not subject to wear (except the normal wear of antifriction bearings). Hysteresis brake for industrial application. Torque is independent of slip speed and can be easily controlled by varying the current. Since there is no frictional contact between the magnets, the units have an extremely wide torque range and are ideally suited for testing machinery and/or application that are required to produce consistent and smooth torque over a wide range. Mounting is effortless - no adjustments tomake, no gaps to set. The H series may bemounted in the horizontal or vertical position. EasyMounting.
