Hysteresis brake / electromagnetic
Min.: 0.001 Nm (0 ft.lb)
Max.: 15.8 Nm (11.65 ft.lb)
Magnet assemblies (outer discs) surround our hysteresis assembly (center disc). When like poles face each other, they produce maximum magnetic saturation of the hysteresis disc, forcing lines of flux to travel circumferentially through the hysteresis disc. This produces maximum torque. When opposite poles face each other, they produce minimum saturation of the hysteresis disc. The lines of flux travel right through the hysteresis disc. Combinations of adjustment angles between these two extremes gives infinite adjustability. Because there are no contacting surfaces, the setting can be maintained indefinitely.
Advantages of permanent magnet hysteresis brakes
Built in ball bearings enable the units to carry sufficient load on the shaft
Shaft length and diameter can be manufactured exactly as per customers requirements
Precise adjustments of torque care for best repeatability of torque
Precise ground strong enough magnets care for friction-free movement and long lifetime.
