FAULHABER brakes are designed as holding brakes (not suitable for braking).
The brakes are constructed as permanent-magnet, single-surface brakes for direct current in which the braking effect is generated by a permanent magnetic field. They function as an electromagnetically open system and, thus, act in the switched-off, de-energized state. To neutralize the braking effect, the permanent magnetic field is countered by an opposing electromagnetic field. The FAULHABER brakes are flanged to the motor and are used as a motor-brake combination.
For applications in which the brakes are used for limiting or reducing the speed of motors that are in operation, i.e., so called dynamic brakes, there are a number of other versions, such as magnetic powder brakes, eddy current brakes or centrifugal brakes.
