DANGER
If the brake is operated with air gap "a" > 1.0 mm, it becomes a safety risk as the braking effect is no longer given
because the armature disk (2) lies again the hand release (6).
5)
The thermal load for a brake cannot be stated. Most of the brake energy is transferred onto the brake disk.
The thermal load capability is dependent on the heat dissipation capacities of the brake disk.
