DANGER
If the brake is operated with air gap "a"
> 1.8 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).
1)
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.
