Clamping/Braking Systems HMSB Electromagnetic Rod brake

HMSB Electromagnetic Rod brake
This self locking mechanism can be utilised for emergency
braking (e.g. as an antifall device on a vertical arrangement).
This causes such a high clamping force that the magnet is no
longer able to disengage the brake.
The brake must then be moved counter to the direction of
braking so that the magnet can overcome this clamping force.
When the max aggregate load (static and dynamic loads) does
not exceed the brake's nominal force, the magnetic force can
disengage the brake without the need to move it.
The pure brake version features a conical bush that moves
relative to the housing, so the HMSB cannot be positioned to
any precision. This, however, is not a necessity for braking, i.e.
stopping within a particular braking distance.
The HMSB as a rod clamp
Applications requiring high precision positioning can use
the rod clamp version. In this version, the conical bush is
connected firmly to the housing. This also means that there is
no self boosting from the working load.
The spring presses against a freely moving hub with internal
cone that also receives the magnetic force for disengaging the
brake.
