Function
ROBA-stop
®
-M brakes are spring applied, electromagnetic safety
brakes.
Spring applied:
In a de-energised condition, helical springs (6)
press against the armature disk (5). The rotor
(3) is held between the armature disk (5) and
the corresponding mounting surface of the
machine. The shaft is braked via the gear
hub (1).
Electromagnetic:
When the power is switched on, a magnetic
field is built up. The armature disk (5) is
attracted to the coil carrier (2) against the
spring pressure. The brake is released and
the shaft is able to rotate freely.
Safety brakes:
The brake brakes reliably and safely in the
event of power switch-off, a power failure or
an EMERGENCY STOP.
