The division of the brake circuits is done using a two-part armature disk with the associated compression
springs and electromagnetic coils. Each brake circuit can be operated individually due to the separate sup-
ply lines for each stator and armature plate (siehe ).
Each brake circuit has a micro-switch which monitors the switching state of the spring-applied brake. Us-
ing the associated switching device, the supply voltage (AC voltage) is rectified and, when the brake is re-
leased, lowered after a short period of time. This results in a reduction of the average electrical power of
the brake.
The BFK464 spring-applied brake (with the high rated torque for the respective size) is designed for a
maximum duty cycle of 60% with holding current reduction. The brakes with the lower rated torques are
suitable for a maximum 60% duty cycle with no holding current reduction. The permissible operating fre-
quency for both versions in each size is 180 1/h (with a short-term maximum of 240 1/h).
