INTORQ | BA 14.0177 | 04/2016
13
The INTORQ BFK466-55 spring-applied brake is designed for converting mechanical work and kinetic ener-
gy into heat energy, at a slipping speed of 12 m/s. Due to the static braking torque, loads can be held at
standstill.
Emergency braking at higher speeds is possible. Here, the maximum permissible speed must not be exceed-
ed (refer to
The stator (1) is supplied in heat class F. The temperature limit of the coil is 155 °C.
The brake is designed for a maximum switching time (duty cycle) of 60%.

3.1.2
Brakes
During braking, the friction lining carrier (7) and the affixed friction lining are pushed against the axially fixed
brake disc. Almost simultaneously, the caliper moves in the opposite direction on the guide sleeves (9), so
that the friction lining on the flange (3) is also pushed against the brake disc. The braking torque is supported
by the mounting flange via the guide sleeves (9). The asbestos-free friction linings ensure high braking
torque and low wear.
3.1.3
Brake release
When the brake is being applied, there is an air gap “s
L
" between the friction lining carrier (7) and the pole
faces of the stator (1). To release the brake, the coils of the stator (1) are supplied with DC voltage from the
associated switching device. The resulting magnetic force pulls the armature plate (7) to the pole faces of
the stator (1) against the spring pressure. The caliper can then be on the guide sleeves (9) to the extent that
the brake disc (2) is released and is free to rotate again.
3.1.4
Emergency release option
An optional manual release (4) is available for briefly releasing the brake. This allows the load to be lowered
in the event of a power failure.
3.1.5
Release monitoring
The INTORQ BFK466-55 spring-applied brake is equipped with a microswitch (changeover contact) which
monitors the switching status. When the brake is released, the microswitch (10) toggles. This means that it
is possible to prevent the drive from being operated when the brake is closed.
