2 Safety instructions
2.1 General safety instructions
❚ Never operate INTORQ components when you notice they are damaged.
❚ Never make any technical changes to INTORQ components.
❚ Never operate INTORQ components when they are incompletely mounted or incompletely connected.
❚ Never operate INTORQ components without their required covers.
❚ Use only accessories that have been approved by INTORQ.
❚ Use only original spare parts from the manufacturer.
Keep in mind the following during operations:
❚ Depending on the degree of protection, INTORQ components may have both live (volta ge carrying),
moving and rotating parts. Such components require the appropriate safety mechanisms.
❚ Surfaces can become hot during operation. Take the appropriate safety measures (to ensure contact/
touch protection).
❚ Follow all specifications and information found in the Operating Instructions and the corresponding doc-
umentation. These must be followed to maintain safe, trouble-free operations and to achieve the specified product characteristics.
❚ The installation, maintenance and operation of INTORQ components may only be carried out by quali-
fied personnel. According to IEC 60364 and CENELEC HD 384, skilled personnel must be qualified in
the following areas:
- Familiarity and experience with the installation, assembly, commissioning and operation of the product.
- Specialist qualifications for the specific field of activity.
- Skilled personnel must know and apply all regulations for the prevention of accidents, directives,
and laws relevant on site.
2.2 Disposal
The spring-applied brake consists of different types of material.
❚ Recycle the metal and plastic parts.
❚ Ensure professional disposal of assembled circuit boards according to the applicable environmental reg-
ulations.

3 Product description
3.1 Application as directed
INTORQ's spring-applied brakes are intended for use in machines and systems. They may only be used for
purposes as specified in the ordered and confirmed by INTORQ. The spring-applied brakes may only be operated under the conditions specified in these Operating Instructions. They may never be operated beyond
their specified performance limits. The technical specifications ( 16) must be considered for proper and
intended usage. Any other usage is consider improper and prohibited.
3.2 Layout
This chapter describes the variants, layout and functionality of the INTORQ BFK458 spring-applied brake.
The basic module E is adjustable (the braking torque can be reduced using the adjustment ring). The special
feature for basic module L (with an identical design) is the more dura ble materials (torque support, guide
pins, toothed intermediate ring, friction lining and gear teeth). The double-brake version is especially useful
in redundant braking applications.

❚ Aluminium rotor with toothed intermediate ring: Low-wear friction lining and low-wear gear teeth
The LongLife design can be configured modularly for sizes 6 to size 12 in combination with the specified rated torques. The specifications are as follows:
❚ The magnetic part corresponds to the design N.
❚ Rear holes and extensions are not possible.
❚ A microswitch in the size 12 is not configurable.

Fig. 3 Design of the INTORQ BFK458 spring-applied brake: Basic module N, doubled design with intermediate flange
Function
The spring-applied brake is a single-disk brake wi th two friction surfaces. The braking torque is generated
by several pressure springs with friction locking. The braking circuits are released electromagnetically. During the braking procedure, the spring-applied brake converts kinetic energy into heat energy. Due to the static braking torque, loads can be held at standstill. Emergency braking is possib le at high speed of rotation.
Note that the wear will increase when there is emergency braking with high switching energy.
Braking and release
During the braking procedure, the inner and outer springs use the armature plate to press the rotor (which
can be shifted axially on the hub) against the frict io n surfa c e. T he asb est os-fre e f r ict ion lining s e nsure h igh
braking torque and low wear. The braking torque is transmitted between the hu b and the rotor via gear teeth.
When the brakes are applied, an air gap "s
L
" is present between the stator and the armature plate. To release
the brake, the coil of the stator is energised with the DC voltage provided. The resulting magnetic flux works
against the spring force to draw the armature plate to the stator. This releases the rotor from the spring force
and allows it to rotate freely.
Brake torque reduction
For the basic module E, the spring force and thus the brake torque can be reduced by un screwing the central
adjustment ring.

3.3 Optional configuration
3.3.1 Manual release (optional)
To temporarily release the brake when there is no electricity available, a manual relea se function is available
as an option. The manual release can be retrofitted (for installation refer to 41).
3.3.2 Optional microswitch
The micro-switch is used for the release check or for wear monitoring. The user is responsib le for arrang ing
the electrical connection for this optional microswitch.
❚ Usage for the (air) release check: The motor will start only after the brake has been released. This ena-
bles the microswitch to monitor for errors (e.g. when the motor does not start because of a defective
rectifier, if there are broken connecting cables, defective coils, or an excessive air gap).
❚ Usage for monitoring wear: The brake and motor are supplied with no power when the air ga p is too
large.
3.3.3 Optional encapsulated design
This design not only prevents the penetration of spray water and dust, but also the spreading of abrasion
particles outside the brake. This is achieved by the following encapsul ation:
❚ A cover ring over the armature plate and rotor.
❚ Cover plate
❚ Shaft seal (can be supplied for continuous shaft).
3.3.4 Optional CCV
The Cold Climate Version (CCV) allows the brake to be operated at lower ambient temperatures.

4 Technical specifications
Usage conditions for the INTORQ spring-applied brake
❚ Degree of protection:
- The brake is designed for operation under the environmental conditions that apply to IP54 protection. Because of the numerous possibilities of using the brake, it is still necessary to check the f unctionality of all mechanical components under the corresponding operating conditions.
❚ Ambient temperature:
- -20 °C to +40 °C (standard)
- -40 °C to +40 °C (Cold Climate Version: CCV)
4.1 Brake torque reduction
For basic module E, the brake torque can be reduced using the adjustment ring in the stator. The adjustment
ring can be unscrewed to the maximum protrusion of "h
Emax.
" ( 17 and 56).
NOTICE
Please observe that engagement times and disengagement times change de pending on the
brake torque.
