High-power drives are achieving higher and higher motor speeds and drive torque levels. However, despite the increased performance requirements, the installation space allocated for brakes is actually getting smaller. The innovative multi-coil technology forms the basis for this performance class.
INTORQ BFK468 spring-applied brakes are single-disk brakes with two friction surfaces. When deenergised, several compression springs are used to generate the braking torque through friction locking.
The BFK468 models may only be operated with a half-wave bridge rectifier. The half-wave bridge rectifiers switch from bridge rectification to half-wave rectification after a fixed overexcitation time. Terminals 3 and 4 are connected to the brake's DC circuit, while the induced voltage peak during DC operation (please refer to the circuit diagram entitled "Abbreviated switch-off times") is limited by an integrated overvoltage protection on terminals 5 and 6.

- Up to twice the braking torque in comparison with the BFK458
- Fixed or adjustable braking torque
- Fast operating times
- Long maintenance intervals thanks to large working air gap
The brake is released electromagnetically with holding-current reduction via an INTORQ half-wave bridge rectifier. During braking, the compression springs use the armature plate to press the rotor (which can be shifted axially on the hub) against the counter friction face.
Fields of Application:
- Brake motors
- Port facilities
- Stage machinery
- Storage technology
When the brakes are applied, the air gap sLN is present between the armature plate and the stator. A DC voltage is applied to the stator's coil to release the brake.
A Powerful & Complete Range:
- 4 sizes
- Standard voltages 205/103 V, 360/180 V (release voltage/holding voltage)
- Torque ranges from 100 to 2,400 Nm
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.
- Long rotor/hub connection with low rate of wear and tried and tested involute gear
- Low-wear, asbestos-free friction lining comes as standard
The DC voltage is then reduced to half by the accompanying switching device. Basic module E supports the use of the torque adjustment ring to reduce the braking torque.
- Can be frictionally engaged during dry running
- Special machining of the friction surfaces ensures that the characteristic torques are already achieved after just a few switching operations
- Fixed bearing is not required on the brake

The Hand Held EPM programmer allows you to select the source of the program to be installed, either from another previously programmed EPM, from a file within the EPM Programmer, or from a file on your personal computer. Use the EPM Programmer to save a drives program. This hand-held device holds up to 30 program files, and by using the Tech-Link Software and a standard RS-232 cable, you can archive the programs to your PC.
The Filter Elements and the brake chopper are integrated into the servo inverter and permit autonomous use in distributed control cabinet installations. Higher interference levels can be achieved without a larger mounting area by using suitable footprint filters (up to 55 kW). Lenze multi-axis drives are particularly suitable for centralised, compact multi-axis installations.
