Industrial electromagnetic brakes are used across a huge range of machinery, motors and automation systems. One of the most commonly encountered ranges is the Lenze INTORQ BFK458 brake.
These spring-applied, electrically released brakes are widely used on geared motors, conveyor systems, lifting equipment, production machinery and many other industrial applications.
However, when a brake fails or requires replacement, identifying the correct version can sometimes be more complicated than simply ordering another brake of the same physical size.
At Modern Drives & Controls, we supply Lenze INTORQ brakes and regularly help customers identify and replace BFK458 brakes.
What Is a Lenze INTORQ BFK458 Brake?
The BFK458 is an electromagnetic spring-applied brake.
In simple terms, the brake is applied by springs when power is removed. When electrical power is supplied to the brake coil, the brake releases and allows the motor or machine to operate.
This makes the brake particularly useful for applications where a machine needs to stop safely or hold its position when power is removed.
Common applications include:
- Geared motors
- Conveyors
- Packaging machinery
- Production machinery
- Material handling equipment
- Lifting and hoisting applications
- Automated machinery
Why Is It Important to Identify the Correct Brake?
Although two brakes may look physically similar, there can be important differences between them.
When replacing a BFK458 brake, factors that may need to be checked include:
- Brake size
- Brake torque
- Coil voltage
- AC or DC supply
- Mounting arrangement
- Hub or shaft dimensions
- Manual release options
- Encoder or feedback options
- Switching requirements
Using the wrong brake could result in incorrect braking performance or problems fitting the brake to the motor.
For this reason, it is always best to identify the complete brake type number where possible.
Common BFK458 Brake Sizes
The Lenze INTORQ BFK458 range is available in a number of different sizes to suit different motor sizes and braking torque requirements.
The correct size will depend on the application and the motor the brake is fitted to.
Modern Drives & Controls regularly supplies replacement brakes from the BFK458 range and can help identify the correct size and specification for your application.
Replacing an Existing Lenze INTORQ Brake
If you have an existing brake that has failed, is worn, or needs replacing, the easiest way to start is by checking the brake nameplate.
The nameplate can provide important information about the brake, including the type number and electrical specification.
If the nameplate is difficult to read, or the brake part number is no longer available, we may still be able to help identify a suitable replacement.
A clear photograph of the brake and nameplate can often be enough to get started.
