On request, we will gladly deliver our motors and gearmotors with an integrated mechanical brake, which is available as single brake or double brake. The great number of available brake sizes and braking torques will certainly let you find the ideal brake for your specific requirements.
Find the right brake for you using our modular brake system
Our mechanical brake is a DC-operated electromagnetic disk brake that is released electrically and applied using spring force. The brake is applied when the voltage supply is interrupted. It meets the basic safety requirements.
The brake can also be released mechanically if equipped with a manual brake release. The mechanical release is enabled by a hand lever that resets automatically or an adjustable set screw. The brake is controlled by a brake control that is installed in either the motor terminal box or the control cabinet.
The variability in our modular brake design means that you can choose from up to 3 different brake sizes for installation on the motor required. Furthermore, the braking torque can also be varied by using different spring packages. The resulting multitude of braking torques also ensures the solution meets your requirements.
You can also choose safety-rated brakes that comply with EN ISO 13849-1 from our module brake system, which are specifically tailored for requirements in the area of functional safety. They enhance a safe brake system enabling the implementation of the "safe brake actuation" and "safe brake hold" safety functions based on your required performance level.
Our modular brake system also includes safety-rated brakes that can be used for horizontal operation up to PL d and vertical operation up to PL c in accordance with EN ISO 13849-1.
Double disk brake: The new component in our safe brake systems
A popular solution for implementing safe brake systems in industrial environments or in event technology applications is the use of 2 parallel motors with individual brakes – a safe but not particularly compact or cost-effective solution.
With the introduction of the state-of-the-art BF../BT.. double disk brakes, SEW‑EURODRIVE has now made it possible for you to implement a safe brake system with 2 individual brakes on one single drive. Both of these double disk brake designs achieve the maximum performance level e (PL e) in industrial systems and event technology applications (in theaters, for instance).
The advantages of the double disk brake: Less installation space, less installation work and therefore lower costs. Supplementing a safe brake system, they provide completely new possibilities for man and machine in the area of functional safety.

As well as the HR manual brake release with automatic re-engaging function that can be used to release both individual brakes in the double disk brake simultaneously, a new HT manual brake release option is also available. In addition to the basic function of the HR option, it includes a special mechanical component on the manual release lever. This allows for the release of either of the individual brakes or both of the brakes together.
The double disk brakes are available from August 2015 in sizes BF11/BT11, BF20/BT20 and BF30/BT30 and with a rated braking torque from 2 x 14 Nm up to 2 x 300 Nm.
- Manual brake release
- Contactless function and wear monitoring
- Special brake control
Other new additions to the program: The optional diagnostic unit for function and wear monitoring
The /DUE (diagnostic unit eddy current) brake
The sensor system provides continuous fully contactless function and wear monitoring for each individual brake. It displays the brake switching state, monitors the permitted wear and continuously measures the current working air gap.
