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.

Our DR.. motor series can be combined with the ideal BE.. brake to match your requirements for braking torque or braking work. Moreover, brakes mounted on motors larger than size 90 have an additional special feature. The brake itself is mounted on a friction plate, which only has to be attached to the end shield. That allows you to replace the unit with a larger or smaller brake without needing to open, remove or change the motor.

Our brakes can also be released mechanically when equipped with a manual brake release. Two options are available for manual brake release:

For manual brake release with automatic reengaging function (..HR); a hand lever is included in the delivery.
For the lock-type manual brake release (..HF), a set screw is included in the delivery.

You can choose from a range of brake controls for controlling disk brakes with a DC coil, based on the requirements and the operating conditions. All brake controls are fitted as standard with varistors to protect against overvoltage.

The brake controls are installed either directly in the terminal box on the motor or in the control cabinet. For motors of thermal class 180 (H) and explosion-proof motors (except the /3D category), the control system must be installed in the control cabinet. The different housings for the brake rectifiers have different colors (= color code) to make them easier to distinguish.

Brake control in the wiring space

The supply voltage for brakes with an AC connection is either supplied separately or taken from the supply system of the motor in the wiring space. The supply can come from the motor line voltage only when motors with a fixed speed are used. The supply voltage for the brake must be supplied separately with multi-speed motors and for operation with a frequency inverter.

Furthermore, bear in mind that the brake response is delayed by the residual voltage of the motor if the brake is powered by the motor line voltage. The brake application time specified in the technical data for the brake, which is t_2l for cut-off in the AC circuit, applies only when the supply is separate.

Overview of technical data

The type and number of brake springs used determine the level of the braking torque. Unless otherwise specified in the order, the brake is fitted with the maximum braking torque (M_Bmax) as standard when ordered as a single brake. The standard braking torque in the stand-alone motor and the gearmotor is dependent on nominal motor torque and can deviate from the maximum braking torque. Reduced braking torques (M_Bred) can be selected in the same brake size thanks to additional brake spring combinations.

SEW‑EURODRIVE drives can be fitted with optional safety-rated components such as brakes and/or encoders.

An integrated safety-rated brake is clearly labeled by the FS logo (e.g. FS02) on the motor nameplate. This allows for the implementation of safety functions and their performance level evaluation according to EN ISO 13849-1.
