Maintenance-friendly and suitable for condition monitoring

A difference is made between integral and modular design when BE.. brakes and motors from SEW‑EURODRIVE are connected.

  • Integrated design of the brake for motors of size 56 – 80 with BE02 – BE2 brake means the B-side endshield of the motor is an integral part of the brake with a friction surface.
  • The modular design of the BE03 brake for motors of sizes 63 to 71 and all BE.. brakes for motors from size 90 means the brake has a separate friction disk. The complete bearing of the motor is maintained even when the brake is removed.

The modular design allows for mounting of up to 4 brake sizes to one motor, especially for motors of size 90 and higher. The B-side endshield is to be regarded like a connecting flange, which accommodates the BE.. brake pre-mounted on a friction disk. When it comes to maintenance of the drive, the modular structure has the particular advantage that the brake can be removed without having to remove the entire drive from the system or disassembling it.

Adjustability

Brakes from BE05 upward allow you to adjust the working air gap quickly and easily as standard. This makes it possible to use the asbestos-free brake linings over a long period of time, even in wear-intensive applications.

In contrast, the BE02 and BE03 brakes cannot be adjusted. However, they are equipped with a considerably higher wear limit and thus provide a long service life, even without adjustment.

Internal brake plug connector from BE20 – BE122

Brakemotors from SEW‑EURODRIVE equipped with a brake of size BE20 or higher have an internal brake plug connector. The plug connector makes it possible to maintain the brake without having to loosen the wiring in the terminal box of the motor.

Optional with air gap monitoring

For predictive planning of the service intervals, BE1 – BE122 brakes on motors of sizes 80 – 315 can optionally be designed with air gap monitoring.

The diagnostic unit /DUE (Diagnostic Unit Eddy Current) is used for monitoring the working air gap. The diagnostic unit /DUE consists of the following components:

  • An evaluation unit in the motor terminal box that is supplied via a DC 24 V voltage.
  • A sensor, integrated in the magnet body of the brake

The diagnostic unit /DUE monitors the switching status of the brake and the wear on the basis of the current air gap. This information is output as digital or analog signals.
