SEW-EURODRIVE BE2B Brake | 20 Nm DC Disk Brake for DT/DV & R Series Gearmotors, 180V DC / 400V AC
SEW-EURODRIVE BE2B spring-applied electromagnetic disk brake — 20 Nm max holding torque, 180 V DC coil (via BG/BGE rectifier from 230/400 V AC). Fits DR..63–100 motors & R-series gearmotors. Manual release optional.

Product Overview

The SEW-EURODRIVE BE2B​ is a DC-operated electromagnetic spring-applied disk brake​ (fail-safe type) configured as a factory option on EURODRIVE® DT/DV AC motors and R/K/S/W series gearmotors. It is spring-closed (applied when de-energized)​ and electrically released​ via a half-wave or full-wave rectifier (BG/BGE) mounted in the motor terminal box. The BE2 size provides a maximum holding torque of 20 Nm​ (reducible to 5/10/14 Nm via spring package selection). It is typically specified with 180 V DC coil voltage​ (excited from 230 V AC single-phase or 400 V AC three-phase via rectifier). A manual brake release lever (B-suffix = with hand release; -B often denotes version with manual release)​ is optionally available. The BE2B is commonly paired with DR..71S–DR..100L motors.

Degree of Protection​
IP54 (as mounted on motor) / IP65 optional with sealed cover
Noise Level (Release)​
≤ 70 dB(A)
Conformity​
EN ISO 13849-1 (basic safety brake), EN 60204-1, IEC 60034-1

Key Features

  • Fail-Safe Spring-Applied Design:​ Brake engages automatically on power loss — no backup power required for holding.
  • Compact BE2 Form Factor:​ Optimized for DR..63–100 motor frames — minimal added axial length vs. larger BE5.
  • Torque Adjustable:​ Same physical brake size supports 5–20 Nm via interchangeable spring sets — avoids oversizing.
  • Integrated Rectifier Compatible (BG/BGE):​ Half-wave (BG) or electronic (BGE) rectifier snaps into motor terminal box — no external control cabinet component needed.
  • Manual Release Option (B-suffix):​ Mechanical hand lever or screw for manual brake disengagement during maintenance/jogging.

Typical Applications

  • Vertical Lift / Hoist Drives:​ R-series or K-series gearmotors on conveyor elevators, bucket elevators — holds load on power failure.
  • Indexing & Positioning Tables:​ Where rapid stop and static hold are required between cycles.
  • Crane Travel End-Stops:​ Small overhead crane/trolley travel drives needing fail-safe stopping.
  • Packaging / Converting Machinery:​ Web tension control or emergency stop holding on intermittent-motion equipment.
BE2B is an option code​ (not a standalone shippable part) — it is factory-mounted on the DE (Drive End) of a SEW DT/DV motor or gearmotor. Standalone brake spare part reference for BE2 20Nm with 180V DC coil and 400V AC rectifier is typically 4998316​ (verify per regional catalog). For safety-rated PL d "Safe Brake" function, specify BMG02 or BMG2 instead. Rectifier type (BG 1.4 / BGE 1.4 etc.) must match motor supply voltage and is ordered as part of the motor option string.
