    • The built-in encoder is fully integrated into the motor
  • Modular DR.. series motor system
  • The new modular system of asynchronous AC motors from SEW-EURODRIVE is a development based on the established motor series.
  • When developing energy efficient motors, SEW-EURODRIVE became the first company in the world to succeed in using die-cast copper technology in industrial high-volume series production in 2002.
  • The modular DR.. motor series includes the 3 types of energy efficient motors (IE1, IE2 and IE3) along with the perfect brake concept – up to 3 different brake sizes per motor size – as well as cost-optimized built-in encoders integrated in the motor. The DR.. motors comply with all worldwide standards and already fulfill the new parts of the IEC motors standard.
  • They bring a whole range of unique benefits to planners and users. One single series for millions of drive combinations

  • Modular brake system – The brake of your choice
  • The BE brake is based on the extremely successful BM(G) brake, but was further developed in many aspects. The size of the brake has always been inextricably linked to the size of the motor. “Less” brake is possible only by reducing the braking torque using a modified brake spring.
  • The new combination options of DR.. series motors with BE brakes are no longer subject to this restriction. The DR.. series motor can be combined with two or three different BE brake sizes.
  • The DR.. series motor can be combined with the ideal BE brake to match its requirements for the 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 endshield. Without opening the motor, the unit can now simply be removed and replaced – even with a larger or smaller brake.

  • Built-in encoder
  • The new built-in encoders in the modular DR.. series motor system are unique. Instead of an add-on encoder mounted to the fan guard of the non-drive end, the encoder can now be installed between the endshield and the fan. This means that any extra length caused by mounted encoders is avoided.

  • The additional features of the DR.. series motor and brakemotor are diverse and extensive. To provide a better overview, they were combined in groups.
