With the DR.. modular motor system, we implement millions of drive combinations and move different systems and machines, worldwide.

It is easy to find the ideal energy-efficient motor for your application at SEW-EURODRIVE. The DR.. series has a suitable design in its range for the globally applicable efficiency classes IE1 to IE4: DRS.. for IE1, DRE.. for IE2, DRN.. for IE3 and DRU.. for IE4. Select the power and frequency within this motor design and you have already taken care of the most important selection criteria.

All other motor options are of course available independently of the efficiency class. A comprehensive braking concept and cost-optimized built-in encoders ultimately complement the motor range.

The motors of the DR.. series comply with the most important standards worldwide and the various requirements of the local energy efficiency regulations.

Motors of the DT56 and DR63 series complement the modular motor system in the range from 90 to 370 W.

Save time and optimize your motor selection, ordering and logistics processes. As a Global Player, we offer this range of products in 51 countries around the world.

Only half the solution without a gear unit? Then use our sophisticated modular system and combine an AC motor of the DR.. series with a helical, parallel shaft, worm, bevel or SPIROPLAN® gear unit of your choice. All of these gear unit types are already available off-the-shelf, combined with DR.. motors as gearmotors.

Of course, we also supply the right inverter technology for the controller and control. We develop and produce the drive electronics ourselves so that they are perfectly tailored to our motors and gearmotors, and to your application.

Driving the world

The world is our AC motors’ field of application. A motor design is available for each efficiency class. And, in turn, each motor type can be connected to the different energy grids around the world.


  • Comprehensive braking concept and combinations i.e. up to three different brake sizes per motor size featured in the range
  • Cost-optimized built-in encoders integrated into the motor
  • Significant time savings thanks to optimized processes in motor selection, order processing, and logistics
  • Motors for efficiency classes IE1 to IE4
  • Compact design saves space and costs
  • Future-proof, also as regards environmental protection (standards)
  • Reduction in operating costs when using energy-efficient motors; our energy-efficient motors conform to the efficiency classes
    • Standard Efficiency (IE1)
    • High Efficiency (IE2)
    • Premium Efficiency (IE3)
    • Super Premium Efficiency (IE4)
  • The “global motor” combines many energy efficiency regulations and laws in one design: the DR.. series
  • DR.. motors support global standards and norms
