Pole-changing DR.. series AC motors (2 speeds)


The simple way of controlling machine and plant speeds economically: 2-speed motors. We offer pole-changing DR.. series AC motors with a power combination from 0.15 kW / 0.20 kW to 18 kW / 34 kW. With this large selection, you are sure to find the suitable motor for your application.
We supply pole-changing 2-speed AC motors in sizes and designs DR63 and DRS.. as 4/2 and 8/4-pole motors with speeds in a ratio of 1:2 and as 8/2-pole motors with speeds in a ratio of 1:4 (DRS.. only).


These motors also come from a modular system – take advantage of its benefits: for example, we offer Sew Eurodrive’s pole-changing AC motors for countries with a 50 Hz or 60 Hz line frequency, with the required voltage of course. The pole-changing motors naturally come with all the certifications required by international regulations, so you can use them anywhere in the world, for example in Canada (CAS certification), the USA (UR certification) or in China (CCC certification).


We also offer a wide range of additional features so that you can find the perfect drives to match your applications. For example, with three different brake sizes for each motor frame size, you can size the brake to ensure that braking brings the drive to a halt safely and only as fast as necessary.



  • Simple winding changeover switching gives you two motor speeds
  • Pole-changing motors are a simple and economic option for applications that need “only” 2 speeds
  • Pole-changing motors are not subject to globally applicable efficiency standards, even if only one of the two speeds is continually in use
  • A wide variety of additional features in the SEW‑EURODRIVE modular motor system and various speed ratios (1:2 and 1:4) offer you many potential uses
  • We develop pole-changing motors ourselves according to our own proven modular system and manufacture them according to our own quality standards, even in our series production.
