AC gearmotor R/DR series SEW EURODRIVE frequency converter/inverter

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 our modular system – take advantage of its benefits: for example, we offer pole-changing AC motors for countries with a 50 Hz or 60 Hz line frequency, with the required voltage of course. Our 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.

Our range of pole-changing AC motors mean that you can save time and optimize your motor selection, ordering and delivery processes. As a Global Player, we offer you this range of products in 51 countries around the world.

Only half the solution without a gear unit? Then you can use our modular system to combine our DR63 and DRS.. series 2-speed pole-changing AC motors with a helical, parallel shaft, worm, bevel or SPIROPLAN® gear unit of your choice. All these gear unit types are already available serially, combined as standard gearmotors.
