DR.. series AC motors (1 speed)

We offer you the ideal AC motor for any requirement: 2, 4, 6 and 8-pole motors, with powers of 0.09 kW to 375 kW and in the efficiency classes IE1 to IE4. Test us and the motors of the DR../DRN/DR2.. series in line or inverter operation!

DR../DRN/DR2... three-phase AC motors: efficient, powerful and usable worldwide

AC motor DRN355
The first time: DRN355 series three-phase AC motors
The first time: DRN355 series three-phase AC motors

With the DR../DRN/DR2.. modular motor systems, 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../DRN/DR2.. series has a suitable design in its range for the globally applicable efficiency classes IE1 to IE4: DRS../DR2S for IE1, DRN.. for IE3 and DRU.. for IE4. Select the power, voltage and frequency within this motor design and you have already taken care of the most important selection criteria.

Are you missing IE2 motors in our range? You don't have to - because the DRN.. motors in IE3 are their perfect successor. The weight and dimensions of the new DRN.. IE3 motors are only marginally different from comparable IE2 motors. And the best thing is: the selling price of a DRN.. motor only differs from that of a DRE.. motor with the same performance in a few cases.

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

The motors of the DR../DRN/DR2.. series comply with the most important standards worldwide and the various requirements of the local energy efficiency regulations in a power range from 0.09 to 375 kW.

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

Only half the solution without a gear unit? Then use our sophisticated modular system and combine an AC motor 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 gearmotors- optimised in terms of length, robust and perfectly tailored.

For the first time, the size 355 is found as a solo motor in the DRN.. modular system. Combinations with an industrial gear unit, regardless of whether with an adapter directly into the helical or bevel-helical gear unit or the complete drive package on the steel swing arm, are the best possibilities for using an IEC solo motor.

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