With the new size 355, SEW-EURODRIVE's three-phase motors of the DRN series meet the efficiency requirements IE3 up to 375 kW. This means that you can operate your system worldwide even at high power levels, regardless of whether you have to comply with the European Ecodesign Directive or another country-specific minimum efficiency requirement outside Europe.
Large drive powers are often required for solutions with industrial gear units. But even in this power spectrum, the correspondingly increased IE3 efficiency requirements often apply worldwide. For this reason, we have now extended the motors of the DRN series by size 355 especially for these applications and developed them for you. The DRN355 are part of our DRN.. motor modular system and meet all efficiency requirements and can therefore be used worldwide. The motors meet many local approvals and certifications.
The DRN355 are classic asynchronous motors in 4-pole design for mains operation at 50Hz or 60Hz or for use together with a frequency converter. In the IM B3 design, the feet of the DRN355 are an integral part of the housing, providing rigid mounting to the customer application. In addition, a standard air baffle is installed for better ventilation of the A-bearing.
Your advantages:
- - Industrial gear units
- - external oil supply and oil cooling systems
- - clutches on input and output side
- - brakes
- - IE3 motors with power ratings from 250 - 375 kW
- - drive packages on steel construction (swing arm or foundation frame)

Cables and wires in industrial robots and other moving machine parts are often required to withstand extreme stresses caused by torsion. Constant repetitive movements put materials under considerable strain. At the same time, operators expect components to function perfectly and reliably throughout their entire service life to avoid disruptions, outages and safety hazards.
For this reason, at HELUKABEL, we simulate intensive and continuous torsion stresses under realistic conditions with our high-tech testing equipment in Windsbach. We have several types of apparatus for doing this because some of our customers, for example those in the automotive industry, have very precise specifications for how a torsion test is carried out. The tests show that our cables and wires withstand speeds up to 1,000°/s, accelerations up to 2,000°/s² and torsion angles up to 720°. Hence, we make sure that each product always meets our customers’ high standards, and that they receive the impeccable quality they rightly expect from us as a leading supplier of cables, wires and accessories for more than 40 years.
