NORD Drivesystems DuoDrive integrated geared motor

The NORD DRIVESYSTEMS IE5+ synchronous motor energy-efficient drive system is suitable for the food industry and intralogistics. The high-efficiency IE5+ motor has now been integrated into a single-stage helical gear unit — thus further optimising system efficiency — and is also launched in the next size.

By installing the motor and the gear unit in one single housing, DuoDrive is lightweight and compact, coupled with very high power density. The DuoDrive geared motor features high system efficiency and a consistent version reduction paired with a smooth, unventilated and compact design. Elimination of many wearing parts results in lower maintenance.  The new motor is now available in ventilated or smooth surface versions for powers from 1.1 to 4.0 kW with a continuous torque of 6.8 to 18.2 Nm.

DuoDrive is a NORD DRIVESYSTEMS integrated geared motor in hygienic washdown design where the IE5+ synchronous motor and the single-stage helical gear unit are installed in one single housing. As a system, the compact DuoDrive concept achieves a higher energy efficiency than the combination of IE5+ synchronous motor and NORDBLOC.1 bevel gear unit.

The first available DuoDrive size covers gear unit speed ratios of i = 3.24 to i = 16.2 and is designed for torque ranges of up to 80 Nm and speeds of up to 1000 min-1. As it is easy to clean, corrosion-resistant and washdown capable, DuoDrive is also suitable for use in hygiene-sensitive and harsh environments, and provides good system availability and lower cleaning costs through lower cleaning effort.

If required, the motors are provided with a smooth surface or the nsd tupH surface treatment. The IE5+ synchronous motors are available in two sizes with a smooth motor design suited for washdown applications in food and pharmaceutical industries.

In case of stringent requirements on surface and corrosion protection, nsd tupH surface treatment is the technology of choice. Thanks to a special method, the surface is made corrosion-resistant and harder and is claimed to make aluminium behave like stainless steel with regard to corrosion protection. This is not a coating, but a surface treatment that creates a protective layer which is permanently bonded to the substrate material so nothing can detach or flake off.  The drives are easy to clean and largely resistant to acids and alkalis. It is even possible to use high-pressure cleaners or apply aggressive media. nsd tupH treatment is available for most of the aluminium products in the NORD modular drive system, and suitable for hygienically sensitive applications in the food sector.
