NORD DuoDrive now with powers of up to 3 kW Patented geared motor for ultimate energy efficiency

By OEM Update Editorial July 7, 2022 2:39 pm IST

The patented DuoDrive from NORD DRIVESYSTEMS is a revolutionary integrated gear unit/motor concept in a hygienic wash-down design that now covers power ranges of up to 3 kW. The seamless integration of the gear unit and motor into a drive system is a quantum leap and sets new standards with regard to user friendliness and efficiency.

The fewer interfaces, the higher the system efficiency: NORD DuoDrive integrates a high-efficiency IE5+ synchronous motor into a single-stage helical gear unit, and with a system efficiency of up to 92% achieves one of the highest efficiencies on the market in this power class. Very high system efficiency is also achieved in the partial load range. It is thus future-proof and a real cost reducer. The constant motor torque over a wide speed range allows for consistent version reduction and reduction of operating costs. Together with the simple plug-and-play commissioning, this results in a significant reduction in the Total Cost of Ownership (TCO) in comparison with existing drive systems. DuoDrive is suitable for use in food and pharmaceutical industries as well as in intralogistics. 

Full compatibility with market standards 

In addition to the high system efficiency, the smooth, unventilated and compact design as well as the quiet running with minimum noise emissions are further important features. Elimination of many wearing parts results in lower maintenance. The patented geared motor is now available for powers of up to 3 kW with a continuous torque of up to 250 Nm and speeds of up to 1,000 min-1, and covers gear unit speed ratios of i=3 to i=18. Market-compatible connection dimensions facilitate the replacement and the integration into existing plant designs. 

Like all products from the NORD portfolio, DuoDrive is also compatible with NORD drive electronics and can be equipped with all common hollow shaft dimensions (20 to 40 mm) and flange versions (B5 and B14), or a torque arm. Depending on the customer requirements, Harting HAN connectors, M12 round plug connectors or a terminal strip are provided for the motor connection. Different options like encoder feedback or a holding brake are also possible with DuoDrive. Thanks to its design and operation with the frequency inverter, the DuoDrive can be universally used with the same motor variant worldwide.

Innovative geared motor in a hygienic wash-down design 

As it is easy to clean, corrosion-resistant and wash-down capable, DuoDrive is also ideal for use in hygiene sensitive and harsh environments, and ensures higher system availability and low cleaning costs through lower cleaning effort. The especially robust nsd tupH surface treatment is optionally available.
