DuoDrive geared motor is now patented Revolutionary geared motor technology from NORD DRIVESYSTEMS
Two become one: The fewer interfaces, the higher the system efficiency – based on this maxim, NORD DRIVESYSTEMS introduced a revolutionary geared motor in a hygienic wash-down design one year ago, where the especially energy-efficient IE5+ permanent magnet synchronous motor and a single-stage helical gear unit are installed in one single housing.
The completely new, compact design with full integration of motor and gear unit in one single housing is an extraordinary leap in the development of geared motors and has now been successfully patented. The long-term durability and reliability of the innovative solution in terms of design and materials have been successfully proven in months of testing during the development of the DuoDrive, and thus real pioneering work has been accomplished in the field of geared motors. The integration has been decisively advanced to achieve optimal utilization of installation space. Along with the IE5+ motor on which it is based, the encoder, speed feedback and brake are all safely accommodated in the housing.
Excellent system efficiency
As a system, the very compact DuoDrive concept achieves a significantly higher energy efficiency than the already proven drive systems with IE5+ synchronous motor and bevel gear unit. At up to 92%, DuoDrive currently offers the highest system efficiency on the market in this power class and achieves very high efficiency 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. Market-compatible connection dimensions facilitate the replacement and integration into existing plant designs. The first available DuoDrive size covers gear unit speed ratios of i = 3.24 to i = 16.2 and is designed for output torque ranges of up to 80 Nm and speeds of up to 1,000 rpm. In addition to the high system efficiency, the smooth, unventilated and compact design, and the quiet running with minimum noise emissions are further important features of the new DuoDrive geared motor. Elimination of many wearing parts results in lower maintenance.
With approx. 4,700 employees today, NORD DRIVESYSTEMS has developed, produced and sold drive technology since 1965, and is one of the leading global full-service providers in the industry. In addition to standard drives, NORD delivers application-specific concepts and solutions for special requirements such as energy-saving drives or explosion-protected systems. In the 2021 financial year, annual sales amounted to 870 million Euros. NORD has 48 subsidiaries in 36 countries and further sales partners in more than 50 countries. They provide technical support, local stocks, assembly centres and customer service. NORD develops and produces a wide range of drive solutions for more than 100 industries, gear units for torques from 10 Nm up to over 282 kNm, supplies electric motors in the power range of 0.12 kW to 1,000 kW, and supplies the required power electronics with frequency inverters of up to 160 kW. Inverter solutions are available for conventional control cabinet installations as well as for decentralised, fully integrated drive units.
