Nord Drivesystems patents DuoDrive geared motor

By installing an energy-efficient IE5+ permanent magnet synchronous motor and a single-stage helical gear in one single housing, the DuoDrive is very lightweight and compact, but still boasts a very high power density. Nord Drivesystems has now successfully patented the full integration of motor and gear unit. 

The long-term durability and reliability of the innovative solution in terms of design and materials has 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 an optimal utilisation 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.

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 the 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.
