Long relegated to mere tech demonstrations and R&D facilities, solar thermal installations built around a central tower are now making the leap to full-scale production sites. Leading the way is Gemasolar in the south of Spain. In order to ensure precise and reliable operation of the plant’s mobile heliostats that focus the sunlight, the vast array comprising 2,650 mirrors is equipped with 5,300 robust geared motors supplied by NORD Drivesystems.

Gravel plant cuts costs and reduces maintenance expenditures by using geared motors. In many gravel pits, stone crushing plants and similar operations, motive power for conveyor belts is provided by shaft and belt drives. Until recently, this was the situation at the gravel plant of NorStone AS in Tau, located in the southwest region of Norway. Recently NorStone, a subsidiary of HeidelbergCement AG, decided to change to robust geared motors. This option promised lower investment costs and increased operational reliability, along with better process security. Reduced energy consumption thanks to higher efficiency was also anticipated.

The inauguration of NORD’s new Australian subsidiary, NORD Drivesystems Pty. Ltd., will take place on 6 October 2011 in the presence of NORD founder G. A. Küchenmeister, Mark Alexander, Managing Director of NORD Drivesystems Australia, and Gernot Zarp, Head of International Sales at NORD. NORD Drivesystems Australia commenced operations in 2010 with the construction of an assembly hall in the Melbourne suburb of Derrimut and started manufacturing gearboxes and electric motors. Investments into an extension of the paint facility and a modern drying room followed at the beginning of 2011.

More than two thirds of the energy consumed in industrial applications goes into the operation of electric drive technology. Since an electric motor’s energy consumption makes up about 98% of its total cost of ownership, investment in efficient drive technology is more than worthwhile. Nord offers energy efficient drive systems, including Unicase gearboxes with regenerative breaking, IE2 motors, and frequency inverters that automatically reduce magnetization when the motor is operated under partial load. All together it reduces energy consumption by a half compared to former solutions.

NORD Drivesystems issues its new M7000 electric motor catalog. At www.nord.com, the print version can be ordered and the electronic version is available for download. The catalog provides an overview of asynchronous low-voltage motors manufactured by NORD. It addresses in detail the implications of the switch to IE2.

NORD Drivesystems supplies PROFINET modules for the integration of frequency inverters into PROFINET environments. In the second quarter of 2011, NORD introduced new modular units for cabinet-mounted SK 500E inverters while a version for distributed SK 200E-type inverters will follow in the fourth quarter.
