WEG Group - Transforming energy into solutions. WEG is a leading global manufacturer and solutions provider of drive technology, energy production and distribution, and automation systems and switchgear construction. Founded in Brazil in 1961 by three entrepreneurs, WEG has grown to become one of the most important global manufacturers of electric motors. WEG has more than 30,000 employees around the world. The annual turnover of around 3 billion euro reflects its increasing success. The company’s global presence is supported by branches in 29 countries, production facilities, and a network...

As one of the leading global manufacturers and solutions providers of drive technology, WEG's aim was to expand its extensive range of products by gear units produced in its own facilities. Perfect coordination of products throughout the drive train has put WEG in a position to offer customers even more superior and efficient solutions. Under the leadership of Watt Drive, the challenge was to develop a program which not only meets the current demands of the market, but also satisfied WEG's high quality requirements. The Group's own centre of excellence for geared motors in Austria, part of...

WG20 - a new generation of geared motors WG20 is the first geared motor range to be completely developed in-house at WEG. It comprises helical, parallel shaft and helical bevel gear units with torques between 50 and 1550 Nm. Already the two-stage units excel with their large ratio range, as well as being exceptionally efficient thanks to the sophisticated design. The light aluminium housings of the gear units up to 600 Nm and the robust cast iron housings from 800 Nm provide a highly versatile and reliable product, with a wide range of possible applications. Highly efficient The gear units...

Optimised design When designing the new gear unit range, the designers paid particular attention to develop a robust housing, opting for a light aluminium construction for the frame sizes up to 600 Nm. The die casting process used in production not only benefits from a smooth surface for demanding hygienic applications, but also features excellent heat conductivity. The housing design additionally enhances this property. The intelligently designed surface encourages heat dissipation from the internal gear parts, thereby aiding more efficient operation and a longer life. The housings for...

The helical gear units come in seven housing sizes for nominal torques from 50 to 1550 Nm and are available in both foot and flange designs. While the two smaller gear units (C00 and C01) are able to perform to their full potential with just two stages, the larger C03 to C08 are available in both two and three-stage versions, for those applications in higher torque ranges. 6 | WG20 Geared Motors

Design versions Standard mounting dimensions Taking the most significant standard mounting dimensions available into account, the design allows for easy integration of WG20 geared motors into almost any existing systems. Typical areas of application Machines for timber processing companies, presses, conveyor belts, rotary tables, pumps, packaging machines, bakery equipment, lifts, looms, screw conveyors and screw compressors. Gear size

Parallel shaft geared motors F Thanks to their structural design, parallel shaft gear units are particularly suitable for conveyor technology applications. All six sizes can be fitted with either a hollow shaft, output shaft, mounting flange or shrink disc. The ratio range of gear unit sizes F04 to F07 can be extended by a third gear stage. 8 | WG20 Geared Motors
