Geared motors from WEG

Watt Drive geared motors are the electro-mechanical key elements for low backlash, smoothly running and highly dynamic drive systems. The high-performance gear units are built to withstand the toughest industrial applications. The gear housings are machined on all sides and permit diverse mounting positions and applications, making them much sought after in the industry.

As a result, they are often to be found as part of our customers own machines. The smooth running of Watt Drive gear units and the outstanding load capacity of WATT teeth are achieved with 3D design supported by FEM (Finite Element Method). This tooth geometry guarantees optimum rolling contact under load.

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 18,000 Nm. These two-stage units excel with their large ratio range, as well as being exceptionally efficient thanks to the sophisticated design. The light, yet robust, aluminium housing of the gear units provide a highly versatile and reliable product, with a wide range of possible applications.

The gear units are two-stage designs featuring a large ratio range, which makes them highly efficient. Furthermore, they demonstrate only extremely low power losses.This is achieved by low circumferential speeds in the input stage and by reducing splashing losses due to optimised amounts of lubricant. These characteristics also have a positive effect on the gear lifetime. Under normal conditions of use, the geared motors up to 600 Nm are maintenance-free and lubricated for life.
