WEG WG20 geared motor
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.
The helical gear units come in nine housing sizes for nominal torques from 50 to 4500 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 C10 are available in both two and three-stage versions, for those applications in higher torque ranges.
