WEG Geared Motors WG20

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 4500 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 in the WG20 range provide a highly versatile and reliable product, with a wide range of possible applications.


Highly efficient

The gear units are two-stage designs featuring a large ratio range, which in turn makes them highly efficient. Furthermore, the products of the WG20 series demonstrate only extremely low power losses. On the one hand, this is achieved by low circumferential speeds in the input stage and, on the other hand, 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.
