Gear-motor for industrial applications WG20

asynchronousACbevel

WG20 is the first geared motor range to be completely developed in-house at WEG. It comprises helical, parallel shaft, helical bevel and helical worm gear units with torques between 50 and 18,000 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 are two-stage designs featuring a large ratio range, which in turn makes them highly efficient. Furthermore, the products of the WG20 series demonstrate 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.


IN LINE WITH MARKET REQUIREMENTS
For maximum user convenience, the housing of the new gear unit series has been designed in accordance with market requirements. The crucial mounting dimensions of the design correspond with the specifications already established on the market which allows direct interchangability. This means that WG20 geared motors are not only suitable for use in new applications, but can also be easily integrated into existing systems as a replacement or for optimisation purposes.
