Helical-worm gearmotors

Their greatest strength is their running smoothness and their extremely low noise development. In a nutshell: With the S..DR.. helical-worm gearmotors you are choosing a powerful drive solution which you will hardly even hear.

The simple design makes for cost-effectiveness. The individual adjustment of torque and speed enables space-saving installation of our helical-worm gear units. Use S series helical-worm gear units as a cost-effective solution for meeting basic requirements in your machine or plant applications. The torque range extends from 92 to 4000 Nm. For the S..7p it is 105 Nm to 4300 Nm.

Adding in a helical gear stage means that significantly higher efficiency can be achieved than when using plain worm gear units. The linear power transmission makes these helical-worm gear units exceptionally smooth-running and low-noise. Why? Power is transmitted via the worm shaft and the worm gear to the input shaft. In a process that reduces torque impulses and facilitates low noise levels.
