Reduce noise
as the running smoothness of the worm gearmotor minimises noise pollution in the vicinity of your system.
Increase efficiency
because the gearmotor offers a high dimension of efficiency thanks to the combination with a helical gear stage in the gear unit.
Do you expect a drive solution to impress with its high power rating and efficiency? Then we recommend our high-quality worm gearmotors S..DR... These can be customised using the modular system. They offer you an enormous variety of sizes, gear ratios and motor sizes.
However, their greatest strength lies in their running smoothness and extremely low noise levels. In a nutshell: With the worm gearmotors S..DR.. worm gear motors are a powerful drive solution that you will hardly hear a sound from.
The overall concept also offers you many other practical product features and benefits. These include the significantly higher efficiency of helical gear/worm combinations compared to pure worm gear units. In this way, you save additional energy during the operation of your systems and can noticeably reduce your ongoing operating costs.
The low-noise worm gearmotors S..DR.. are available with a variety of AC motors to suit your individual requirements. In addition, you can freely configure all relevant properties. This allows you to effectively utilise all the advantages of this combination of low-noise worm gearbox and performance-optimised motor. You can achieve even more variance with the optional flange or foot-mounted design and the choice between solid and hollow shaft.
By choosing one of our gearmotors, you save time and money right from the selection and dimensioning stage. This is because our modular system enables a wide range of combinations of gear units and motors. This allows you to reduce operating costs, build on a long service life and benefit from our brand-typical maintainability.
