Helical-worm gearmotors

Due to their design and from being combined with a helical gear stage, the helical-worm gearmotors S..DR.. have particularly high efficiency. They are also extremely low-noise and thus avoid high noise emission levels.

Low-noise continuous operation: gear unit combination optimized with respect to efficiency

Do you expect a drive solution to impress you with its high level of performance and efficiency? In that case, we would recommend our high-quality helical-worm gearmotors S..DR.. to you. These can be implemented individually in the modular system. In this way, they offer you an enormous range of sizes, gear ratios and motor sizes.

However, their greatest strength is their running smoothness and their extremely low noise development. One thing is certain – With the helical-worm gearmotors S..DR.. you are choosing a powerful drive solution which you will hardly even hear.

The overall concept also offers you many more practical product characteristics and benefits. These include the significantly higher efficiency of the helical-worm combinations as opposed to single helical-worm gear units. This is how you save additional energy in the operation of your systems and are able to noticeably reduce ongoing operating costs.

You will receive the low-noise helical-worm gearmotors S..DR.. - to suit your individual requirements - with a wide range of AC motors. In addition, you can freely configure all of the relevant properties. In this way, you can effectively make use of all the benefits offered by this combination of low-noise helical-worm gear unit and performance-optimized motor. Even greater variance can be achieved thanks to the optional flange or foot-mounted design and by choosing between solid and hollow shaft.

Save time and money

By opting for one of our gearmotors, you are already saving time and money with this selection and project planning. This is because our modular system enables a multitude of combination options for gear units and motors. You can therefore reduce operating costs, count on a long service life and benefit from simplified maintenance that is characteristic of our brand.
