Due to their style 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 therefore avoid high sound emission levels.
Low-noise continuous operation: gear unit combination optimized with respect to efficiency
Do you expect a drive answer to impress you using its high level of performance and efficiency? If so, we’d recommend our high-quality helical-worm gearmotors EP to you. These can be implemented separately in the modular program. In this manner, they offer you a massive range of sizes, equipment ratios and electric motor sizes.
However, their greatest power is definitely their running smoothness and their incredibly low noise development. One thing is certain – With the helical-worm gearmotors EP you are choosing a robust drive solution that you will hardly also hear.
The overall concept offers you many more practical product characteristics and benefits. These include the significantly higher efficiency of the helical-worm combinations instead of single helical-worm gear products. This is one way you save additional energy in the procedure of your systems and so are in a position to noticeably reduce ongoing operating costs.
You will have the low-noise helical-worm gearmotors EP. – to fit your person requirements – with an array of AC motors. Furthermore, you can freely configure all of the relevant properties. In this way, you can effectively utilize all the benefits offered by this mixture of low-noise helical-worm gear unit and performance-optimized engine. Even greater variance can be achieved because of the optional flange or foot-mounted style and by selecting between solid and hollow shaft.
Save time and money
By opting for among our gearmotors, you are already saving money and time with this selection and project planning. This is because our modular system enables a multitude of combination options for gear products and motors. You can for that reason reduce operating costs, count on a long service life and benefit from simplified maintenance that’s feature of our brand.
