Due to their style and from being combined with a helical gear stage, the helical-worm gearmotors S..DR.. have especially high efficiency. Also, they are extremely low-noise and therefore avoid high noise emission levels.
Low-noise continuous operation: equipment unit combination optimized regarding efficiency
Do you expect a drive answer to impress you using its high level of functionality and efficiency? In that case, we’d recommend our high-quality helical-worm gearmotors EP to you. These could be implemented individually in the modular program. In this way, they offer you an enormous range of sizes, gear ratios and electric motor sizes.
However, their greatest strength is their running smoothness and their incredibly low noise development. One thing is certain – With the helical-worm gearmotors EP you are choosing a powerful drive solution that you will hardly also hear.
The overall concept also offers you many more practical product characteristics and benefits. Included in these are the significantly higher efficiency of the helical-worm combinations instead of single helical-worm gear models. This is one way you save additional energy in the operation of your systems and are able to noticeably reduce ongoing working costs.
You will receive the low-noise helical-worm gearmotors EP. – to suit your person requirements – with a wide range of AC motors. Furthermore, you can freely configure all the relevant properties. In this manner, you can effectively utilize all the benefits offered by this combination of low-noise helical-worm equipment unit and performance-optimized engine. Even greater variance may be accomplished thanks to the optional flange or foot-mounted style and by choosing between solid and hollow shaft.
