Due to their design 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 sound emission levels.
Low-noise continuous operation: gear unit combination optimized regarding efficiency
Do you expect a drive solution to impress you using its high level of functionality and efficiency? In that case, we’d recommend our high-quality helical-worm gearmotors EP for you. These can be implemented individually in the modular program. In this manner, they offer you an enormous range of sizes, gear ratios and electric motor sizes.
However, their greatest strength is usually their running smoothness and their incredibly low noise development. One thing is for certain – With the helical-worm gearmotors EP you are choosing a robust drive solution which you will hardly also hear.
The overall concept offers you a lot more practical product characteristics and benefits. These include the significantly higher performance of the helical-worm combinations as opposed to single helical-worm gear systems. This is how you save additional energy in the operation of your systems and are in a position to noticeably reduce ongoing operating costs.
