Due to their style and from being coupled with a helical worm gear motor helical gear stage, the helical-worm gearmotors S..DR.. have particularly high efficiency. Also, they are extremely low-noise and therefore avoid high noise emission levels.
Low-noise continuous operation: gear unit combination optimized with respect to efficiency
Do you expect a drive option to impress you with its high level of overall performance and efficiency? In that case, we would recommend our high-quality helical-worm gearmotors EP for you. These could be implemented individually in the modular system. In this manner, they offer you an enormous range of sizes, gear ratios and engine sizes.
However, their greatest strength is their running smoothness and their extremely low noise development. One thing is certain – With the helical-worm gearmotors EP you are choosing a robust drive solution that you will hardly even hear.
The overall concept offers you a lot more practical product characteristics and benefits. Included in these are the significantly higher efficiency of the helical-worm combinations as opposed to single helical-worm gear models. This is how you save extra energy in the procedure of your systems and so are able to noticeably reduce ongoing operating costs.
You will receive the low-noise helical-worm gearmotors EP. – to fit your individual requirements – with an array 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 provided by this mixture of low-noise helical-worm gear 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.
