Due to their design and from being combined with a helical gear stage, the helical-worm gearmotors S..DR.. have especially high efficiency. They are also extremely low-noise and thus avoid high noise emission levels.
Low-noise continuous operation: equipment unit combination optimized with respect to efficiency
Do you expect a drive answer to impress you using its high level of performance and efficiency? In that case, we would recommend our high-quality helical-worm gearmotors EP to you. These could be implemented separately in the modular program. In this manner, they offer you a massive range of sizes, equipment ratios and engine sizes.
However, their greatest power is usually their running smoothness and their incredibly low noise development. A very important factor is for certain – With the helical-worm gearmotors EP you opting for a robust drive solution that you will hardly even hear.
The overall concept offers you many more practical product characteristics and benefits. These include the significantly higher performance of the helical-worm combinations instead of single helical-worm gear models. This is one way you save extra energy in the operation of your systems and are in a position to noticeably reduce ongoing working costs.
You will have the low-noise helical-worm gearmotors EP. – to suit your individual requirements – with a wide variety of AC motors. In addition, you can freely configure all the relevant helical worm gear motor properties. In this manner, you can effectively utilize all the benefits provided by this mixture of low-noise helical-worm gear unit and performance-optimized electric motor. Even greater variance may be accomplished because of the optional flange or foot-mounted design and by choosing between solid and hollow shaft.
