Due to their design and from being coupled with a helical equipment stage, the helical-worm gearmotors S..DR.. have particularly high efficiency. They are also extremely low-noise and therefore avoid high noise emission levels.
Low-noise continuous operation: gear unit combination optimized regarding efficiency
Do you anticipate a drive answer to impress you with its high level of performance and efficiency? In that case, we’d recommend our high-quality helical-worm gearmotors EP for you. These can be implemented separately in the modular program. In this manner, they offer you an enormous range of sizes, gear ratios and engine sizes.
However, their greatest strength is usually their running smoothness and their extremely 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 also hear.
The overall concept offers you many more practical product characteristics and benefits. These include the significantly higher effectiveness of the helical-worm combinations instead of single helical-worm gear systems. This is how you save extra energy in the operation of your systems and so are able to noticeably reduce ongoing working costs.
You will have the low-noise helical-worm gearmotors EP. – to suit your individual requirements – with an array of AC motors. Furthermore, you can freely configure all the relevant properties. In this manner, you can effectively utilize all the benefits provided by this combination 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 design and by selecting between solid and hollow shaft.
Save money and time
By opting for among our gearmotors, you already are saving money and time with this selection and task planning. This is because our modular system allows a multitude of mixture options for gear devices and motors. You can for that reason reduce operating costs, depend on an extended service life and reap the benefits of simplified maintenance that is feature of our brand.
