helical worm gear motor
Due to their design and from being coupled with a helical gear stage, the helical-worm gearmotors S..DR.. have especially high efficiency. They are also extremely low-noise and therefore avoid high sound 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 functionality 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 system. In this manner, they offer you an enormous range of sizes, equipment ratios and electric motor sizes.
However, their greatest strength is definitely their running smoothness and their incredibly low noise development. A very important factor is for certain – With the helical-worm gearmotors EP you are choosing a powerful drive solution which you will hardly also hear.
The overall concept also 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 devices. This is one way you save additional energy in the operation 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. Furthermore, you can freely configure all the relevant properties. In this way, you can effectively utilize all the benefits offered by this combination of low-noise helical-worm equipment unit and performance-optimized motor. Even greater variance can be achieved because of the optional flange or foot-mounted design and by selecting between solid and hollow shaft.
Save time and money
By opting for one of our gearmotors, you already are saving time and money with this selection and task planning. It is because our modular system allows a multitude of mixture options for gear units and motors. You can as a result reduce operating costs, count on an extended service life and reap the benefits of simplified maintenance that is characteristic of our brand.
