helical worm gear motor
Helical-worm gearmotors
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: equipment unit combination optimized with respect to efficiency
Do you anticipate a drive solution to impress you using its high level of performance and efficiency? In that case, we would recommend our high-quality helical-worm gearmotors EP for you. These can be implemented separately in the modular system. In this manner, they offer you a massive range of sizes, equipment ratios and electric motor sizes.
However, their greatest strength 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 are choosing a powerful drive solution that you will hardly also hear.
The overall concept also offers you many more practical product characteristics and benefits. Included in these are the significantly higher performance of the helical-worm combinations instead of single helical-worm gear models. This is how you save additional energy in the operation of your systems and are able to noticeably reduce ongoing operating costs.
You will receive the low-noise helical-worm gearmotors EP. – to suit your person requirements – with a wide range 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 offered by this mixture of low-noise helical-worm gear unit and performance-optimized electric motor. Even greater variance may be accomplished thanks to 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 are already saving money and time with this selection and project planning. It is because our modular system enables a multitude of combination options for gear products and motors. You can for that reason reduce operating costs, count on an extended service life and reap the benefits of simplified maintenance that’s characteristic of our brand.
