The drive towards optimal protection

In almost all industries, it is important to protect plant and machinery efficiently, as well as the drive technology used from external influences, such as dirt, moisture, spray water and aggressive media. Motors and drives from Nord Drivesystems are already designed with a high level of protection, the company points out. Furthermore, the company points out, “high-performance coatings, paints and finishing processes protect the surfaces of drive systems, and ensure an aesthetic and uniform appearance”.

High-solid paints protect the environment

For paint finishes, NORD uses the latest generation of high-solid paints, which much reduce the emission of solvents far below the legally required limits, it says. With up to 80%, high-solid paints contain a large proportion of solid material and combine the emission benefits of hydro paints with the functionality of solvent-based coating materials. Also, the lower solvent proportion of only 20% allows for very short drying times in production – a decisive advantage over water-based coating systems.

Powder coatings for the electrical industry

For the electrical industry, NORD offers robust and long-life powder coatings. The treated surfaces are resistant to impact, scratches and wear. They are resistant to weather and chemicals, and are even more robust than conventional NORD paints. “The anti-static properties of the electrically conducting powder paints prevent static charging of the drive technology and so downtimes are reduced to a minimum,” adds NORD. “A further advantage: powder coatings are free from solvents and make an important contribution to protecting the environment.”

Thanks to a special method, the surface is made corrosion-resistant and harder, and makes aluminium behave like stainless steel with regard to corrosion protection, comments Nord. “This is not a coating, but a surface treatment that creates a protective layer, which is permanently bonded to the substrate material. So nothing can detach or flake off. Damage remains locally restricted and does not spread.”

The drives are said to be easy to clean, and largely resistant to acids and alkalis. It is even possible to use high-pressure cleaners or apply aggressive media. An nsd tupH treatment is available for most of the NORD modular drive systems made from aluminium. They are described as not only suitable for hygienically sensitive applications in the food sector, but also for various applications in process and pharmaceutical industries. They are typically used on conveyor belts, pumps, mixers or agitators, but also in water and sewage plants and car wash facilities.
