Sila-Coat and stainless steel for motors and worm gearboxes

For demanding sectors such as the food, pharmaceutical, and chemical industries, Groschopp offers customized motors and worm gearboxes specifically engineered for hygiene-critical environments. The focus is on two housing options and their flexible combination, designed to withstand strict cleaning requirements and aggressive environmental influences.

The innovative Sila-Coat coating serves as a highly cost-effective solution. In this process, the drive components are sealed using a specialized electrophoretic dip coating. The result is an extremely smooth, non-stick surface that offers significantly higher corrosion and alkali resistance than traditional hard anodizing. Because sticky residues struggle to adhere to it, cleaning time and detergent consumption in production are drastically reduced.

For areas subject to extreme mechanical stress—where cracks or flaking must be avoided at all costs—robust housings made of pure stainless steel are available. These are completely resistant to intensive high-pressure washdowns and aggressive chemicals. Despite their enclosed design, the drives achieve outstanding performance figures thanks to optimized cooling concepts. For instance, a convection-cooled stainless steel induction motor reaches an output power of 120 Watts, while the water-cooled variant delivers up to 470 Watts. For dynamic servomotors, water cooling even allows for a peak performance of up to 2,600 Watts at a speed of 6,000 rpm.

A key advantage of the system lies in its modular flexibility. Since not every part of a production line is exposed to the same mechanical stresses, the components can be freely combined using a modular system. This allows a stainless steel motor to be easily paired with a Sila-Coat-coated gearbox, ensuring a perfect balance of maximum hygiene, robustness, and cost-efficiency.
