04/04/2022 • SEW EURODRIVE adds stainless steel servo gearmotors to its solutions and product portfolio. The PSH..CM2H.. series expands the range of uses in applications in the food, beverage and pharmaceutical industries. These are three industries with extremely stringent hygiene and cleanability requirements.

Calls for an incredibly short “time to market” are growing, especially in special machine design. Current developments have highlighted how quickly pressure on mechanical engineering can grow when production equipment is needed within very short periods of time to manufacture food or medicines. SEW EURODRIVE is therefore expanding its solutions portfolio to include stainless steel servomotors and stainless steel servo gearmotors. In doing so, the Bruchsal-based company is playing its part in ensuring machinery and systems can be created using its modular system, even for applications with stringent hygiene requirements. As a result, the precise hygienic drives can be delivered faster than is standard on the market.

The stainless steel servo gearmotors in the PSH..CM2H.. series have a hygienic design. They meet the strict guidelines of the European Hygienic Engineering Design Group (EHEDG) and the U.S. Food and Drug Administration (FDA). The drives have a smooth surface with a roughness of less than 0.8 µm and have no corners or edges.

In terms of durability and being easy to clean, the compact units, consisting of synchronous servomotor and planetary gear unit, have been designed in such a way that they can withstand high-pressure cleaning at high temperatures – even with chemical cleaning agents. The drive units are resistant to steam and corrosive cleansing agents – two of the typical requirements, especially for CIP and SIP (Clean in Place and Sterilization in Place) processes. The new stainless steel servo gearmotors from SEW EURODRIVE have a degree of protection of IP69K. They are part of the MOVI-C® modular automation system and cover five sizes with different lengths and nominal torques of 1.0 to 103.6 Nm, along with four different gear ratios per gear unit. Various feedback systems can be supplied for dynamic and reliable positioning. As such, the stainless steel servo gearmotors from SEW EURODRIVE’s PSH..CM2H.. series not only deliver the performance required for systems in the food, beverage and pharmaceutical industries, but they can also be flexibly integrated into existing machine designs.
