Motors: Gearmotor designed for washdown conditions

SEW-Eurodrive has introduced a hygienic gearmotor.

02/12/2009


Lyman , SC A new IP69K-rated motor with a smooth-bodied, hygienic design is at the heart of the new AsepticPlus (ASEPTICplus)gearmotor from SEW-Eurodrive. This hygienic gearmotor is designed to perform reliably in the high pressure, high temperature washdown conditions found in the food processing industry, where the aggressive cleaning agents and processes needed to maintain a hygienic environment are a frequent cause of electrical and mechanical failures.

The DAS motor is integrally mounted with SEW gear units to create the AsepticPlus gearmotor. The motor has a smooth surface without recesses, so there is no place for bacteria or contaminants to hide. Plus, the totally enclosed non-ventilated (TENV) motor prevents contaminants from being spread by airflow.

Other protective features of the gearmotor are stainless steel components, including blanking plugs, breather valves, screw plugs and output shafts. Special coatings and sealants are also used, including a three-layer epoxy paint which is heat-cured after every layer, as well as EPDM rings and double sealing with FKM on the output side. Stainless steel gear unit output shaft options include solid or hollow shaft with key or SEW’s innovative TorqLOC system.

SEW-Eurodrive is a manufacturer of integrated power transmission and motion control systems with global headquarters in Germany. In 2007, the SEW introduced a
