New protection for Lenze servo drives in extreme conditions

New protection for Lenze servo drives in extreme conditions Lenze have extended their OKS surface protection system from standard geared motors to servo motors and servo geared motors. In industry there are many fields of application where a standard paint finish is not resistant enough for the working environment. Examples are increasing humidity outdoors or in cold stores, presence of salt in marine environments, and chemicals as found in some industrial processes. Lenze were already able to offer 3 increasing levels of protection to standard geared motors that suits these conditions. Now the same protection can be applied to servo motors and geared motors offering an attractive alternative to stainless steel components.

The highest of the three protection levels, the OKS-L, meets category C3 of EN ISO 12944-2 suiting use with the presence of water, chemicals and even high ambient temperatures. A primer coat plus two top coats are applied with a final colour that can be customer specified. Fasteners are zinc coated and sealing rings are applied to them. Optional are output shafts and nameplates in stainless steel. Chemical resistance is good for ammonia, oils, diesel fuel, cleaning solvents and acetic acid.

The availability of Lenze servo motors and geared motors with standard opinions for environmental protection makes it easy for the customer to specify. Compared to products with stainless steel construction, lead times are short with only 10 extra days for the finish and surcharges are low. The choice of gearboxes covers planetary, helical, bevel, helical bevel and helical worm.
