Kollmorgen introduces Stainless Steel W Series motors.  These IP69K-sealed hygienic servomotors feature an all stainless steel, round housing design that promotes long life and reliable operation in harsh food, beverage and pharmaceutical applications, even subject to frequent high-pressure washdown cleaning.  With a robust design that eliminates the need for additional housing, an innovative venting system that eliminates the need for machine builders to supply compressed air to the motor and a 3 and 6 meter standard flying lead option that eliminates the need for intermediate cables, the W series simplifies machine design and component integration. 

Precision balanced, low-cogging and high torque density W Series motors use high grade stainless steel for all external and internal metal components, food-grade bearing grease, a food-grade shaft seal and a laser-etched nameplate.  They are available in 16 frame / stack combinations, delivering continuous torque to 80 Nm and peak torque to 390 Nm at rated speeds to 7500 RPM.  These attributes and performance enable food, beverage and pharmaceutical OEMs to specify exactly the right motor for the application without having to overpay for an over-specified motor, or settle for a standard motor with a modified housing. Food, beverage and pharmaceutical equipment machine builders generally use as many stainless steel components as possible, and are increasingly doing so even in areas where non-hygienic motors have historically been used.  Non-hygienic motors are difficult to clean and are prone to failure under the harsh operating conditions and rigorous cleaning schedules.  

Over time the exterior of painted motors can wear and chip, potentially causing paint to get into the end product.  Stainless Steel W Series Hygienic motors overcome these concerns and deliver the performance that will keep equipment up and running to maximize productivity. “Shutdowns by the U.S. Food and Drug Administration can be a public relations and productivity nightmare, and they can be prevented by utilizing hygienic components that are specifically designed for these environments,” says Gene Matthews, Product Manager, Kollmorgen.  “So whether an OEM is designing new equipment, or working a redesign to proactively prevent the possibility of a shutdown or to get an operation back up and running quickly after a shutdown, Kollmorgen’s Stainless Steel W Series motors are a hygienic, high-performance solution that can help.”
