Kollmorgen AKM Washdown, Food Grade & Stainless Steel Servo Motors
The Kollmorgen AKM Washdown & Stainless Steel Servo Motor Series (featured model: AKM42S-ANCNC-00 3.4 Nm IP69K Stainless) is Kollmorgen's premium hygienic motion platform, engineered specifically for high-pressure, caustic chemical, and steam washdown environments in food processing, meat carving, pharmaceutical filling, and beverage packaging. Divided into three specialized executions—**AKM Stainless Steel (AKM2S, AKM4S, AKM5S, AKM6S)** constructed with 316L passivated stainless steel, **AKM Washdown (AKM-W)** with 2-part epoxy coating, and **AKM Food Grade (AKM-F)** with FDA-approved lubricants—these motors eliminate paint chipping and bacterial harboring traps. Rated for **IP67, IP66, and IP69K ingress protection** (tested against 100 bar high-pressure, 80°C steam jet cleaning), Kollmorgen hygienic servo motors incorporate dual-lip Viton shaft seals, laser-etched nameplates, smooth crevice-free housing, and single-cable **SFD3 / HIPERFACE DSL** digital feedback options for seamless drive integration with **Kollmorgen AKD and AKD2G digital servo amplifiers**.
