Designed for harsh environments such as food and beverage processing or variable weather

applications, the lightweight AKMA servo motor delivers the performance and reliability you

need. These hard-working motors feature a cost-effective anodized aluminum coating,

and a form factor to meet your specific requirements in medium and heavy washdown

environments. For durability, cleanability, and versatility, our full line of AKMA motors is

built to perform.

Built for Durability

AKMA motors are engineered for performance and longevity in tough washdown environments

and uncertain outdoor conditions.

Unsurpassed durability starts with the motors’ hardened anodized aluminum coating that provides

strong chemical resistance in a wide pH range to withstand common cleaning agents in washdown.

You’ll find:

• Coating that is less vulnerable to scrapes, dents, and paint flaking than conventional epoxy

• Stainless-steel shaft with chromium oxide inlay maximizes lifetime of the shaft seal

• Vented design and “one-piece” housing structure eliminates the O-ring to reduce risk of water ingress

Built for Cleanability

AKMA motors are engineered for performance and longevity in tough washdown environments

and uncertain outdoor conditions.

In both food and beverage contact zones and dry clean environments, AKMA motors incorporate

critical design elements for more effective cleaning:

• Smooth surface ensures simple cleanability in environments where cleanliness is essential

• Round housing prevents contamination droplets from pooling

• IP69K-rated sealing allows higher pressure exposure for food-grade environments
