Kollmorgen AKMA Servo Motors

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

Built for Lightweight Versatility

The lightweight design of AKMA motors makes them easier to install and maintain, while their high

torque density in a smaller size delivers performance improvement across demanding applications

including:

• Food and beverage processing

• Pharmaceutical and medical labs

• Radar stations and antenna positioners

SFD-M

With the integrated SFD-M device providing multi-turn absolute feedback, customers can expect

positioning performance comparable to Hiperface® or EnDat® feedback—without added cost.

• Single-turn resolution of 24 bits and multi-turn resolution of 16 bits

• Energy-harvesting technology eliminates the need for battery backup cables, which eliminates

costly setbacks from unplanned downtime due to battery failure, retaining absolute positioning

information even when the system is powered down or during a power outage or shutdown

• Onboard memory enables plug-and-play parameterization of the motor to compatible Kollmorgen

drives reducing setup time and enabling faster commissioning

Features

• Four frame sizes for a wide variety of machine designs

• Designed for continuous torque from 0.5Nm to 14.5Nm with peak torque at 1.4Nm to 38Nm

• Plug-and-play compatibility with Kollmorgen controls and drives

• Meets UL, CE, RoHS, UKCA standards

• 316L Stainless steel shaft

• Stainless steel hybrid connector with integrated Viton seal supports a single cable connection

to the servo drive.

• Feedback devices include Singleturn/Multiturn Smart Feedback Device (SFD3/SFD-M);

Hiperface DSL (FS); EnDat 2.2 (FS)
