AKMH stainless steel servo motors are engineered to deliver dependable

servo performance in applications subject to frequent, aggressive washdown

and strict hygienic requirements. With robust stainless-steel construction

and IP69K protection, AKMH motors support open machine designs while

helping machine builders simplify cleaning, system integration and commissioning.

Designed for Efficient Cleaning

The AKMH motor housing is designed to minimize flat surfaces, crevices and

exposed fasteners that could retain moisture or contaminants. Sloped surfaces

and sealed interfaces support effective washdown procedures and help reduce

cleaning effort, contributing to improved machine availability and enabling use

in open machine designs without protective covers.

Flexible Servo Performance

The AKMH series is available in multiple frame sizes and winding options to support

a wide range of torque, speed and power requirements. This flexibility allows machine

builders to apply a consistent hygienic motor solution across multiple axes while

tailoring performance to specific application needs.

Features

• IP69K‑rated motor and cable designed for frequent high‑pressure, high-temperature

washdowns and aggressive cleaning agents

• Smooth, round 316L stainless steel housing for hygiene and corrosion resistance

• No external bolts, washers, fasteners or crevices that could trap contaminants

• Sloped rear cover prevents liquid pooling, even in vertical mounting

• EHEDG and 3A compliant hygienic design

• FDA‑approved, food‑grade materials and seals

Certified for Hazardous Locations

With ATEX and IECEx certifications, the AKME Series extends the AKM family to

support a wider range of HazLoc applications. From pharmaceutical production to

food processing, grain elevators and more, AKME servo motors provide compact,

scalable options for areas where explosive gases or combustible dusts may be

present occasionally.

Features

• Six frame sizes (54 – 188mm) for broad machine compatibility

• Designed for continuous torque from 0.37Nm to 50.4Nm

• Speeds up to 5.000 rpm

• Compatible with AKD, AKD2G, and Kollmorgen Essentials™ (KED) servo drives

• Supports 75 Vdc, 120. 240. and 400 Vac systems

• Single- and dual-connector feedback devices include SFD-M; Hiperface DSL;

Resolver; Comcoder; EnDat 2.2; BiSS B

• IP64 protection for harsh industrial environments

• Standard Kollmorgen motor cables (1–25 m)

AKME servo motors are built on the proven performance of the AKM servo motor

platform, with additional design features to achieve ATEX and IECEx certification

for operation in gas Zone 2 and dust Zone 22 hazardous locations. To suit a wide

range of applications, these motors are available in frame sizes 2–7 to work with

drives powered by 75 Vdc, 120. 240 or 400 Vac., speeds up to 5.000 rpm and with

a complete selection of absolute feedback positioning devices.

Matched with Kollmorgen AKD, AKD2G and Kollmorgen Essentials™(KED) servo

drives, AKME servo motors deliver optimum torque density, responsiveness and

precision in a complete, feature-rich motion solution for locations that may

occasionally be exposed to ignitable gases or dusts.

Features

Kollmorgen Essentials servo motors suit a wide range of needs, eliminating the need for designers to stock specific excess inventory.

• Choose from eight power ranges from 200 to 4.000 watts and frame sizes from 58 to 138 mm

• Windings rated for 120. 240. 400 or 480 VAC

• 3.000 rpm rated speed, with a maximum speed of 6.000 rpm

• Option for integrated 24 VDC brake

• Industry-standard mounting reduces the need for excess inventory and improves field flexibility

• With a simple shaft key kit, users can adapt the shaft configuration to any smooth or keyed shaft coupling type—ready, off-the-shelf, for any application

SFD-M

With the integrated SFD-M device providing multi-turn absolute feedback to the highly responsive drive, 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

Kollmorgen Essentials servo motors deliver exceptional performance and versatility across eight power ranges from 200 to 4.000 watts and frame sizes from 58 to 138 mm. Each motor features our breakthrough SFD-M multi-turn absolute feedback device with energy-harvesting technology that eliminates battery backup requirements while providing positioning performance comparable to Hiperface and EnDat systems. With industry-standard IEC mounting, an innovative shaft key kit for maximum installation flexibility, and plug-and-play compatibility, these motors are engineered to reduce complexity, inventory costs, and setup time while delivering the reliability and performance your applications demand.
