Kollmorgen AKME servo motors are high-performance servo motors designed for precision motion control in hazardous industrial environments requiring ATEX and IECEx certification.

Built on the proven Kollmorgen AKM servo motor platform, the AKME range combines compact dimensions, high torque density and precise servo performance with design features that enable operation in Zone 2 gas and Zone 22 dust environments where explosive atmospheres may occasionally be present.

Available in multiple frame sizes, AKME servo motors support 75 VDC, 120 VAC, 240 VAC and 400 VAC systems, with speeds up to 5,000 rpm and continuous torque ratings up to 50.4 Nm. This provides a broad range of motor options for hazardous-area machinery requiring accurate and responsive motion control.

A wide selection of feedback options is available, including SFD-M, Hiperface DSL, resolver, Comcoder, EnDat 2.2 and BiSS B, providing flexibility for different control and positioning requirements. The motors are compatible with Kollmorgen AKD, AKD2G and Kollmorgen Essentials™ servo drives, enabling integration into complete Kollmorgen motion control systems.

With IP64 protection and compatibility with standard Kollmorgen motor cables, AKME servo motors are suitable for demanding applications including pharmaceutical production, food processing, grain handling, chemical processing, paint and coating systems, packaging machinery and other automation equipment operating in ATEX-regulated environments.

Micromech supplies Kollmorgen AKME hazardous environment servo motors as part of its range of servo motors, drives and motion control solutions for UK OEMs and machine builders.

Designed for harsh environments such as food and beverage processing, the lightweight AKMA servo motor delivers the performance and reliability you need. These hard-working motors feature a cost-effective anodized aluminium coating, and a form factor to meet your specific requirements in medium and heavy washdown environments and variable weather applications. 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

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

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 Smart Feedback Device, Gen. 3 (SFD3); Hiperface DSL; EnDat 2.2

Kollmorgen has designed custom solutions for challenging environments since our founding in 1916. The most notable were the motors used in Jason Jr., the ROV that was used to explore the Titanic. The culmination of these experiences has been leveraged in the AKMH series of motors. Designed for food contact and splash zones, the AKMH reduces cleaning time and maintenance, thus directly contributing to higher overall OEE for machines.

Features

Reduced Recall Risk. The Food Modernization Safety Act (FMSA) gives the US federal government the ability to shutdown facilities, recall food products, and levy stiff fines to ensure public safety in regards to food product manufacturing. The AKMH is designed to meet the toughest hygienic requirements in the industry in order to reduce the possibility of food borne illnesses and costly recalls.

Designed for Fast Cleaning and Increased Uptime. The AKMH stainless steel motor is designed to meet the standards for IP69K, EHEDG, and 3A and is built with FDA approved, food grade materials. The careful elimination of flat surfaces, cracks, and crevices prevents the build-up of foreign material and bacteria. The AKMH housing and cable can endure daily wash downs with high pressure, high temperature, and caustic chemicals. The robust design means that guards and covers are not required to protect the motor from harsh cleaning regimens. These AKMH features constitute quicker cleaning, keeping your machine running, and increasing the OEE of your manufacturing line.

Bottom Line. The Stainless Steel AKMH series is designed for strict aseptic machine applications. The AKMH comes in 19 standard motor sizes, with multiple standard windings for each to fit the many motor applications found in food, beverage, and pharmaceutical industries. Kollmorgen’s AKMH helps maintain the highest standard of machine cleanliness, increases OEE, and reduces the possibility of devastating recalls.
