AKME Series Servo Motors
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.
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.
