AKME
This page provides basic and support information for the AKME series of ATEX explosion-proof 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.
Part Number Scheme
The AKME part number scheme is for product identification only as not all combinations of features are possible.
Feedback
AKME servo motors are available with multiple feedback encoder options.
