Product Details:

KOLLMORGEN AKM43E-ANSNS is an 84mm frame permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with ComCoder incremental encoder and keyed shaft. It delivers steady medium-high stall torque up to 4.7 Nm and supports maximum speed of 6000 rpm, optimized for tension control and synchronous follow-up axes that require stable speed regulation and continuous cyclic operation. ComCoder combines commutation signals and incremental pulse output, offering reliable speed feedback for master-slave synchronized motion without absolute position retention after power loss.

This servo motor transmits incremental pulse and commutation signals to matched Kollmorgen AKD servo drives to build closed-loop speed and position control. The encoder structure is compact and less sensitive to moderate temperature fluctuation, making it a cost-effective choice for continuous web processing lines. Separate rotatable M23 power and feedback connectors isolate power circuit from signal circuit and suppress electromagnetic noise interference inside electrical cabinets with inverters and frequency converters.

This variant is non-brake design without integrated holding brake, intended for horizontal unwind and rewind rollers, continuous feed axes and rotary synchronized modules where static shaft locking is not required. The keyway shaft provides firm torque transmission with gearboxes and pulleys and prevents slippage under variable tension load. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time overheat protection during long-hour continuous running. The motor housing reaches IP54 protection grade to resist workshop dust and incidental liquid splashing. Optimized low cogging magnetic circuit reduces torque ripple significantly, maintaining uniform rotation speed which is critical for consistent web tension and avoiding material stretching.

It supports torque control, speed control and position control modes, and all motion parameters can be tuned conveniently via Kollmorgen WorkBench software. Standard IEC mounting dimensions support direct replacement of legacy AKM motors, simplifying on-site equipment renovation and spare part swap. Every finished motor passes complete factory validation before shipment, including ComCoder pulse signal check, tension stability test, load cycling test, insulation resistance inspection and vibration noise monitoring to guarantee stable performance in multi-shift continuous production.

It is widely deployed on film converting machines, paper processing lines, flexible packaging unwinding and rewinding stations, textile calender equipment and label slitting machinery. Typical application axes include tension control rollers, synchronized transfer drums, slitter feed modules and web guiding drives. Automation integrators select this ComCoder keyed-shaft variant for its steady speed tracking performance, reliable tension response and seamless compatibility with Kollmorgen AKD motion control ecosystem.
