Product Details:

KOLLMORGEN AKM44J-ANSNS-04 is a heavy high-inertia permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with ComCoder incremental feedback and keyed shaft. It adopts 115mm flange and J winding configuration, delivering stable torque output for large rotary loads that demand consistent speed following and master-slave synchronous motion. The suffix 04 represents special OEM factory configuration, optimized for long-running web processing and roll-to-roll production lines with strict speed matching requirements.

This servo motor uses ComCoder feedback to output incremental pulse signals and motor commutation data, transmitting signals to matched Kollmorgen AKD servo drives for closed-loop speed and tension control. It is well suited for synchronous applications, though it cannot retain absolute position information after power loss. Separate rotatable M23 power and feedback connectors isolate power circuits from sensitive pulse signals and cut down electromagnetic noise interference inside high-power electrical cabinets.

This variant is non-brake design without integrated holding brake, intended for horizontal unwind, rewind rollers and large rotary drums where static shaft locking is not required. The keyway shaft provides solid torque transmission with gearboxes and pulleys and avoids slippage under fluctuating tension load. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time overheat protection during continuous multi-shift operation. 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 steady rotation speed which is critical to prevent material stretching, wrinkling and registration deviation.

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 calibration, synchronous speed stability test, long-duration tension cycling test, insulation resistance inspection and vibration noise monitoring to guarantee stable performance in continuous converting production lines.

It is widely deployed on large paper converting machines, film slitting and rewinding lines, textile calender equipment, flexible packaging roll handling systems and rotary printing auxiliary drives. Typical application axes include synchronized winding drums, tension control rollers, register correction modules and web transfer rotary units. Automation integrators select this high-inertia ComCoder variant for its excellent synchronous tracking capability, reliable heavy-load speed stability and seamless compatibility with Kollmorgen AKD motion control ecosystem.
