Product Details:

KOLLMORGEN AKM52K-SSS2S-02 is a 142mm frame permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with ComCoder incremental encoder and integrated 24V fail-safe holding brake. The K winding version outputs high continuous torque and stable dynamic response, built for roll-to-roll tension axes that require power-off shaft locking to prevent material unwinding and roll reversal. The suffix 02 represents OEM special configuration for slitting and rewinding production lines, with reinforced brake torque rating for heavy web loads.

This servo motor transmits incremental pulse signals and motor commutation data to matched Kollmorgen AKD servo drives for closed-loop speed and tension regulation. It performs excellently for master-slave synchronized motion, though it cannot preserve absolute position data after power loss. Separate rotatable M23 connectors for power and feedback circuits isolate power noise from sensitive pulse signals and reduce electromagnetic interference inside high-power electrical cabinets with frequency converters.

This variant comes with built-in de-energized holding brake. Once brake power is cut off, the brake locks the rotor shaft firmly to stop roller backspin, which avoids material slack, stretching and safety accidents for suspended roll loads. It adopts keyway shaft for firm torque transmission with gearboxes and pulleys and prevents slippage under fluctuating tension load. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time overheat protection during long-hour continuous cyclic operation. The motor housing reaches IP54 protection grade to resist workshop dust and incidental liquid splashing. Optimized low cogging magnetic circuit suppresses torque ripple greatly, maintaining uniform rotation speed for stable tension control.

It supports torque control, speed control and position control modes, and all motion parameters can be tuned conveniently via Kollmorgen WorkBench software. Standard IEC flange 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 brake holding force test, ComCoder pulse calibration, tension cycling stability test, insulation resistance inspection and vibration noise monitoring to guarantee reliable performance in multi-shift converting production lines.

It is widely deployed on heavy roll slitting machines, flexible film rewinding lines, paper processing equipment, nonwoven winding systems and large textile calender rollers. Typical application axes include safety rewinding drums, tension control rollers, register correction modules and web guiding drives. Automation integrators select this high-torque ComCoder brake variant for its reliable power-off locking function, steady tension tracking and seamless compatibility with Kollmorgen AKD motion control ecosystem.
