Product Details:

KOLLMORGEN AKM65M-ACCNR-00 is a large heavy-duty permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with ComCoder incremental commutation encoder and keyway shaft. It adopts 165mm IEC flange and M winding design, delivering high continuous stall torque and stable torque output for heavy roll-to-roll and low-speed continuous running automation axes. ComCoder provides incremental pulse signals and motor commutation feedback for closed-loop speed and tension control, it needs homing operation after each power cycle and cannot retain absolute position data.

This servo motor transmits incremental pulse and commutation signals to matched Kollmorgen AKD servo drives to realize stable master-slave speed ratio control between multiple driving rollers. It maintains steady speed ratio under fluctuating tension load, which is suitable for long-time continuous production lines that focus on synchronization rather than power-off position memory. Separate rotatable M23 dual connectors for power and feedback circuits isolate power noise from sensitive pulse signals and reduce electromagnetic interference inside high-power electrical cabinets equipped with inverters and switching components.

This variant is non-brake design without integrated holding brake, suitable for horizontal unwinding, rewinding rollers and large calender transfer axes where static shaft locking is completed by external mechanical brake structure. The keyway shaft provides reliable torque transmission with gearboxes and reducers and avoids slippage under variable heavy tension load. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time overheat protection during long-hour cyclic operation. The motor housing reaches IP65 protection grade, offering reliable defense against fine dust, coating powder and liquid splashing in molding workshops. Optimized low cogging magnetic circuit suppresses torque ripple greatly, ensuring uniform rotation speed to prevent material stretching, wrinkling and thickness 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 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 ComCoder pulse calibration, synchronous stability test, heavy load endurance test, insulation resistance inspection and vibration noise monitoring to guarantee stable performance in multi-shift continuous production lines.

It is widely deployed on large plastic extrusion lines, heavy film calender equipment, thick sheet coating machines, nonwoven fabric production systems and heavy rubber processing auxiliary rollers. Typical application axes include synchronized extrusion rollers, heavy rewinding drums, coating ratio control modules and web feeding driving units. Automation integrators select this high-torque ComCoder variant for its stable continuous running performance, strong anti-vibration capability and seamless compatibility with Kollmorgen AKD motion control ecosystem.
