Product Details:

KOLLMORGEN AKM42J-CCDNC-00 is a high inertia permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with ComCoder incremental encoder and commutation feedback. It adopts 84mm IEC standard flange and longer rotor stack, delivering stable high continuous torque and excellent inertia matching for large rotary loads that require smooth speed regulation and steady running performance. ComCoder integrates position commutation signal and incremental pulse output, which is widely adopted for speed synchronized axes and master-slave follow-up motion systems.

This servo motor uses ComCoder encoder to send incremental pulse signals and motor commutation data to matched Kollmorgen AKD servo drives. The drive can capture speed feedback and rotor phase information to implement stable sinusoidal current control. It is suitable for synchronous motion applications that do not require absolute position retention after power off. Separate rotatable M23 connectors for power and feedback circuits isolate power noise from pulse signals and reduce electromagnetic interference inside electrical cabinets with frequency converters.

This variant is non-brake design without integrated holding brake, intended for horizontal rotary drums and continuous synchronous feed axes where static shaft locking is unnecessary. It comes with keyed shaft structure to transfer heavy torque reliably with gearboxes and timing pulley assemblies. The stator winding uses Class F insulation material and integrates PTC thermal sensor for overheat protection during long-time synchronous 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 which is critical for color registration and continuous web processing.

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

It is widely deployed on rotary printing presses, web converting machinery, film stretching lines, textile calender equipment and large roll handling automation systems. Typical application axes include register control rollers, unwinding and rewinding drums, synchronous transfer rollers and continuous extrusion auxiliary drives. Automation integrators select this ComCoder feedback variant for its stable synchronous tracking performance, reliable commutation signal and seamless compatibility with Kollmorgen AKD motion control ecosystem.
