Product Details:

KOLLMORGEN AKM51G-ANCNR-00 is a 108mm frame permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with EnDat single-turn absolute encoder and smooth plain shaft. It adopts low inertia rotor design and supports high rated speed up to 8000 rpm, delivering stable medium torque and excellent acceleration performance for gantry axes and short-stroke high dynamic positioning applications. The single-turn absolute encoder provides direct angle position data within one rotation after power-up, which reduces machine reset time for limited-travel motion structures.

This servo motor captures rotor angle and speed signals via high-resolution EnDat single-turn encoder and transmits digital data to matched Kollmorgen AKD servo drives to form a high-precision closed-loop motion system. Separate rotatable M23 connectors for power and feedback circuits isolate power noise from sensitive digital signals and suppress electromagnetic interference inside high-power electrical cabinets. The dual-cable architecture brings stable signal transmission and convenient maintenance for industrial automation equipment.

This variant is non-brake design without integrated holding brake, suitable for horizontal gantry feed axes and high-speed reciprocating platforms where static shaft locking after power loss is not required. The smooth plain shaft supports flexible coupling assembly to match different transmission layouts. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time overheat protection during repeated high-speed cyclic operation. The motor housing reaches IP54 protection grade to resist workshop dust and incidental liquid splashing. Optimized low cogging magnetic circuit reduces torque ripple greatly, maintaining smooth motion track and consistent positioning accuracy for high-speed cutting paths.

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 EnDat signal calibration, high-speed cyclic endurance test, insulation resistance inspection and vibration noise monitoring to guarantee stable performance in multi-shift precision machining lines.

It is widely deployed on laser cutting gantry systems, high-speed plasma cutting equipment, electronic component sorting machines, routing machining centers and light-duty high-speed transfer lines. Typical application axes include gantry cross slides, fast reciprocating positioning units, cutting auxiliary feed modules and short-stroke pick and place platforms. Automation integrators select this low inertia single-turn EnDat variant for its outstanding dynamic response, stable high-speed tracking and seamless compatibility with Kollmorgen AKD motion control ecosystem.
