Product Details:

KOLLMORGEN AKM73Q-ANCNR-00 is an extra large heavy-duty permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with EnDat single-turn absolute encoder and smooth plain shaft. It adopts 188mm IEC flange and Q winding stack design, delivering outstanding continuous stall torque and strong overload capacity, built for heavy gantry cross axes and large rotary positioning applications that only need absolute angle feedback within one rotation stroke. The single-turn EnDat encoder provides direct rotor angle reading after power-on without homing sequence, improving restart efficiency for limited-travel heavy-duty automation cells.

This servo motor uses high-resolution EnDat single-turn absolute encoder for digital feedback. It transmits stable rotor angle and speed data to matched Kollmorgen AKD servo drives to complete closed-loop motion control. Separate rotatable M23 connectors for power and feedback circuits isolate power noise from sensitive digital signals and reduce electromagnetic interference inside high-power electrical cabinets equipped with high-power inverters and switching components. The dual-cable structure supports stable signal transmission and convenient on-site maintenance.

This variant is non-brake design without integrated holding brake, suitable for horizontal heavy gantry platforms, large rotary storage turntables and bulk material heavy feed axes where power-off shaft locking is realized by external mechanical brake. The smooth plain shaft supports flexible coupling assembly to match different reducer and transmission layouts. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time winding temperature monitoring to avoid overheating damage during long-cycle fluctuating heavy load operation. The motor housing reaches IP54 protection grade to resist workshop dust and incidental coolant splashing. Optimized low cogging magnetic circuit suppresses torque ripple greatly, maintaining smooth low-speed tracking and high repeat positioning accuracy for ultra-large inertia payloads.

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, heavy inertia low-speed cycling test, insulation resistance inspection and vibration endurance test to guarantee stable performance in multi-shift heavy industrial production lines.

It is widely deployed on heavy gantry handling systems, large rotary storage carousels, bulk solid processing equipment, heavy mold transfer machinery and large stamping peripheral automation cells. Typical application axes include heavy gantry cross slides, large rotary positioning platforms, slow-stroke heavy pushing modules and clamp positioning units. Automation integrators select this ultra-high-torque single-turn EnDat variant for its excellent low-speed stability, reliable heavy-load tracking and seamless compatibility with Kollmorgen AKD motion control ecosystem.
