Product Details:

KOLLMORGEN AKM51G-CNC2R-00 is a 108mm frame permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with ComCoder incremental feedback and integrated 24V fail-safe holding brake. It adopts low inertia rotor design and supports high acceleration response, built for vertical transfer axes and lifting mechanisms that require reliable static shaft locking once power supply is lost. ComCoder supplies commutation signals and incremental pulse output for speed synchronization and cyclic motion control, without retaining absolute position data after power cycle.

This servo motor transmits incremental pulse and commutation signals to matched Kollmorgen AKD servo drives to form closed-loop speed and tension control. It delivers stable speed tracking for master-slave synchronous motion, which is widely used for continuous cyclic motion that does not need power-off position memory. 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 inverters.

This variant comes with built-in de-energized holding brake. When brake power cuts off, the brake locks rotor shaft firmly to prevent payload falling, which serves as essential safety protection for vertical lifting and suspended load applications. It is equipped with smooth plain shaft for coupling assembly. The stator winding uses Class F insulation material and integrates PTC thermal sensor for real-time overheat protection during long cyclic lifting 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, ensuring smooth and stable speed adjustment during lifting and descent motion.

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 signal calibration, load cycling test, insulation resistance inspection and vibration noise monitoring to guarantee stable and safe performance in multi-shift production lines.

It is widely deployed on automated vertical transfer elevators, heavy packaging lifting modules, material handling lifting stations, stamping vertical auxiliary slides and special lifting automation cells. Typical application axes include vertical lifting platforms, suspended load transfer units, hopper lifting drives and safety positioning lifting modules. Automation integrators select this ComCoder brake variant for its dependable power-off locking function, fast dynamic response and seamless compatibility with Kollmorgen AKD motion control ecosystem.
