Product Details:

KOLLMORGEN AKM51G-ACCNR-00 is a 142mm frame permanent magnet synchronous servo motor from Kollmorgen AKM series, equipped with SFD smart feedback device and single hybrid cable design. It delivers 4.75 Nm continuous stall torque with low rotor inertia of 3.4 kgcm2 and rated speed up to 6000 rpm, optimized for fast cyclic positioning applications that prioritize quick acceleration and short cycle time. The SFD single-cable structure integrates power, feedback and temperature signal in one cable, reducing wiring complexity and cabinet space occupation compared with traditional dual cable motors.

This servo motor transmits rotor position, velocity and winding temperature data to matched Kollmorgen AKD servo drives via SFD digital interface. It supports automatic motor identification and fast parameter loading during commissioning, cutting setup time for mass machine production. The integrated rotatable hybrid connector suppresses electromagnetic noise interference inside high-power control cabinets filled with inverters and switching components.

This variant is non-brake design without integrated holding brake, suitable for horizontal transfer axes and fast pick-and-place mechanisms where static shaft locking after power loss is not required. It adopts smooth plain shaft for flexible coupling assembly. The stator winding uses Class F insulation material and embeds PTC thermal sensor for real-time overheat protection during repeated high-speed cyclic operation. The motor housing reaches IP65 protection grade, offering reliable defense against fine dust and coolant splashes. Optimized low cogging magnetic circuit suppresses torque ripple, ensuring stable and precise dynamic response during frequent start and stop 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 SFD communication test, high-speed cycle test, insulation resistance inspection and vibration noise monitoring to guarantee stable performance in multi-shift automation production lines.

It is widely deployed on automated material handling robots, high-speed sorting equipment, packaging pick and place stations, electronic assembly cells and light stamping transfer lines. Typical application axes include rapid transfer slides, pick positioning modules, cross feed units and reciprocating handling platforms. Automation integrators select this low inertia SFD variant for its outstanding dynamic response, neat single-cable wiring and seamless compatibility with Kollmorgen AKD motion control ecosystem.
