Product Description:

The AKMH31E-CNKNCA5K is a servo motor produced by Kollmorgen, and it belongs to the AKM Synchronous Servo Motors series. It uses a Smart Feedback Device 3 encoder so the controller receives absolute shaft data and can close the velocity and position loops in real time. Acting as the rotary element in an axis, the motor converts drive current into controlled motion for conveyors, pick-and-place heads, and general automation where repeatable acceleration and stopping accuracy are required. Integration into face-mounted IEC frames simplifies mechanical alignment with pumps, actuators, and index tables.

It delivers a continuous torque of 0.96 Nm, sustained without overheating when the stator draws the rated phase current of 2.64 Arms. During transient moves, the motor can spin up to 8000 rpm, letting machinery reach high throughput while preserving surface velocity linearity for precise product handling. At these short duty peaks, the electromagnetic stack produces up to 3.88 Nm, giving actuators the headroom needed for load shocks or quick indexing. The windings accept a direct-current bus potential of 320 Vdc; this voltage level matches mid-power servo inverters and minimizes switching losses at full modulation.

The face-mount architecture is anchored by a bolt circle diameter of 75 mm and centered by a pilot diameter of 60 mm, giving repeatable concentricity when the motor is mounted flush against gearboxes or bulkheads. A keyed steel shaft projects 30.0 mm beyond the front face, allowing rigid coupling without relying on set-screw friction. For the initial acceleration surge, the drive may supply up to 12.0 Arms, a value that helps size fuses and cable gauges. An EPDM O-ring at the flange helps seal the mounting face, and the motor has a rotor length index of 3 with an overall Z-length of 166.5 mm.
