Product Description:

The AKM31H-ANMN2-00 is a synchronous servo motor produced by Kollmorgen as part of the AKM Synchronous Servo Motors series. It delivers precise rotational positioning and speed regulation for automated pick-and-place stations, packaging axes, and general machine tooling where closed-loop motion is required. Its electromagnetic design integrates with Kollmorgen servo drives, allowing rapid current adjustments that translate into responsive torque control, making the unit a core actuator in distributed manufacturing cells and robotic joints.

Motion feedback is generated by a 2048 lines/rev encoder built into a Comcoder module; this optical sensor provides position data at each 0.176° increment for fine velocity regulation. The device uses a single-turn optical architecture, so the controller resolves absolute rotor position within one mechanical revolution without multi-turn tracking. Because the motor is supplied without a brake, holding torque must be furnished by the drive or external mechanics when power is removed. A compact stator built on a 70 mm frame keeps inertia low and permits installation in confined machine spaces while still accommodating standard metric mounting patterns.

Mechanical interfacing uses an IEC with accuracy N flange pattern, enabling direct coupling to gearboxes or load adapters machined to the same tolerance class. The rotor stack is designated as index 1, indicating the shortest magnetic length available in the 31 frame; this choice favors high dynamic acceleration over continuous power density. A smooth shaft simplifies coupling with clamp hubs and eliminates keyway stress concentrations during high-speed reversing service. Winding code H corresponds to the copper fill and insulation used for nominal bus voltages around 320 V DC and helps keep thermal rise within Class F limits when operated at rated torque.
