Product Description:

The AKM31H-ANCN2-00 is a synchronous servo motor manufactured by Kollmorgen within the AKM Synchronous Servo Motors series. It is intended for closed-loop motion axes in packaging machines, pick-and-place gantries, and similar automation where accurate velocity and position control are required to coordinate tooling and conveyors. Rotor length index 1 keeps the active stack short, reducing inertia for rapid acceleration, while the winding is optimized under designation H for mid-range line voltage operation.

This model uses an IEC flange with accuracy N configuration, allowing direct attachment to gearheads or mechanical frames without alignment sleeves. The square housing’s outside dimension is 70 mm, a frame size that balances torque density with compact installation. Mechanical power is delivered through a smooth shaft, eliminating keyway stress points in coupling hubs. Electrical terminations use two SpeedTec Ready connectors; these quarter-turn plugs simplify field wiring and maintain shield continuity for encoder and phase leads. For position feedback, the optical sensor provides 2048 lines per revolution, giving fine incremental resolution for servo loops that demand tight positional accuracy.

The feedback package is a Comcoder built on a single-turn optical principle; it outputs digital channels in the EPC 15T format, so modern drives can read absolute position immediately after power-up. This standard encoder architecture aligns with the motor’s standard configuration, meaning there are no mechanical or electrical deviations from the base design. The winding family, identified as H, establishes resistance and inductance values that match Kollmorgen’s AKD and S700 drives without manual tuning. Because the unit ships without a brake, holding torque must be supplied by the drive or external locking devices when power is removed.
