Product Description:

The AKM42G-ANC21-00 servo motor is manufactured by Kollmorgen as a member of the AKM Synchronous Servo Motors series. This brushless unit delivers tightly regulated torque and velocity to axes in packaging, material-handling, and general factory automation. By pairing with digital drives, it forms a closed-loop system that translates command currents into repeatable mechanical motion, supporting positioning tasks that demand high cycle rates and low settling times. That operating profile is well suited to indexing tables, feeders, and transfer axes that require consistent starts and stops throughout continuous production.

At the mechanical interface, the motor uses an 84 mm square frame that aligns to IEC mounting patterns, simplifying interchange with legacy actuators. Power and feedback are routed through 2 SpeedTec Ready connectors, a keyed design that reduces wiring errors and supports secure cable attachment. A 24 V holding brake is integrated so the load can be secured when the drive is disabled or during an emergency stop. For position detection, the rotor is equipped with a Comcoder generating 1024 lines/rev, allowing the drive to resolve fine motion increments without a secondary encoder. This arrangement supports medium-inertia axes where quick acceleration must be matched with stable standstill behavior.

The Comcoder provides single-turn optical feedback only, so multi-turn position tracking is handled by the controller rather than a mechanical backup. Torque is transferred through a smooth shaft, a profile selected for couplings that clamp directly onto the journal and avoid backlash introduced by keys. The motor uses an IEC flange with accuracy N, which keeps face runout within the limits required for servo precision and helps maintain alignment during installation. Internally, the stator carries the G winding set matched to 230 VAC class drives, and when combined with the rotor length index 2 lamination stack, it supports a balanced ratio of continuous torque to peak speed for mid-range automation axes.
