Product Description:

The AKM44G-ACCN2-00 is a Kollmorgen servo motor belonging to the AKM Synchronous Servo Motors series. It is intended for closed-loop motion axes where precise position and velocity control must be sustained in packaging machines, assembly gantries, and similar automation stations. The motor’s IEC flange allows straightforward integration with planetary gearboxes or direct-drive couplings, while the standard rotor length index 4 provides medium torque capacity without extending the overall frame.

This model employs a feedback element that delivers 2048 lines/rev of incremental information to the drive. The sensor technology is a Comcoder, combining optical encoding with commutation tracks so electrical phase alignment is immediate after power-up. Position reference is limited to single-turn optical feedback, which suits point-to-point systems that home at startup rather than retain multi-turn data. Identification inside the control loop is handled through the EPC 15T code, ensuring parameter compatibility with standard Kollmorgen drives. Mechanically, the motor fits inside a frame that measures 84 mm across the mounting face, keeping inertia low for quick acceleration while maintaining enough cross-section for thermal dissipation. An IEC flange with accuracy class N supports concentric alignment to gearboxes, and the customization level is standard, so no special shaft or seal variants are applied.

The shaft end is machined with a keyway so torque can be transmitted through keyed hubs without relying on friction alone. Power and feedback cabling attach through two SpeedTec Ready connectors, reducing installation time because the bayonet fittings lock with a quarter turn. The stator uses a G winding that matches nominal voltage and current ratings typical of mid-range AKD drives, simplifying drive selection during machine design. Motion hold is provided by the servo loop itself, and the unit ships without a brake, making it appropriate for horizontal axes where passive holding torque is unnecessary.
