Product Description:
The AKM41S-ANSN2-03 is a brushless servo motor produced by Kollmorgen and supplied within the AKM Synchronous Servo Motors series. It converts regulated power from a matched drive into precise rotary position and velocity, supporting tight control-loop gains in automated equipment. Typical roles include indexing tables, electronic cams, and coordinated multi-axis stages where low mechanical latency and consistent torque are essential for cycle repeatability. With its compact frame and encoder-based feedback, the unit helps reduce machine footprint while preserving accuracy in high-throughput production lines.
The motor employs a Comcoder feedback device that produces 2048 lines per revolution of incremental data. When interpolated by the drive, this fine resolution lowers velocity ripple and improves settling time. The sensor is built as a single-turn optical encoder, and its internal EPC 15T code wheel maintains phase alignment throughout its service life. A smooth shaft interface allows zero-backlash clamping hubs to be mounted without removing a key. The square stator frame measures 84 mm across the mounting face, fitting common IEC gearheads and direct-drive arrangements. The assembly is supplied without a brake for axes that rely on electric holding torque rather than mechanical locks, reducing rotating mass for faster acceleration.
Electrical integration is handled through a special connector arrangement that combines power, signal, and protective earth connections within one keyed plug to simplify installation and limit wiring errors. The stator employs a special winding, allowing its resistance and back electromotive force to match alternate bus voltages permitted by regional standards. Mounting precision follows the IEC flange accuracy N classification, keeping the pilot concentricity compatible with planetary reducers. The rotor stack has a length of index 1, providing a short magnetic path that reduces the moment of inertia while maintaining continuous torque. This configuration supports responsive movement in packaging, inspection, and light machining applications where frequent acceleration and controlled positioning are required.
