Product Description:
The AKM54H-ACCNR-00 is a synchronous servo motor manufactured by Kollmorgen within the AKM Synchronous Servo Motors series. The unit converts drive current into precisely regulated torque for positioning axes, pick-and-place stages, and other closed-loop automation tasks that require fast response and repeatability. Its compact envelope allows direct attachment to gearboxes or linear stages, making it useful in packaging, electronics assembly, and material-handling equipment that rely on dense motion layouts and consistent axis control.
The motor is supplied without a brake, so holding force must be generated by the drive or by an external mechanism. Power and feedback connections exit through 2 SpeedTec Ready connectors, enabling keyed, tool-free cabling. Inside the back housing, a resolver with 2-pole resolution provides rotor position feedback for servo loops, and its size category is Size 10/15/21 to match standard drive electronics. The face mounting pattern uses an IEC flange with accuracy N, which helps maintain concentric alignment with metric gearheads. A 108 mm frame width supports a high torque-to-length ratio while keeping the envelope compatible with existing AKM mounting spaces. The motor is supplied in the standard customization level, so its winding, feedback, and housing options follow the standard configuration for this model.
The motor uses a single-turn inductive position sensor, which eliminates gears and helps maintain accuracy under vibration. The extended lamination stack uses rotor length index 4, adding active iron without changing the frame width. Mechanical power is transmitted through a shaft with a keyway, which supports slip-fit couplings in common motion systems. The motor also uses winding designation H, which balances phase resistance with thermal limits for medium-voltage servo drives.
