Product Description:

The AKM41S-ANS22-03 is a brushless AC servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. Serving as the torque-generating element in coordinated motion axes, it converts drive current into precise rotational movement for packaging, electronic assembly, and material-handling lines. The motor’s compact frame and integrated feedback enable real-time position control, supporting rapid index moves and stable velocity regulation in closed-loop automation tasks.

To secure vertical loads during power loss, the motor incorporates a 24 V holding brake, which clamps the shaft whenever supply voltage is removed. Position data are generated by an integrated encoder that offers 2048 lines per revolution of native resolution; this pulse density lets the drive interpolate fine increments for smooth micro-positioning. The sensor platform is Kollmorgen’s Comcoder, which combines optical sensing with commutation tracks so the drive receives absolute phase information immediately after startup. The mechanical interface uses an IEC flange with accuracy class N, providing standardized pilot diameters while meeting the applicable concentricity tolerance. The square housing measures 84 mm across, allowing it to fit into machines with limited installation space.

The feedback element uses a single-turn optical design, so it reports one revolution of absolute angular position without a multi-turn gear train, reducing inertia at the rotor hub. Torque is transmitted through a smooth shaft, which simplifies connection to zero-backlash clamping couplings or integrated gearheads. Model code EPC 15T identifies the encoder protocol variant accepted by compatible Kollmorgen drives for digital communication of position and diagnostic data. A special winding tailors the stator impedance and back electromotive force constants to accommodate nonstandard bus voltages or peak current demands. This winding supports motion profiles that require electrical characteristics beyond those of the standard configuration. The special connector arrangement simplifies cable routing around nearby machine components and helps avoid sharp cable bends. A rotor length index of 1 keeps the magnetic stack and overall motor housing short for installations with restricted axial clearance.
