Product Description:
The AKM42E-ANCNAB-00 is a synchronous servo motor produced by Kollmorgen within the AKM Synchronous Servo Motors series. As an integral drive component, it converts three-phase drive output into precise rotary motion for indexing tables, gantry axes, and automated handling modules. The design combines high power density with low cogging, helping control loops maintain a tight following error even when loads vary across a production cycle.
A pair of SpeedTec-ready connectors on the stator housing separates power and feedback terminations, allowing tool-free locking and rapid cable connection. Rotor position is captured by a BiSS-B encoder that delivers a base resolution of 2048 lines/rev, supplying the drive with fine incremental data for smooth speed regulation. The encoder is implemented as a multi-turn optical device, eliminating the need for homing routines after power loss. Because the unit is supplied without a brake, the shaft can coast when power is cut, a feature suitable for belt-driven axes that rely on external clamping. The square frame edge measures 84 mm, allowing the motor to fit IEC-sized gearheads and brackets without adapter plates.
Mechanical alignment is handled by the IEC flange with accuracy class N, which maintains concentricity for repeatable coupling to machine frames. The rotor length index 2 shortens the magnetic stack to reduce inertia while preserving midrange torque capability. Output torque is transmitted through a smooth shaft, which is suitable for compression couplings or shrink discs used instead of keyed hubs. Thermal and electrical performance corresponds to winding code E, allowing the drive to apply the correct current tables during automatic tuning. For controller compatibility, the feedback option set is classified as AD34/AD58, indicating the connector pinout and protocol variants accepted by compatible Kollmorgen drive families.
