Product Description:

The AKM23D-BNCN2-00 is a synchronous servo motor built by Kollmorgen and positioned within the AKM Synchronous Servo Motors series. The unit is intended for closed-loop motion axes where compact size and high-resolution feedback support positioning, indexing, or coordinated motion tasks in industrial automation. Its compact form helps it fit tightly spaced machine layouts, and it can be paired with a matched Kollmorgen drive for torque, speed, and position control. The combination of a compact frame and integrated feedback makes it suitable for axes that need accurate response without a large motor footprint.

The motor is supplied without a brake, so mechanical holding must come from the drive or an external clamp when the shaft must remain stationary after shutdown. A pair of SpeedTec Ready connectors keeps power and signal lines separate, which helps cable routing and keeps feedback wiring organized near the motor. Position data come from an integrated encoder that resolves 2048 lines/rev, allowing fine incremental moves under servo control. This encoder is the Kollmorgen Comcoder feedback device, which combines incremental and commutation tracks in one housing. It operates in a single-turn optical format, delivering absolute position within each revolution without multi-turn memory components. That arrangement supports accurate startup reference data and stable commutation during normal servo operation.

Mechanically, the motor mounts to a NEMA flange, letting it fit equipment that already uses that bolt pattern. The square housing width is 58 mm, and Kollmorgen assigns a rotor length index of 3 to balance inertia with continuous torque in this frame. A smooth shaft is provided for couplings that use clamp collars rather than keys, which can help maintain concentric alignment in compact drive trains. The motor uses winding designation D, which corresponds to the electrical values expected by compatible drives during operation. This combination of mounting style, shaft form, and winding selection supports straightforward integration into compact motion assemblies.
