Product Description:

The AKM42S-BKCN2-02 servo motor is produced by Kollmorgen and belongs to the AKM Synchronous Servo Motors series. It is designed to translate controlled current from a matched drive into precise rotary motion. This makes it suitable for positioning axes, pick-and-place heads, and light packaging spindles in industrial automation cells that demand repeatable accuracy and fast dynamic response. It can be used on indexing tables, feed axes, and other mechanisms where the drive must hold a commanded path through repeated motion cycles. A NEMA flange pattern also supports straightforward attachment to standard gearboxes and mounting plates.

This model is supplied without a brake, so power-off holding torque must be provided by external means when required. Power and feedback wires are routed through two SpeedTec Ready connectors, allowing quick-release installation while maintaining keyed plug orientation within the AKM family. Position data are produced with a native resolution of 2048 lines/rev, and the incremental signals are interpolated by the drive for fine velocity control. A Comcoder sensor integrates the encoder and commutation tracks in one element. The measuring element supports single-turn optical feedback, which provides high signal quality for each revolution and supports stable speed regulation. Because encoder and commutation information are combined in one assembly, the rear section stays compact and cable routing remains straightforward.

The feedback electronics are identified as EPC 15T, allowing the drive to apply the correct signal processing parameters automatically. The square frame measures 84 mm across to keep the cross-section small in multi-axis clusters, and torque is transmitted through an open keyway shaft that accepts conventional keyed couplings. The rotor length is indexed as 2, balancing inertia against peak torque for moderate-load duty cycles. This arrangement helps the motor fit compact machine layouts where adjacent axes must be mounted close together. The overall combination suits machinery that needs a small motor body while still using a standard keyed shaft connection for common couplings. A special winding code optimizes the voltage constant so the motor can reach rated speed on low-to-medium DC bus levels common in distributed servo packs.
