Product Description:

The AKM42E-BKMN2-00 servo motor is produced by Kollmorgen and belongs to the AKM Synchronous Servo Motors series. It is designed for closed-loop motion control, converting electrical commands from a servo drive into regulated torque and speed in automated assembly, packaging, or material-handling equipment. The unit integrates readily into multi-axis gantries, rotary tables, and conveyor diverters, providing consistent mechanical interchangeability across the AKM platform.

This configuration is supplied without a brake, so stopping and holding must be accomplished by the drive electronics or external mechanics. Position feedback is delivered by a 2048 lines/rev incremental encoder that Kollmorgen identifies as a Comcoder; the fine pulse count improves velocity estimation at low speeds. Internal Hall tracks inside the Comcoder supply commutation reference so the controller can energize the phases without additional sensors. A NEMA flange pattern pairs with the 84 mm frame dimension to fit standard gearheads and mounting plates. The motor uses the standard customization level and carries rotor length index 2, which gives it moderate inertia for dynamic indexing moves.

The feedback chain employs a single-turn optical scanning method and the code format labeled EPC 15T, giving an absolute reference within each revolution for homing routines. Mechanical power leaves the motor through an open keyway shaft that prevents rotational slip when coupled to hubs or pulleys, and the keyway helps minimize backlash during bidirectional duty cycles common on inspection or labeling stations. The winding designation e indicates copper fill, resistance, and inductance values, allowing drives to apply rated current without excessive heating. The optical feedback and winding arrangement support stable position tracking during repeated starts, reversals, and speed changes.
