Product Description:

The AKM12E-BNMN2-02 is a servo motor produced by Kollmorgen and positioned within the AKM Synchronous Servo Motors series. It is intended for closed-loop motion tasks where rapid acceleration, deceleration, and precise positioning are required. Integrating with compatible servo drives, the motor converts electrical commands into rotational movement that synchronizes automated axes in pick-and-place modules, small conveyors, and laboratory equipment. Its compact format suits machines where accurate motion is needed but installation space is limited.

This model is supplied without a brake, so mechanical holding must be provided externally when the shaft must remain locked during power-off. Position feedback is generated by an incremental encoder that delivers 2048 lines/rev, a resolution that allows fine interpolated positioning by the drive controller. The sensing hardware is a Comcoder, combining optical tracks and Hall signals in a compact package. Within the encoder, the code wheel uses the EPC 15T pattern and is configured as a single turn optical device, so the drive can track shaft angle within each revolution and handle commutation signals correctly. These encoder features support stable feedback processing in compatible drive systems.

Mechanical adaptation to the machine frame follows a NEMA flange layout, so the motor bolts directly to standardized face-mount gearboxes or brackets. The square casing has a width of 40 mm, enabling installation in tight multi-axis clusters without interference. A smooth shaft is provided to mate with clamp couplers or precision pulleys, which helps avoid keyway-related stress during repeated reversals. The motor uses rotor length index 2, which corresponds to the second stack length in the 12 frame and supports a balance of torque output and inertia for lightly loaded axes.
