Product Description:

The AKM22E-BNMN2-00 is a compact AC synchronous servo motor manufactured by Kollmorgen and supplied within the AKM Synchronous Servo Motors series. It converts drive current from a digital servo amplifier into precise mechanical motion for indexing tables, miniature gantries, and other light-duty axes in automated machinery. By pairing its magnetic circuit with high-resolution feedback, the unit enables accurate position loops while maintaining a small mounting footprint, making it a common choice where cabinet space and cycle times are tightly constrained.

In drive integration, the motor uses an internal encoder that delivers 2048 lines/rev, allowing the controller to resolve position changes to fractions of a degree. This signal is generated by a Comcoder, a hybrid feedback element that combines incremental tracks with an absolute reference to simplify homing routines. The optical disc is a single-turn optical element, so multi-turn data are handled at the controller rather than inside the motor. The mechanical interface uses a NEMA flange, which aligns with standard North American bolt patterns, and the stator housing fits inside a 58 mm square frame for tight multi-axis assemblies. The feedback type is EPC 15T, and the unit ships in the standard customization level.

Torque density is influenced by the motor’s rotor length index 2, which uses a mid-length core to balance inertia and peak torque. Electrical constants correspond to winding designation E, so the matched Kollmorgen drive must supply the voltage and current required at rated speed. Output power is transmitted through a smooth shaft. This shaft style avoids keyway stress and supports clamp-style couplings on precision stages. For applications that rely on dynamic motor torque to hold position, the unit is supplied without a brake, so static loads must be managed externally.
