AKM2G-64N-ASSNAA02 by Kollmorgen

The AKM2G-64N-ASSNAA02 is a brushless servo motor manufactured by Kollmorgen for the AKM2G Magnetic Motors series. Designed for integration with matched drives, the unit converts controlled armature current into regulated mechanical motion for indexing tables, conveyors, and packaging axes. Its frameless magnetic design improves power density while retaining standard mounting features, allowing compact machine layouts without sacrificing dynamic performance. It can be used in systems where compact motor packaging helps preserve space for guarding, tooling, or adjacent axes.

Electrically, the motor produces a back electromotive force of 102 Vrms/kRPM, a value the drive uses to predict speed and establish commutation timing. The torque constant is 1.51 N-m/Arms, so each ampere of sinusoidal phase current produces about one and a half newton-meters of torque. Continuous operation is based on a phase current of 17.8 Arms; when this steady current flows through the 0.39-ohm line-to-line resistance, resistive losses remain within the stator's cooling capability. Dynamic control behavior is influenced by the winding inductance of 6.8 mH, and the magnetic circuit uses 10 poles, which affect electrical frequency and cogging behavior. These electrical characteristics support stable torque production as load conditions change during motion.

Mechanical output is characterized by a continuous stall torque of 26.8 N-m, allowing the motor to hold static loads at rated current without overheating. During acceleration or load disturbances, it can reach a peak stall capability of 70.3 N-m, giving headroom for short motion bursts before thermal limiting occurs. The rotor's reflected inertia is only 0.00169 kg-m², which supports quick speed reversals and short settling times in cyclic motion. Coupling is simplified by a 32 mm shaft diameter that matches common taper-lock hubs and belt pulleys. This shaft arrangement supports straightforward integration with couplings, timing pulleys, and similar transmission components.
