Product Description:

The AKM2G-64N-ASSNAA02 is an AC synchronous servo motor manufactured by Kollmorgen for the AKM2G Magnetic Motors series. Built for precision positioning and velocity control, it forms the mechanical core of packaging stations, pick-and-place heads, and coordinated gantry axes. Through a low-cogging stator and concentrated windings, the motor delivers smooth rotation that enhances part quality and overall machine throughput in industrial automation lines.

Electrical performance starts with a continuous stall torque of 26.8 N-m that is maintained at a phase current of 17.8 Arms. A torque constant of 1.51 N-m/Arms ties commanded current directly to output torque for straightforward current-loop tuning. The motor generates a back electromotive force of 102 Vrms/kRPM, a figure used when sizing the DC-link and determining regenerative voltage margins. Winding inductance of 6.8 mH dampens current ripple, allowing the inverter to issue rapid set-point changes without excessive harmonic distortion.

For short bursts, the drive can apply a peak stall torque of 70.3 N-m, providing headroom for rapid indexing or overcoming static friction. Dynamic response stems from a rotor inertia of 0.00169 kg-m², which lets the axis accelerate quickly while limiting overshoot. A shaft diameter of 32 mm offers a rigid mechanical interface for couplings or gear reducers, and phase-to-phase resistance of 0.39 ohms defines copper losses under sustained load. The motor employs a ten-pole layout that lowers electrical frequency for smoother low-speed motion.
