AKM2G-63M-ANCNAB10 by Kollmorgen

The AKM2G-63M-ANCNAB10 is a permanent-magnet synchronous motor developed by Kollmorgen within the AKM2G Magnetic Motors series. This frame-size 63 unit serves as the rotary actuator in servo loops where closed-loop drives impose fast position or speed changes on mechanical loads. By delivering controllable torque from a compact housing, the motor links the electronic output of a servo amplifier to conveyors, pick-and-place heads, or indexing tables found across automated production cells. Its compact format also suits applications that need high torque density without adding unnecessary bulk to moving assemblies.

Under continuous conditions it can sustain 21.4 N-m of stall torque while drawing 15.2 Arms. That steady performance stems from a copper resistance of 0.49 ? at 25 °C and a line-to-line inductance of 8.2 mH, both of which influence current rise and heat generation. The winding geometry delivers a torque constant of 1.41 N-m/Arms, meaning each ampere produces predictable drive torque, and a back-EMF constant of 95.5 Vrms/kRPM that the drive must counteract during high-speed operation. Ten rotor poles create the electromagnetic field pattern, and the 32 mm shaft transmits torque to couplings or gearheads without additional adapters. Static friction is limited to 0.06 N-m, while viscous damping equals 0.053 N-m/kRPM, so servo tuning can achieve tight velocity regulation without excessive gain.

For transient moves the motor tolerates 45.5 Arms of peak current and produces a maximum torque of 54.5 N-m. Dynamic reversals are helped by a rotor inertia of only 0.0013 kg-m², allowing rapid acceleration while still providing enough mass to smooth low-speed ripple. Thermal behavior is managed through a resistance of 0.393 °C/W and a time constant of 50 min, giving the housing time to shed heat before internal temperatures climb. Low friction at the shaft helps the control loop respond cleanly during small corrective moves, especially in applications with repeated starts, stops, and reversals. The thermal response also helps limit temperature rise during demanding motion cycles.
