  • Continuous Stall Torque:​ 2.88 Nm (AKM33H base value)
  • Rated Torque @ speed:​ ~2.5 Nm at 5000 rpm, ~2.27 Nm at 2500 rpm (480 V class)
  • Peak Torque:​ 10.22 Nm
  • Rated Speed:​ Up to 6000 rpm (frame limit), typical 2500–5500 rpm depending on bus
  • Winding:​ C (240/480 VAC class)
  • Feedback (ACC2C):​ EnDat2.2 or SFD smart feedback, 24-bit class resolution
  • Brake:​ None (C option no brake)
  • Inertia:​ Higher than AKM31E due to H stack
  • Insulation:​ Class F, 100 K rise
  • Protection:​ IP40 base, IP65 optional
  • Connectors:​ M23 rotatable, dual-cable or single-cable SFD option
    Functional Features:​ High torque-per-volume, very low harmonic distortion, ±0.75 arc-min positioning class with high-res feedback, plug-and-play on AKD.
    Application Scenarios:​ Mid-power CNC feeds, robot joints, rotary indexing, labeling, filling valves, medical motion axes.
    Installation Requirements:​ Standard AKM3 flange bolt pattern; avoid shaft radial load > catalog limit; align coupling axially; use drive-enabled thermal cutoff.
    Usage Notes:​ ACC2C defines winding+feedback+connector combo; do not substitute resolver firmware if encoder expected.
