KOLLMORGEN AKM65N-ANC2R-00

Product Brief:​ The AKM65N is a medium-to-large frame (65 mm flange family, actual AKM6 = ~100–130 mm flange depending on region; N = specific stack/voltage winding) brushless servo motor with neodymium-iron-boron magnets delivering high continuous torque and peak overload capability. Designed for direct coupling with Kollmorgen S300/S400/AKD drives. The -ANC2R-00 option typically indicates: Standard winding, No brake, SFD Smart Feedback Device, Metric shaft with keyway, Standard seals, Straight connector (or flying leads), IP40 base rating.

Typical Technical Data (AKM65 / AKM6-frame reference values — verify exact winding):
  • Frame Size:​ AKM6 series (larger than AKM5; flange approx. 115–130 mm, check drawing)
  • Rated Power:​ ≈ 4.5 – 6.2 kW (depends on winding)
  • Rated Speed:​ 3000 rpm typical (max speed up to 4500–6000 rpm depending on winding)
  • Continuous Stall Torque (Tc):​ ≈ 20 – 25 Nm (typical for AKM6 stack 3–4)
  • Peak Torque (Tp):​ ≈ 60 – 65 Nm
  • Rotor Inertia:​ Low-to-medium inertia optimized for dynamic cycles
  • Voltage / Bus:​ 320 VDC bus (120/240 VAC windings) or 640 VDC bus (480 VAC windings) — depends on winding code “N”
  • Feedback:​ SFD (Smart Feedback Device) — 16+ million counts/rev resolution; also available with EnDat,Resolver,Hiperface
  • Brake:​ None (No brake = “-N-” in AKM code; “-B-” would indicate 24 VDC spring-applied brake)
  • Shaft:​ Metric with keyway (smooth or keyed per option), oil seal standard
  • Connector:​ Rotatable Intercontec connector or flying leads (per option)
  • Insulation Class:​ F (155 °C)
  • Protection Class:​ IP40 standard; IP65/IP67 washdown versions available in other options
  • Ambient Temp:​ 0 °C … +40 °C (some specs -20 to +55 °C storage)
  • Housing Material:​ Laminated steel stator, aluminum alloy housing, rare-earth magnets
  • Mounting:​ Flange-mounted, IM B5 (IEC 34-7)
Features & Benefits:
  • Industry-leading torque density — more torque in smaller package.
  • Negligible cogging due to skewed magnet design → smooth low-speed operation.
  • SFD feedback enables auto-ID and autotune with Kollmorgen drives.
  • Multiple stack lengths and winding voltages for optimal inertia matching.
Applications:​ Large packaging machines, CNC rotary axes, material conversion lines, injection molding auxiliary axes, heavy-duty pick-and-place, printing press roll drives.
Installation & Notes:
  • Align motor shaft with load coupling carefully to avoid side loads exceeding bearing limits.
  • Ground motor frame to panel/cabinet earth.
  • If equipped with brake (not this version), brake must be wired to 24 VDC supply with proper discharge resistor if needed.
  • Avoid prolonged operation above rated continuous current without adequate cooling/derating.
