Product Brief:
The AKM72P-ANCNDAO is a Kollmorgen AKM72P frame servo motor with an integrated absolute encoder. The suffix breaks down as: A = AKM series, N = absolute encoder (EnDat 2.2), C = smooth shaft with keyway, N = no holding brake, D = specific winding variant, A = connector type (M12), O = optimized for velocity applications.

Material Composition:

  • Stator: 0.2 mm silicon steel laminations, Class H copper windings
  • Rotor: Sintered NdFeB, N42UH grade (high-temperature rated)
  • Housing: Anodized aluminum alloy (6061-T6), black
  • Shaft: Hardened stainless steel (AISI 440C), ground to h6
  • Bearings: Sealed angular contact ball bearings (lubricated for life, 20,000 hours L10)

Functional Features:

  • Integrated absolute encoder — zero homing required after power loss
  • M12 connector — single-cable connection for power and feedback (reduces wiring complexity by 50%)
  • Class H insulation — allows 10 °C higher continuous operation than Class F motors
  • No brake — lighter weight, faster acceleration (brake not needed in vertical-axis or belt-driven applications)
  • Optimized for velocity — low cogging, high smoothness at constant speed

Applicable Industries:

  • High-speed pick-and-place
  • Semiconductor transport modules
  • Medical lab automation
  • Printing and converting
  • Textile machinery (yarn guides, tensioners)

Installation Requirements:

  • Mount using 4× M5 bolts on Ø95 mm bolt circle
  • Shaft alignment: ≤ 0.03 mm TIR
  • Use M12 connector — do not cut or splice the cable
  • Maximum radial load: 150 N; axial load: 80 N

Usage Notes:

  • The “O” suffix indicates velocity-optimized winding — do not use for high-torque, low-speed applications
  • Class H insulation permits continuous operation at 155 °C winding temperature (vs. 130 °C for Class F)
