Kollmorgen AKM52K-SSS2S-06

  • Product Name:​ AKM™ Series AC Synchronous Servo Motor, Frame Size AKM52 (Flange 115 mm / 130 mm OD), Stack Length K (long), 480 V AC winding, resolver feedback, smooth shaft, no brake, M23 connector
  • Product Introduction:​ The AKM52 is a high-power-density permanent-magnet AC servo motor from Kollmorgen’s AKM family. The “K” stack length gives the highest continuous torque in the AKM5 frame. “SSS2S-06” decodes approximately to: Standard (S) flange/IEC tolerance, Smooth shaft (S), Single resolver feedback (S), 2 = standard seal, S = no brake, -06 = 480 V winding / specific connector orientation.

Detailed content

  • Typical Performance Parameters (AKM52K — 480 V winding):
    • Continuous (Stall) Torque (Tc):​ ≈ 8.6 N·m (76 lb-in)
    • Peak Torque (Tp):​ ≈ 24–27 N·m (depending on exact winding)
    • Rated Speed:​ 3000 RPM (typical for 480 V winding)
    • Max Speed:​ up to 4500–5000 RPM (depending on feedback and balancing)
    • Continuous Current (Ic):​ ≈ 7.5–9.0 A RMS (at 100 °C ΔT)
    • Peak Current (Ip):​ ≈ 21–25 A RMS (short duration)
    • Torque Constant (Kt):​ ≈ 1.1–1.2 N·m/A RMS
    • Back EMF Constant (Ke):​ ≈ 70–80 V/kRPM (line-line RMS)
    • Rotor Inertia:​ ≈ 0.011–0.013 kg·m²
    • Winding Voltage:​ 480 V AC (suitable for 320–640 V DC bus)
    • Feedback Device:​ Brushless resolver (standard on S-code)
    • Brake:​ None (S = no brake)
    • Shaft:​ Smooth (no keyway), diameter typically 22 mm or 24 mm (check drawing)
    • Connector:​ 2 × M23 (power + feedback), angled or straight per option
    • Ingress Protection:​ IP65 with shaft seal; IP54 without
    • Insulation Class:​ F (155 °C), windings rated at 100 °C temp rise over 40 °C ambient
    • Ambient Temp. Range:​ 0 … +40 °C (–20 °C storage)
    • Compliance:​ cURus, CE, RoHS
  • Features:​ Low cogging due to skewed magnets; optimized slot/pole combination; global voltage compatibility; direct mate to AKD / S700 / S600 series drives.
  • Applications:​ CNC machine tool axis, large packaging/form-fill-seal machines, converting equipment, robotics joints, material test stands.
  • Installation Notes:​ Use Kollmorgen-specified motor power cable (shielded twisted pair + PE); tighten M23 connectors to specified torque (typically 0.8–1.2 N·m); align load coupling to avoid axial thrust on motor bearing.
  • Cautions:​ Do not exceed max radial/axial shaft load; verify resolver wiring polarity during first power-up; if brake were fitted, it would require 24 V DC — this unit has none.
