Kollmorgen AKM42G-ACCNDB00

Product Introduction:
The AKM42G is a medium-frame synchronous servo motor from Kollmorgen’s AKM series, optimized for high torque density and dynamic response. Winding “G” is a 240 V class winding. This specific suffix (ACCNDB00) typically indicates: Standard AKM4 flange, G winding, C—feedback (SFD Smart Feedback Device or incremental encoder depending on exact code), N—keyed shaft with standard seal, D—no holding brake (or brake omitted), B00—standard paint/connector (usually double M23 SpeedTec connectors, right-angle rotatable).

Detailed content

Performance Parameters (typical for AKM42G @ 240 V winding):
  • Stall Torque (T₀):​ 3.53 Nm (31.2 lb-in)
  • Rated (Continuous) Torque @ rated speed:​ ~2.35 Nm
  • Rated Speed:​ up to 6000 rpm (max mechanical speed)
  • Rated Power:​ 1.06 kW @ 320 VDC bus / 1.48 kW @ 640 VDC bus (~2 HP)
  • Continuous Current (at stall, 100°C ΔT):​ 4.8 A RMS
  • Peak Current:​ ~14.4 A RMS (short term)
  • Rotor Inertia:​ ~0.00015 kg·m²
  • Winding Resistance / Inductance:​ per AKM winding G datasheet (L-L ~X mH)
  • Max DC Bus Voltage:​ 640 VDC
  • Insulation Class:​ F (155 °C)
  • Shaft:​ 19 mm (0.75″) diameter, keyway
  • Flange:​ 84 × 84 mm (IECstandard mounting)
  • Connectors:​ 2 × M23 (power + feedback), angled rotatable
  • Protection:​ IP65 (shaft seal), IP54 (body typical)
  • Ambient Temp Range:​ 0 … +40 °C (with 100 °C winding rise)
  • Housing Material:​ Aluminum alloy, black painted
Construction & Principle:
Permanent magnet rotor with rare-earth magnets; stator three-phase windings driven by sinusoidal PWM from the servo drive. Feedback device (SFD or encoder) provides commutation and position info to the drive for field-oriented control (FOC).
Mounting Notes:​ Flange-mount with 4×M6 through-holes; ensure proper grounding via PE terminal; motor must be coupled to drive sized for ≥4.8 A continuous / 12–30 A peak depending on selected AKD.
Applications:​ CNC axis drives, robotic joints, printing rollers, packaging form-fill-seal stations, semiconductor handlers.
