Detailed content

  • Technical Specifications (AKM6 family + 64K decode):
    • Frame:​ AKM6 (138 mm flange class)
    • Stack:​ 64 (long stack in AKM6 2/3/4/5 series)
    • Winding:​ K (high-torque, lower max speed)
    • Max bus voltage:​ 640 VDC
    • Stall torque (AKM6 family max):​ 25.0 Nm continuous
    • 64K typical stall:​ ~19–25 Nm class depending on exact winding table; peak ~44–65 Nm class
    • Rated speed:​ 6000 rpm max (K-winding often 3000–4500 rpm practical)
    • Rated power @ 640 VDC:​ up to 6.16 kW (AKM6 family max)
    • Shaft diameter:​ 32 mm (AKM6 standard)
    • Rotor inertia:​ ~0.0032 kg·m² class
    • Feedback:​ Integral resolver (NR)
    • Holding brake:​ None
    • Thermal:​ Class F insulation (155 °C), 100 °C rise over 40 °C ambient
    • Connector:​ Single/dual rotatable M23 Intercontec SpeedTec
    • Protection:​ IP54 standard (IP65/IP67 options exist in AKM family)
  • Functional Features:​ Exceptionally low cogging, best-in-class torque density, plug-and-play recognition on AKD®, full-frequency autotune, resolver for harsh-environment positioning.
  • Application Scenarios:​ Heavy CNC feed axes, printing press rollers, converting unwind/rewind, material-handling lifts, large rotary indexers, extruder aux drives.
  • Material & Structure:​ Aluminum motor housing, stainless-steel 32 mm shaft (smooth/keyed per order), NdFeB magnets, epoxy-impregnated copper windings, precision ball bearings both ends, resolver in rear cavity.
  • Working Principle:​ 3-phase PM synchronous rotation; resolver feeds rotor angle to AKD® for FOC; torque proportional to q-axis current.
  • Mounting Requirements:​ Flange pilot alignment, radial load limit several hundred N (AKM6 bearing set), foot or face mount; separate feedback and power cables with 2G shielding.
  • Usage Notes:​ Pair with Kollmorgen AKD-P01207 / AKD-P02407 at 480 V, or AKD-P01206 at 240 V with derate. No brake means vertical axis needs external mechanical hold. Resolver version needs AKD resolver commissioning routine. Derating above 40 °C ambient.
