  • Technical Specifications:
    • Frame Size:​ AKM5 (~115 mm flange class)
    • Winding Code:​ M (mid-high voltage 400/480 VAC class)
    • Feedback:​ Encoder/resolver per suffix “NC21” configuration (closed-loop commutation)
    • Shaft:​ Smooth or keyed per standard AKM5 build
    • Max Bus Voltage:​ 640 VDC
    • Stall Torque:​ Approx. 14.1 Nm (AKM5 family max continuous stall)
    • Rated Speed:​ Up to 6000 RPM
    • Rated Power:​ Up to 3.87 kW at max bus
    • Inertia:​ Mid-inertia rotor for dynamic cyclic load
    • Protection:​ IP65 standard (IP67 washdown optional)
  • Functional Features:​ 155 °C class F insulation with 100 °C winding rise, single-cable SFD option, rotatable M23 connectors, optional 24 VDC fail-safe brake.
  • Application Scenarios:​ CNC axis drives, packaging machines, material handling, robotics mid-power joints.
  • Structure & Material:​ Aluminum housing, rare-earth permanent magnet rotor, stator with low-harmonic laminations.
