Detailed content

Technical Specifications:
  • Frame: AKM7 (frame 7, 142 mm flange class)
  • Stack: L (long)
  • Winding: K
  • Rated Power: Approx. 5.5–7.7 kW (depends on bus)
  • Rated Torque: 25–35 Nm
  • Stall Torque: 53 Nm
  • Rated Speed: 2000–3500 rpm
  • Max Bus: 640 VDC
  • Feedback: Resolver (R code)
  • Shaft: Smooth, no keyway (KK = smooth shaft, C = no seal option dependent)
  • Brake: None
  • Connectors: M23 Speed Tec

    Functional Features:​ Best-in-class torque density, low cogging, plug-and-play with AKD, resolver for rugged use.
    Construction / Materials:​ Laminated stator, NdFeB rotor, aluminum housing, sealed bearings.
    Working Principle:​ Same synchronous BLDC principle as AKM53K with higher thermal mass.
    Mounting Requirements:​ Flange mount on gearbox or direct load; smooth shaft requires shrink-disc or zero-backlash collar.
    Usage Notes:​ Smooth shaft cannot transmit torque via keyway. No brake means load must be self-holding.
