Technical Specifications:
  • Frame: 120 mm flange
  • Stack: 5 (long body)
  • Voltage class: 400–480 VAC (640 VDC bus typical)
  • Rated power: approx. 3.8–4.5 kW
  • Rated torque: 14–16 Nm continuous
  • Peak torque: 40+ Nm
  • Rated speed: 3000 RPM (max 4500 RPM)
  • Feedback: resolver or Hiperface/EnDat optional depending on build
  • Brake: none unless specified
  • Protection: IP65 standard
  • Insulation: Class F
Features:
  • High continuous torque in compact 120 mm package
  • Low inertia variants available
  • Compatible with AKD, S700, SERVOSTAR drives
  • Optimized cooling by natural convection plus frame radiation
Working Principle:
Same vector-control synchronous motor principle as AKM. Higher pole count and larger lamination stack produce higher torque at moderate speed.
Materials & Construction:
  • Cast aluminum end caps, drawn steel stator shell
  • Sintered NdFeB magnets, epoxy encapsulated
  • Precision angular-contact bearing on shaft end for axial load
Installation Requirements:
  • Requires 120 mm pilot hole (95 mm or 100 mm PCD depending on flange)
  • Foot or face mount; torque reaction absorbed by frame bolts
  • Cable entry via rotatable connector or conduit adapter
Precautions:
  • Continuous stall current must be limited by drive setup
  • Ambient must not exceed 40 °C without derating
  • Brake (if fitted later) needs 24 VDC external supply with safe discharge
