Detailed content

Typical Specifications (M-series DDR context):
  • Continuous Torque:​ ~5.3 – 339 Nm (series dependent; M-207 likely mid-range)
  • Peak Torque:​ Significantly higher (2–3× continuous)
  • Speed Range:​ Up to 500 rpm (typical for high-torque DDR)
  • Feedback:​ Multi-speed resolver or high-res encoder (optional <1 arcsec)
  • Protection:​ IP65/IP67 (housed) or open (frameless)
  • Built-in Thermostat:​ Yes, for thermal protection
    Features:
  • No couplings, belts, or gearboxes
  • Zero backlash, high stiffness
  • Single/Dual bearing designs available
    Structure:
  • Stator with epoxy potting, rotor with magnets, integrated feedback
  • Frameless version: stator/rotor only, no housing
    Working Principle:​ Direct electromagnetic coupling; rotor mounts directly to load, commutated via absolute/resolved feedback.
    Installation:
  • Precise air-gap alignment critical for frameless types
  • Use calibrated fixture for concentricity (<0.025 mm)
    Precautions:
  • Avoid metal debris near air gap during assembly
  • Ensure feedback cable separated from power lines
