    • Bayonet connector (without mating plug)
  • Material / Construction:
    • Laminated silicon-steel stator core
    • Neodymium or ferrite permanent magnets (rotor)
    • Epoxy-coated windings (Class H)
  • Structural Features:
    • Square flange mounting (IEC-compatible)
    • Rear shaft for auxiliary encoder or brake option
  • Working Principle:
    • A brushless AC sinusoidal rotating magnetic field produced by the stator interacts with the permanent-magnet rotor; resolver provides real-time position feedback to the drive for commutation and control.
  • Installation Requirements:
    • Flange must be rigidly mounted to prevent misalignment
    • Use flexible coupling to minimize radial loads
    • Ground motor frame properly
  • Usage Notes:
    • Avoid exceeding Class H insulation temperature limits
    • Resolver wiring must be shielded and separated from power cables
    • Not recommended for new designs (legacy product)
