  • Rear shaft extension option available in variants.
  • Compatible with SERVOSTAR CD/S300/S600 drives.
Application Scenarios:
  • Electronic semiconductor manufacturing
  • High-speed pick-and-place machines
  • Medical equipment requiring rapid positioning
  • Small packaging machinery
Material Composition:
  • Stator:​ Copper windings with Class H insulation.
  • Rotor:​ Neodymium Iron Boron (NdFeB) rare-earth magnets.
  • Housing:​ Anodized aluminum alloy.
Structure & Working Principle:
Three-phase synchronous motor where the rotating magnetic field of the stator interacts with the permanent magnets on the rotor. Position is fed back via a brushless resolver.
Installation Requirements:
  • Flange mounting (standard industrial pattern).
  • Avoid radial loads exceeding specification on the shaft.
  • Align coupling carefully to prevent bearing damage.
Usage Precautions:
  • Do not operate beyond peak torque/time​ limits (thermal damage risk).
  • Ensure resolver wiring is shielded and grounded at one end.
  • Ambient temperature should not exceed insulation class limits.
