BLDC Motor Core

  • Wide Size Range: Stator Ø 30–500 mm, Rotor Ø 20–480 mm.
  • Compact & Lightweight: Optimized lamination thickness reduces motor size while maintaining torque.
  • Low Noise Operation: Precision stacking ensures smooth electromagnetic rotation.
  • Surface Coating: Organic or inorganic insulation layers to prevent short-circuit loss.
  • Custom Design: Tailored dimensions and magnet slots for diverse BLDC configurations.
