Permanent Magnet Motor Rotor

  • Material Selection: Silicon steel, cobalt alloy, or nickel-based lamination for performance optimization.
  • Magnet Integration Options: Surface-mounted, interior (IPM), or V-shape configurations.
  • High Torque Density: Achieves up to 30% more torque than induction rotors at the same size.
  • Magnetic Efficiency: Flux density ≥ 1.8 T ensures strong and consistent torque output.
  • Corrosion Protection: Anti-oxidation coating on both laminations and magnets for durability.
