Copper Die Casted Rotor

  • Superior Conductivity: Copper’s 58 MS/m conductivity boosts motor efficiency by 15–20% over aluminum rotors.
  • Lower Rotor Resistance: Reduces I²R loss, improving torque output and reducing operational temperature.
  • Precision Casting Quality: Vacuum or high-pressure die-casting ensures full slot fill with minimal porosity.
  • Enhanced Motor Efficiency: Enables IE4 and IE5 class performance in industrial applications.
  • Eco-Friendly & Recyclable: 100% copper rotor reduces lifecycle carbon footprint.
