Slip Ring Induction Motor Rotor

  • Rotor Type: Wound rotor with three-phase distributed windings.
  • Slip Rings: Copper alloy slip rings with high conductivity and wear resistance.
  • Rotor Diameter Range: 80–800 mm (customizable).
  • Stack Height: 50–600 mm, depending on motor rating.
  • Performance: Delivers 2–3× higher starting torque compared to squirrel-cage rotors.
