Super Premium Efficiency (IE4) Achieved!!

– Characteristics test of 3-phase induction motor using copper rotors die-cast by Castman
– Certification Agency : Gyeongnam Technopark

  • Advantage of using copper die-cast rotors
    •  Downsizing of motors
      • Application of IE3, IE4 rotors in IE2 rotor-based motor frames
    • Low heating due to operation :
      • Reduction of electrical resistance due to relatively higher electrical conductivity of pure copper compared to aluminum
      • Reduction of average motor internal operating temperature by 15 degrees
  •  High Reliability
    • Stable operation in frequent On/Off operations and in highly corrosive environments
