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
- Downsizing of motors
- High Reliability
- Stable operation in frequent On/Off operations and in highly corrosive environments
