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
