PA Series – Động Cơ 3 Pha Vỏ Nhôm Hiệu Suất Cao (IE3)
PA Series – Premium Efficiency (IE3) 3 Phase Aluminium Induction Motor
ATT PA Series compromises of 3-phase, squirrel cage, IE3 premium efficiency (IEC 60034-30-1) motors in Aluminium frame. ATT PA series motors are all-purpose and highly efficient, making them well-suited for general application machines. A removable foot mount is integrated in PA Series motors as an additional feature to enhance its capability. It can be used for general purpose applications in machines as well as in areas which have weight limits due to lighter aluminium frames.
IE3 motors have very minimal losses, 10-15% lesser losses as compared to IE2 motors, giving you more energy and cost savings, even paying back the motor initial purchased cost in the long run when compared to using IE1 motors.
It can be also be utilised in a diverse range of industries like metallurgy, petroleum, cement and paper production, chemical, and especially for high duration and high capacity operations. Furthermore, the ATT PA series induction motor is suitable to use in various types of general used machinery like pumps, machine tools, fans, compressors, transportation, and a lot more. It can also be used in hazardous areas for oil, steel, chemical, and mining sectors.
Our PA series motors are compliant with Singapore’s Minimum Energy Performance Standards (MEPS) for motors in accordance with the Energy Conservation Act (ECA)
