WE Series (IE2) 3 Phase Cast Iron Induction Motor

ATT WE Series compromises of 3-phase, squirrel cage, IE2 high efficiency (IEC 60034-30-1) motors in Cast Iron frame. ATT WE series motors are all-purpose and highly efficient, making them well-suited for general application machines. Our WE series induction motors are widely recognized by their optimum performance even in challenging work conditions.

Our WE Series motors are designed to meet and even exceed the requirements for energy efficiency such as European IE2, CEMEP-EU (EFF1), Australia (Level 1B) and GB18613-2006. It is ideal to use in pumps, compressors, fans, carpentry and other mechanical equipment.

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 WE 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.
