2 ATT WE series (Eff1) are 3-phase TEFC Cast-Iron high efficiency general purpose induction motors, which are designed to meet or exceed the requirements for energy efficiency such as: European Eff1, Australia level 1B, Cemp-eu (eff 1), SS530 and GB These motors are also built to comply with the requirements for European CE marking and International Electrotechnical Commission IEC ( included , , , , , , and ). Compliance with IEC60034 means that these motors also complies with many standards from other countries that are based on IEC Features of WE series motors include : European design, better structure with high strength ragged cast iron frames, Removable feet with more suitable for the application of petroleum, chemical, metallurgy, cement and parper industries, especially suitable for the long time and at full capcity operation of the fans, pumps & compressors etc. Standard Specification: Item Standard Specifications Type of Motor Totally-enclosed fan-cooled squirrel cage induction motor Time duty Maximum continuous rating, S1 duty Cooling method Self external fan, Cooling design IEC 34-6, IC 411 Method of starting Full voltage direct on line starting or star-delta starting Mounting Horizontal foot mounting, flange mounting : B3; B5; B14; B34; B35; V1 Insulation class & Adopting class F insulation and checking permissible limits of temperature rise Temperature rise against that of class B to improve the insulation reliability Rotor winding Squirrel cage, aluminium conductor with end-ring and wafter blades integrally cast Drive method Direct, unless otherwise specified Direction of rotation Bi-directional, Direction of rotation of motor can be reversed by interchanging any two of the power lines Test procedure IEC , GB/T1032 efficiency by summation of losses method Shaft Carbon steel, round shaft with key Bearing Grease pre-packed shielded ball bearing Lubrication Lithium-base grease (shell Alvania R3) Painting Phenolic rust-proof base plus lacquer surface finish; Painting in Green Nameplate Stainless steel Grounding terminal NE set inside the terminal box Fan Polypropylene plastic Balancing Executed with half sized key IEC ISO 8821 Environmental Place : Non-hazardous conditions Standard Ambient temperature : -20 C to 40 C Relative Humidity: Less than 90% RH (non-condensation) Altitude: less than 1000 metres above sea level

8 Voltage / Frequency Standard voltages and frequencies are V / V at 50Hz for 2.2kW and below, V / V at 50Hz for 3kW and above, and other voltages such as V, V at 60Hz. Voltage tolerance is ±5% and frequency tolerance is 1%. Voltage beyond these limits will cause a high winding temperature rise. Other voltages can be made on request. Connection/Method of Starting The standard terminal connection for 2.2kW and below is volt delta / volt star. These motors are normally connected in star connection and suitable for Direct-On-Line starting. For motors 3kW and above, the standard terminal connection is volt delta / volt star and suitable for both autotransformer and star-delta starting. A.
