www.we.net W22 Efficiency and reliability for industry Hih performance with maximum enery efficiency is the oal of the new WEG electric motor. Hih efficiency and Low cost of Ownership throuhout the entire motor lifetime have been the basis for the W22 development. A desin created to maximize performance and enery savins. Lower total operational costs A product that can operate most of its desined lifetime consumin the minimum possible enery, with hih levels of reliability, eneratin the maximum value to the user this is what is behind W22 new concept. Inverter Duty applications The exclusive WISE insulation system used on the W22 increases windin dielectric resistance, thus allowin VFD operation up to 575V without requirin further modification, resultin in flexibility and extended motor lifetime. * Voltaes above 575 V, please contact our nearest sales office. Built to last W22 motors are built usin hih quality FC-200 cast iron from WEG s own foundries, assurin maximum durability and hih performance in aressive conditions. The new fan cover desin provides reat impact resistance. Additionally the endshields have been desined for a better bearin heat dissipation and structural riidity. Protected by our WEG coatins hih performance paint system capable of passin a 240hr ASTM 117B salt fo chamber test. NEMA 143T-587 and IEC 100-355M/L Rane extensions for the future Available as both NEMA and IEC standards. The W22 line, offerin hih efficiency and low lifetime costs, will be the basis for further WEG developments. W22, a new concept: Excellent cost benefit ratio Optimization of enery resources Updated electrical features Vibration level reduction Easier maintenance Enery savin Costs of enery correspond to approximately 90% of total operational costs throuhout a motors lifetime. Acquisition, installation and maintenance cost are the other 10%. W22 new industrial motor platform is available with NEMA Premium efficiencies, uaranteein enery savins and reduced payback time. 2

www.we.net Desin Details New coolin system Redesined to provide improved air flow throuh all motor frames keepin low operational temperatures and assurin reliability and extended lifetime. The aerodynamic desin of the fan cover increases effective airflow, thus minimizin losses due to the recirculation of air between fan and fan cover. The fan was desined to provide strenth and reduced noise level. Motor terminal box and eyebolts were repositioned on larer frames to allow better airflow. The new W22 coolin system also contributes to: Cooler bearin temperature extendin relubrication intervals. Lower Noise Level fulfillin the most demandin Health & Safety reulations. Lower Overall Operational Temperature resultin in loner life. Terminal box Increased internal space makin connections more accessible to the user resultin in an easier cable handlin and connection. Terminal box can be mounted on top, left or riht site of the motor usin the same frame on the 447T and larer motors. Top mountin is optional on smaller frames. 6
www.we.net Frame Motor feet are solid providin a more resistant structure aainst vibration. The frame desin has points that can be used as provisions for vibration sensors as a standard feature. Benefits from the new frame desin: Motor temperature reduction Eyebolts repositioned - easier handlin in the application. Provision for vibration sensors - frame and endshields with provisions 90 displaced accordin to maintenance technical recommendations. Easier and more reliable vibration analysis. Solid feet - Enhanced reliability when operatin on hih vibration applications and also provide easier alinment on installation. Exclusive bearin sealin system extends motor lifetime when operatin in aressive environments by protectin the motor aainst water and dust uaranteein proper deree of protection. 7
