W22 Super Premium Efficiency IE4 Electric Motors

  • Description

    In the last two decades global energy consumption has increased more then 50%, this increasing demand for electric energy to sustain global development requires constant investment in power supply generation.
    One of the main reasons for the global increase in power consumption is the industrial sector: the electric motor represents more than 40% of the total energy consumed globally.
    Due to this increase it is more important now that products are manufactured with energy efficiency as the main driver. Aware and concerned about this situation, several Governments are implementing Minimum Energy Efficiency Performance Standards in order to drive the use of highefficient equipment.
    With this situation in mind WEG presents its W22 Super Premium Efficiency motor line, exceeding the IE4 Efficiency Levels defined in IEC Technical Specification IEC/TS 60034-31 and draft IEC Standard 60034-30 edition 2.
    High overall performance which is translated into a lower Total Cost of Ownership, due to its reliability, easy maintenance and energy savings!
