WEG Medium Voltage Motors

W22 Medium Voltage Motors – TEFC

Severe Duty

High performance with maximum energy efficiency is the goal of the new WEG electric motor. High efficiency and low cost of
ownership throughout the entire motor lifetime have been the basis for the W22 development. A design created to maximize
performance and energy savings.

Applications

Pumps, fans, crushers, conveyor belts, mills, centrifugal machines, presses, elevators, packaging equipment, grinders and more.
