A product that can operate the most of its designed lifetime consuming the minimum possible energy with high levels of productivity operating continuously without unplanned stops and with top performance, thus generating the maximum value to the user – this is what is behind W22 new concept.

Costs with energy correspond to approximately 90% of total operational costs throughout motor lifetime, being acquisition, installation and maintenance cost the other 10%. W22 new industrial motors platform are supplied with efficiencies meeting or exceeding NEMA Premium values, thus guaranteeing energy savings and reduced payback time.

In the 447T-586/7T range the new concept allows terminal box to be mounted top, right or left by using an extensor without disassembling the motor, therefore reducing modification time and inventory needs.

W22 motors are built using high quality cast iron at WEG own foundries, assuring maximum durability and high performance in aggressive conditions. The new fan cover design provides great resistance against impacts. Additionally the endshield have been designed for a better bearing heat dissipation.

The exclusive WISE insulation system used on the W22 range increases windings dielectrical resistance, thus allowing VFD operation up to 575V without requiring further modifi cation which results inflexibility and extended motor lifetime.

The W22 platform, offering high efficiency and low lifetime costs, will be the basis for further WEG developments. For example, as well as new permanent magnet motors and Exd motors, an Eco design of compact motors with optimised materials of construction are in development offering a reduced frame size per output. WEG is confident that the principles of the W22 design are the basis for a highly successful international class of electric motors.
