W22 – WEG SAFE AREA MOTOR
WEGINDO / PRODUCTS / ELECTRIC MOTORS / W22 SAFE AREA MOTOR

The WEG W22 Line Induction Motors is high efficiency machine coupled with low-cost ownership throughout the motor’s lifetime have been the basis for the W22 development. A design created to anticipate concepts in performance and energy savings.
Application:
The W22 Line is ideal for use in pumps, fans, compressors, conveyors, mills, and other heavy-duty industrial processes where efficiency, reliability, and performance are critical.
Key Characteristics of W22 Line:
– Lower total operational cost
A product that can operate most of its designed lifetime consuming the minimum possible energy, with high levels of reliability, generating the maximum value to the user
– Inverter duty application
The exclusive WISE insulation system used on the W22 increases winding dielectric resistance, thus allowing VFD operation up to 575V without requiring further modification, resulting in flexibility and extended motor lifetime.
– Built to last
W22 motors are built using high quality FC-200 cast iron from WEG‘s own foundries, assuring maximum durability and high performance in aggressive conditions. The new fan cover design provides great impact resistance. Additionally, the end shields have been designed for a better bearing heat dissipation and structural rigidity. Protected by our WEG coatings high performance paint system capable of passing a 240hr ASTM 117B salt fog chamber test.
– Range extension for the future
Available as both NEMA and IEC standards. The W22 line, offering high efficiency and low lifetime costs, will be the basis for further WEG developments.
– Energy saving
Costs of energy correspond to approximately 90% of total operational costs throughout a motor’s lifetime. Acquisition, installation and maintenance cost are the other 10%. W22 new industrial motor platform is available with NEMA Premium® efficiencies, guaranteeing energy savings and reduced payback time.

WISE® WEG Insulation System Evolution
The WEG, WISE® insulation system (WEG Insulation System Evolution) has resulted from using enhanced insulation materials during the production of the electric motor insulation.
The WISE® (WEG Insulation System Evolution) is an advanced motor insulation technology developed by WEG to enhance performance, particularly in demanding applications such as those using Variable Frequency Drives (VFDs) or Variable Speed Drives (VSDs).
