WEG W21 and W22 three-phase industrial electric motors

WEG W21

Multi-mount aluminum casing for European market

WEG W21 aluminum motors are recognized for their excellent quality, reliability and efficiency, offering the same benefits as the robust cast iron range, but with a lightweight construction and a design that provides unmatched flexibility, as the terminal box can be positioned at the top or on both sides, with the possibility of rotating it in 90° steps to facilitate the connection of the power cables in any position. This unique system eliminates the need for mechanical modifications to the motor feet, greatly simplifying installation.

Furthermore, the innovative design of this range offers the added benefit of standardization and flexibility in stock, allowing the use of a single motor for different mounting configurations and ensuring full interchangeability with existing cast iron motors.

Complementing the wide range of industrial motors, the W21 series also offers specific designs for defined applications. In addition to the standard multi-mounting version, brake motors, single-phase motors, marine motors and TEAO motors (IC 418) for ventilation and exhaust gas applications are available. These specialized versions adapt perfectly to all application needs, maintaining the same reliability, ease of maintenance, reduced energy consumption and flexibility.
