W22 Line
The global reference in three-phase induction motors — engineered by WEG for high efficiency, robustness and reliability across general industrial applications, from pumps to conveyors.
Overview
The W22 is WEG's flagship general-purpose motor line, built on a modernized platform that improves efficiency, thermal performance and acoustic behavior compared to previous generations.
Its cast-iron frame and optimized cooling design make it suitable for continuous duty (S1) across a wide range of industrial applications, while remaining compatible with standard IEC mounting dimensions for straightforward replacement of existing motors.
- IE3 Premium Efficiency as standard, IE2 available
- Robust cast-iron frame, sizes 63–355
- IP55 protection as standard
- Compatible with standard IEC mounting dimensions
- Genuine parts and factory-backed warranty via STM
