W40 Line
Heavy Duty Motor
Reinforced three-phase motor built for continuous duty in demanding industrial environments — extending WEG's general purpose range into heavier applications.
Heavy DutyIP55220 – 690 V50/60 HzIE3
Overview
The W40 is built on a reinforced frame and cooling system designed for tougher operating conditions than the standard W22 line, without moving to extra-heavy-duty specifications.
It suits applications with higher ambient temperatures, dustier environments, or more demanding duty cycles, while keeping standard IEC mounting compatibility.
- Reinforced frame for tougher duty
- IP55 protection as standard
- Wide voltage compatibility
- Standard IEC mounting dimensions
- Genuine parts and factory-backed warranty via STM
