Three-Phase : W21 TEFC (IP55) - Ball Bearings - High Efficiency

WEG's W21™ Severe Duty High Efficiency motors are designed to meet or exceed all EPAct requirements for energy efficiency as defined by the DOE. The efficiency values are certified according to the DOE's regulations (Certificate of Compliance number CC029A).

W21™ motors meet the most demanding severe duty application requirements. These TEFC motors are all cast iron construction, with enclosures rated IP55 to handle wet and dirty environments. They are painted with WEG's own special system, using synthetic enamel alkyd resin paints, which exceed the ASTM B117 standard for salt spray test. The W21™ line is rated for 1.25 Service Factor up to 100HP and meet Design B (up to 100HP) and Design C (from 15HP up to 100HP) torque requirements. This line is rated for dual frequency and dual voltage (with reduced service factor) up to 60 HP. And the entire line is certified Inverter Rated for use with a VFD. This rating meets or exceeds MG1 Part 31 NEMA Specifications.
