WEG W22 High Efficiency Motor – Frame 280S/M-04

The WEG W22 High Efficiency Motor, model 280S/M-04, is an industrial-grade, three-phase asynchronous motor built to meet the demands of continuous-duty (S1) applications. This motor is part of WEG’s renowned W22 series, known for its rugged construction, energy efficiency, and extended service life.

With IP55 ingress protection, Class F insulation, and IC411 (TEFC) cooling, the motor performs reliably even in challenging environments. The frame size 280S/M-04 supports various industrial load conditions, and its B3 foot-mounted configuration ensures ease of installation.

The motor features 6316-C3 bearings on both drive and non-drive ends, lubricated with Mobil Polyrex EM grease for low-friction operation and long service life. Its shaft is crafted from high-strength steel for improved torsional stability under load.

Although the exact power output is not specified, the W22 line typically ranges from 75 kW to 110 kW for this frame size. It supports Direct-On-Line (DOL) or Star-Delta starting, and conforms to IEC 60034 and IEC 60072 manufacturing and testing standards. It meets IE2 or better energy efficiency standards and carries CE, UL, and CSA certifications for global use.
