WEG W22 450S 315kW 6-Pole IE3 Motor

The WEG W22 450S 315kW 6-Pole IE3 motor provides the highest-torque LV motor solution for 985 RPM applications in the Saudi and GCC industrial market, delivering 3050 Nm of continuous shaft torque suitable for direct coupling to the largest centrifugal pumps, cooling tower fan drives, and industrial fan applications without intermediate speed reduction.

The 450S 6-pole configuration is particularly valued in Saudi Aramco's water injection programs where very large booster pump stations require motors in the 300–400kW range operating at 985 RPM. The direct-drive configuration eliminates gearbox oil systems, gearbox maintenance, and gearbox failure modes from the reliability equation—an important consideration for remote desert locations like Haradh, Khurais, and Shaybah where maintenance access is costly and logistics-intensive.

Cooling system design for the W22 450S represents WEG's engineering evolution at large frame sizes. The external cooling fan is precisely sized and positioned to deliver optimal airflow through the fin array, maintaining acceptable temperature rise even at ambient temperatures up to 55°C. Motor surface temperature at full load, ambient 45°C, is maintained below 85°C on external frame surfaces—safe for personnel contact protection and satisfying Saudi SASO standards for touch temperature limits on rotating machinery.

The W22 450S 315kW 6P is compatible with WEG's full range of variable speed drives for applications where process optimization requires speed variation. At this power level, WEG offers the CFW700A and CFW11 drive series, both of which are available through Razz Middle East in standard and hazardous area versions. The complete motor-drive package with common WEG sourcing simplifies commissioning, optimizes electrical compatibility, and consolidates after-sales support responsibilities.

For industrial utility systems at Saudi industrial cities, the W22 450S drives large cooling water circulation pumps that serve multiple process plants within an industrial complex. In these shared utility configurations, motor availability directly impacts multiple production units, making reliability the dominant selection criterion. WEG's global field failure data for the W22 series demonstrates mean time between failure (MTBF) exceeding 10 years in properly maintained installations—a reliability level that supports asset management strategies based on condition monitoring rather than time-based replacement.

The motor nameplate information for the W22 450S complies with IEC 60034-1 requirements and includes all data required by Saudi Aramco's inspection department and SASO electrical product certification requirements. Nameplates are manufactured from stainless steel with laser engraving to ensure permanent readability in industrial environments where conventional painted nameplates may become illegible through abrasion, chemical exposure, or UV degradation.
