W22 37kW IE2 — WEG W22 IE2 Three-Phase Induction Motor
The WEG W22 IE2 Three-Phase Induction Motor is WEG's best-selling general-purpose induction motor platform, engineered to meet the IEC 60034-30-1 IE2 High Efficiency classification across the full power range from 0.37 kW to 355 kW. The W22 represents a clean-sheet design compared to its predecessor, with an aerodynamically optimised external cooling fan, a new frame geometry that reduces active material losses, and a low-noise precision-balanced rotor — delivering efficiency improvements of 2–4% over the previous generation while maintaining the same mounting footprint for direct replacement. In Saudi Arabia, the W22 IE2 is the standard motor specification for utility pumping, HVAC fans, industrial conveyors, and general machinery across every industrial sector, from petrochemical plants in Jubail to food factories in Riyadh's Second Industrial City.
The W22 IE2 motor is designed to IEC 60034-1 and manufactured in WEG's ISO 9001-certified Brazilian facilities with INMETRO quality certification. Frame construction is cast iron (IEC frames 71–355) for maximum mechanical rigidity and thermal mass, critical for duty types S1 through S9. The motor operates on 380/660 V or 400/690 V three-phase supplies, 50 Hz, with Class F insulation (Class B temperature rise) providing a 25°C thermal margin that extends bearing and winding life in Saudi Arabia's high-ambient-temperature environments. Protection class options span IP55 (standard) to IP65, and the motor can be ordered with F/B-class insulation, PT100 thermistors, space heaters, and double-shaft extensions for custom applications. Frame sizes are fully interchangeable with IEC 72-1, enabling direct replacement of other brands' motors without baseplate or coupling changes.
Saudi Arabia's industrial sector is increasingly subject to SEC's energy efficiency regulations and the SEEC (Saudi Energy Efficiency Centre) motor replacement programme, which incentivises replacement of IE1 motors with IE2 or higher efficiency class units. The W22 IE2's lower full-load losses reduce electricity bills at the 380 V, 50 Hz Saudi grid frequency and contribute to SEC-reported carbon intensity metrics for industrial facilities subject to National Transformation Programme reporting. ARAMCO, SABIC, and Ma'aden engineering standards require IE2-minimum efficiency for all new motor installations above 0.75 kW, making the W22 IE2 the default procurement choice for EPC contractors executing projects across the Eastern Province, Jubail Industrial City, and Yanbu.
Razz Middle East maintains stock of W22 IE2 motors in the most common frame sizes and power ratings from 0.37 kW to 75 kW, with larger sizes available on short factory-order lead times. All motors are supplied with IEC test certificates, conformity declarations, and efficiency class documentation supporting SASO clearance. We provide SAR-quoted pricing with delivery to any Saudi city within 3–5 working days from local stock. Our engineering team offers motor selection assistance, efficiency upgrade studies comparing IE1/IE2/IE3 lifecycle costs, and coordination of installation and commissioning support for replacement programmes.
