WEG W22 IE3 Premium Efficiency Three-Phase Motor

The WEG W22 IE3 Premium Efficiency Three-Phase Motor delivers IEC 60034-30-1 IE3 Premium Efficiency across the power range from 0.75 kW to 355 kW, occupying the efficiency tier above the IE2 standard and now mandated or strongly incentivised in most major Saudi industrial procurement specifications. Built on the same W22 platform as the IE2 variant — same outer frame dimensions, same mounting pattern, same terminal box position — the IE3 upgrade requires no mechanical modification to existing installations, making motor replacement or new installation interchangeable at zero extra installation cost. The W22 IE3 achieves its superior efficiency through a combination of improved copper fill in the stator winding, a longer active core, optimised rotor slot geometry, and premium-grade silicon steel laminations, all contributing to measured full-load efficiency improvements of 1.5–3% over IE2 equivalent motors.

The W22 IE3 motor is manufactured to IEC 60034-1 with IE3 efficiency values verified by accredited third-party test laboratories and documented in the motor test certificate supplied with every unit. The thermal design uses Class F insulation with Class B temperature rise (identical to the IE2), maintaining the same 25°C thermal margin over Saudi Arabia's 50°C design ambient. Available in IP55 (standard) and IP65 (optional) enclosures with cast iron frames for all IEC frame sizes from 80 to 355. For variable-speed drive applications — which constitute the majority of new motor installations in Saudi industrial projects — the W22 IE3 carries an inverter-duty rating compliant with IEC 60034-17 and IEC 60034-25, ensuring reliable insulation performance under PWM voltage stress from modern VFD outputs without additional motor protection filters in most cases.

The IE3 premium efficiency motor has become the de facto standard for new motor installations across ARAMCO, SABIC, Saudi Aramco Total Refining and Petrochemical Company (SATORP), and Ma'aden engineering procurement specifications, driven by both corporate sustainability targets and SEEC programme incentives. Under Saudi Arabia's Vision 2030 energy efficiency agenda, SEEC offers rebates for replacing IE1 and substandard motors with IE3 or better units, creating a systematic replacement programme that generates sustained demand for IE3 motors. The W22 IE3's combination of proven Brazilian manufacturing quality, competitive landed cost in SAR versus European alternatives, and Razz Middle East's local stocking service makes it the preferred choice for Saudi engineering procurement managers comparing total cost of ownership.

Razz Middle East stocks W22 IE3 motors from 0.75 kW to 90 kW across standard two-pole, four-pole, and six-pole speed versions, with less common pole counts and above-90 kW ratings available on factory-order lead times of 4–8 weeks depending on frame size. All units are supplied with IE3 efficiency certificates, CE declarations, and IEC 60034-1 test sheets. SAR pricing with VAT is provided within four hours of enquiry. Our engineering team offers full lifecycle cost comparisons between IE2 and IE3 options — typically demonstrating IE3 payback periods of 12–24 months in continuous-duty applications — supporting Saudi customers' capital expenditure justification to CAPEX approval committees.
