WEG W22 Severe Duty IEEE 841 Motor 75HP 8P 447T

The WEG 07509ER3E447T-W22 is a 75HP (55kW) 8-pole three-phase squirrel-cage induction motor from WEG's W22 Severe Duty IEEE 841 line, mounted on the 447T NEMA T-frame and rated for 875 RPM at 60Hz on a 230/460V supply. WEG is Brazil's largest motor manufacturer and one of the world's leading producers of electric motors and motion-control equipment, supplying more than 135 countries. Razz Middle East stocks the 07509ER3E447T-W22 in Saudi Arabia for fast supply to oil & gas, water, mining, cement and giga-project clients with SAR pricing and a 4-hour RFQ response. Engineered specifically for the corrosive, hazardous and high-vibration environments of oil & gas, petrochemical and pulp & paper plants, this Severe Duty variant adds enhanced sealing, corrosion-resistant coatings and IEEE 841 construction.

Technical Overview The 07509ER3E447T-W22 is built around a one-piece cast-iron frame that carries WEG's optimised W22 cooling geometry — a high-efficiency fan, ribbed housing and redesigned air-flow path that lower operating temperature and reduce audible noise compared with conventional NEMA motors. The stator uses premium electrical steel and a high slot-fill copper winding to cut I²R losses, giving the Severe Duty IEEE 841 efficiency rating of 95.4% at full load. Insulation is Class F (IEEE 841 / inverter-capable) with a conservative Class B temperature rise of 80 K, leaving thermal headroom for Saudi Arabia's high ambient temperatures. The IP56 enclosure, double V-ring shaft seals, epoxy paint and stainless nameplate protect the windings against dust, washdown and humidity. A NEMA Design B torque curve provides high locked-rotor and breakdown torque for direct-on-line starting, and the dynamically balanced rotor keeps vibration within the W22's low-vibration specification.

Performance & Specifications Rated output is 75HP (55kW) at 875 RPM with a full-load current of about 172.0A at 230V or 86.0A at 460V and a power factor near 0.74. The Severe Duty IEEE 841 efficiency of 95.4% meets or exceeds the NEMA MG-1 premium thresholds and the IEC 60034-30-1 IE3 class. A 1.15 service factor allows continuous 14% overload, and the motor is rated for continuous S1 duty from -20°C to +40°C ambient at up to 1000 metres altitude. Bearings are sealed and pre-lubricated for long maintenance intervals, and the frame is fully interchangeable to the NEMA 447T standard for drop-in replacement of legacy motors.

Applications in Saudi Arabia The 07509ER3E447T-W22 is specified across Saudi industry. In oil & gas it drives water-injection and transfer pumps at Saudi Aramco facilities in the Eastern Province, Abqaiq and Khurais, and at crude-handling terminals in Yanbu and Ras Tanura. In petrochemicals it powers process pumps, cooling-tower fans and extruders at SABIC and affiliated complexes in Jubail and Al-Jubail Industrial City. Water and utilities use it for high-lift and transmission pumping at SWCC and National Water Company stations around Riyadh, Dammam, Jeddah and Al-Ahsa. MAADEN mining and minerals operations apply it to crushers, mills and conveyor drives at Ras Al-Khair and Al-Jalamid, and the cement sector uses it on kiln fans, raw mills and packing lines. The NEOM, Red Sea and Qiddiya giga-projects deploy it across HVAC, water and infrastructure plant. Its premium efficiency directly supports the Saudi Energy Efficiency Center (SEEC) motor standards and the Kingdom's Vision 2030 industrial-energy targets.
