WEG W22 450M4 IE2 Three-Phase Motor 400kW 4-Pole

WEG W22 450M4 IE2 Three-Phase Motor 400kW 4-Pole (model W22 450M4 IE2)

WEG is a global leader in electric motors and automation, operating in 135+ countries with manufacturing in Brazil, Germany, India, Mexico and China. WEG products are standard specification throughout Saudi Aramco, SABIC, MAADEN, SWCC and NEOM projects due to their compliance with IEC, SASO and SEEC standards.

The WEG W22 450M4 IE2 is a 400 kW 4-pole squirrel-cage induction motor on the market-leading W22 platform. Built on a robust cast-iron frame 450M mm with precision-balanced rotor, it delivers synchronous speed 1470 rpm at 50 Hz on the Saudi 380/415 V grid. The IE2 efficiency classification meets IEC 60034-30-1, and the IP55 (IP65 for Ex variant) enclosure withstands Saudi Arabia's dusty, high-humidity coastal and desert environments.

Technical specifications: Output 400 kW, Poles 4, Speed 1470 rpm (50 Hz), Frame 450M mm, Efficiency IE2, Voltage 380/415/660 V, Frequency 50 Hz, Insulation Class F, Temperature Rise Class B, Protection IP55, Duty S1, Ambient 40°C, Altitude ≤1000 m. The motor conforms to IEC 60034-1, IEC 60034-30, NEMA MG-1 equivalent performance, and SASO energy-efficiency requirements for the Saudi market.

Design features: The W22 platform incorporates WEG's optimised cooling geometry with a low-noise external fan and cast-iron housing for superior heat dissipation — particularly important in Saudi Arabia's ambient temperatures regularly exceeding 45°C. The oversized terminal box accepts cable entries from three directions, simplifying installation in MCC panels and field junction boxes. All mounting arrangements (B3, B5, B14, B35) are available without modification to the main dimensions, allowing direct replacement of competitor motors on existing frames.

Saudi Arabia industrial applications: The WEG W22 450M4 IE2 is specified for: pumps (centrifugal, submersible, booster), fans and blowers (FD, ID, cooling tower), compressors (rotary screw, reciprocating), conveyors and material handling, HVAC air handling units, mixers and agitators, crushers and mills, extruders and packaging machinery. Saudi Aramco uses WEG W22 motors across upstream production, gas processing, pipeline compression and downstream refinery motor loads. SABIC specifies them for petrochemical reactor drives, SWCC for desalination pump trains, MAADEN for mineral processing, and NEOM for utilities and manufacturing infrastructure.
