WEG has launched the W22 Super Premium range of motors. The company claims that the electric motor is the only complete standard range available on the market worldwide that exceeds the yet-to-be-implemented IE4 regulations.
The W22 Super Premium performs across the full power range from 3 kW to 355 kW and WEG says that this presents up to 40% less losses compared to previous designs. The three-phase induction motor is based on WEG’s W22 motor mechanical design and is aimed at industrial applications including fans, blowers, pumps and compressors.
The motors feature an aerodynamic frame, redesigned cooling system and insulation system. Special bearing seals also extend the lifetime of the motor in aggressive environments by protecting it against the ingress of water and dust.
It has a flexible terminal box design for the 225 – 355 frame sizes, whereby the terminal can be positioned on the top or side to best suit the application. The W22 Super Premium range is modular, enabling a common motor frame to be used with different types and sizes of terminal boxes.
Suitable for low voltage supplies, the W22 Super Premium motor range covers 2, 4 and 6- pole motors in frame sizes up to 355.
