he W22X motors with ATEX/ IECEx certification are designed for high requirements of aggressive and explosion-prone areas. This type series is available as low, middle and high voltage variant.
For the power range of 0.12 up to 1400 kW low voltage motors with varying ignition protection types are used, that are suitable for the zones 1, 21, 2 and 22.
At more demanding applications, middle and high voltage motors of 90 up to 4500 kW for nearly all categories are deployed. The sizes 560 up to 710 are not designed in the usual fin-cooled design (IC411) but as pipe-cooled (IC511) Ex motors (see picture 2). WEG is also able to deliver explosion-protected motors up to 40 MW.
