RE: Flameproof motor?
It is common to see a variety of different colours for Ex motors - From memory I can think of examples of green, grey, orange and blue.
ABB's standard colour is blue:

as are Brooks

So it is very common to see Ex blue motors
RE: Flameproof motor?
many thanks for detailed reply
we had a customer who had their rig painted white over the EExd motor, the inspector now says it will not pass Atex inspection, invalidating flame paths ect..
RE: Flameproof motor?
There are quite a few ways to invalidate the EX compliance as well, doing maintenance on motors outside an accredited EX shop is a good one.
RE: Flameproof motor?
There is no colour code for explosion proof Motors
Thanks,

The inspector is incorrect regarding a requirement for the colour to be blue, but probably is correct regarding painting over flamepaths unless it has been done with care.

Painting over the whole motor enclosure of any color will not restrict to pass ATEX inspection. No industry codes and standards that will restrict you to use any color of the paint.
The ambient air of the atmosphere will affect the temperature classification of the motor, NOT the paint.
