painting enclosures of industrial electric motors

[Salah]

Hi all , I am new to this forum, just looking for your advice for industrial electric motors, my question is there any reference standards for painting the enclosures of industrial electric motors when needed as part of the PM. Appreciate your guidance and advice for any international references or best practices with recommended coating types and procedures.
Best Regards, Salah

When you say 'enclosure' do you refer to the body/frame of the motor itself or to a larger housing that the motor sits inside?

 

[Salah]

The enclosure which I am refering to is usually part of the motor (motor frame) and protects it from contaminants in the environment in which it is operating. As you know, the type of enclosures are categorized as either open or totally enclosed, and there are different types of enclosures within each category. Thank you

BS 1710 British Standard Pipe Marking - https://www.graphicproducts.com/articles/bs-1710-british-standard-pipe-marking/

The link deals with pipe work including conduit and trunking etc.

Years ago I've seen enclosures and actual motors painted in the same orange as the installation pipework.

I believe these are harmonised international colours so it would seem a safe bet to use.

Are you just wanting to play safe with your choice or is someone requesting a specific colour?

The motors which which we have in our facilities are lager motors, they are purchased with blue color as manufactured, we just need to repaint them with the same color. I need to know the guidelines and requirements to repaint them again following international standards.

Is this purely cosmetic or for a purpose such as corrosion prevention?

he' needs to get it right in saudi. if he cocks it up, 200 lashes.

 

[Salah]

let's say for corrosion prevention.

The colours of motors don't generally have any meaning unless the particular site has their own colour coding scheme.

I vaguely remember there are recommendations for manufacturers regarding coatings on motors from standards authorities like ASME but to the best of my knowledge there's no standards regarding repainting for maintenance purposes.
