Fungus Proofing and Tropicalization of motor windings
Fungus Proofing and Tropicalization of motor windings
(OP)
Hello...
I ran a Search here at eng-tips and only came across a brief exchange of the above topic, without solution - in my case..
I am trying to learn more about the tropicalization methods / materials that one can apply to an electric motor. In this application (diesel-fired genset alternator) I have a gentleman who references his "tropical" as the "green stuff".. And he doesn't have a spec...
Can anyone make suggestions to a site or link where I can learn more about tropicalization? Pros & Cons?
Thanks very much,
Desmond

Tropicalizing that means:
50°C ambient, weatherproof per IEEE 45
'Tropicalized' motor option - electrical components are sealed against humid conditions
This refers to the resin used to coat the generator windings. Tropicalized windings are coated with a resin that protects the winding from adverse weather conditions and salt air.
Insulation: Mixture of epoxy resin and quartz powder makes the transformer nearly maintenance-free, moisture-proof, tropicalized, flame resistant...

The pros- can help control organic growth and is cheap and easy to apply. Simply mix the fungicide additive in with the varnish used to coat the windings.
The cons – It doesn't last all that long. Manufactures claim up to three years protection but I would be afraid to trust it more then a year in a rain forest area. Another thing is that after it is applied, since it is a paint additive, it is hard to see if there really is any protection there. So look for an additive that can be seen under a UV light [glows greenish-yellow which may be where your customer came up with "that green stuff"]so you can check adequacy of the coverage.
Try doing an internet search on paint additives to control mildew
