encapsulation of winding for use on salt water
(OP)
I want to encapsulate a electrical winding to use in salt water....but i don´t know the kind of composite or resin i´ll need, could somebody help me, cause this is not my thing... i was worried about, the diference on the thermal exparsion, about cracking...cause stator is for class F isolation, and close to the windings is posible there´s hot spots....
Then, other question is about compatibility with the isolation used on the windings, i mean, is posible to use a composite that is good electrical isolation, and good for the use in salt water.... cause the motor will work submerged onto the sea.... somebody tell me about use DER 330 (Dow Plastics) that is an liquid epoxy resin...what do you think...
thanks in advance.

You will need to develop a technique to remove air bubbles and to keep the resin contained until it jells.
Sometimes carefully turning the object, sometimes some heat during cure, sometimes a mould and sometimes a vibrating mould can help.
It depends on complexity and shape of the part, how much excess you can tolerate how many you want to make and what facilities you have.

maybe we could do mould where we could add the epoxy...an then vibrate it...
what do you think about the name of the epoxy i´ll use?, and about the absorption of water??
