Ok maybe I already know this one but what is the meaning of a wet motor? to me if one gets wet they don't last very long afterwards but at the same time it also cuts down on a few things such as a large WTC in small areas..
I dont know if the 'wetmotor' concept is this one but I can tell you from experience that I have run motors completely out in the water and they have run WELL. I THINK if I recall that I used brushless motors but I cannot recall. I think you must. Then I have also used motors in solution in a sealed hull such that the motors and ALL the electronics were bathed fully in light machine oil. This is actually one of the techniques used to allow electronics packages and some mechanical assemblies to go full ocean depth on real submersibles. The light machine oil does not impede functionality of components that must move all that much and it is a good tradeoff on lifespan of components that otherwise would have to be in a pressure housing that could fail rendering them completely destroyed quickly. It is messy, it can leak, and it is a pain to maintain. But I HAD to try it and lo and behold it is quite wonderful. Of course you end up using MUCH flotation because you dont have airspace to have to weigh down.
Dont know if that is related but that is my take and experience with what I have called a wet motor assembly.
An old trick of electric car and plane buffs was to break in a new motor by running it emersed in distilled water. The water keeps the motor cool and lubricated until it is broken in. This usually prolongs the motor life while adding a couple hundred rpm. This works for brushed motors.
This was only done during break in. If you run a motor long term submersed in pond or pool water you will get hard water and salt deposits in the motor.
Contrary to most beliefs water is a great insulator and does not carry a current. It is the salts and ions in water is what allows it to carry a current.
