I dont have the equipment to stamp the plates and then isolate them. Bert
P.s. Jim I googled for you. : Collossus 12kw outrunner liquid cooled!
I personally have better experience with cooling the whole motor lot stock and barrel in transformer oil.
There is a question raised over watercooled out runners : https://forums.offshoreelectrics.com...read.php?19027
Why are water cooled outrunners useless...
Jim if you are questioning my language, my apology. I speak a number of foreign languages, but all badly. (watercooled windings instead of watercooled outrunner )
