Brian:
My dad motivated me to stay in High School by putting me to work on Sanitary Sewer Systems (there is an oxymoron) and I serviced some lift station pumps. We used transformer oil in them.
The engineer in your URL says "The lower efficiency carries about a 2% increase in overall energy costs." -- I'd like to see what that is based on, and does it pertain to low voltage motors too?
And the water well pumps are often compensated with plain water. They just use wire in the winding that still has the insolation and stainless steel and plastic guts, but again these are high voltage.
I suspect the efficiency may be really bad due to low voltage trying to cross through the oil. Perhapes I'll have to experiment on a smal DC motor to find the answer.
The next question would then be, does 500 psi change the resistance of the connection between the brush and commuter in and oil compensated 24 to 36 volt DC Motor? What do you think?
