Have you ever worked with that sort of thing?Dielectric oil...
Ihe only personal experience I recall was with large oil cooled alternators on highway coaches, as a bus maintenance mechanic 40 yrs ago. (so the technology is very old).I've been thinking about this.
Have you any experience of oil cooled DC motors?
I'm wondering if it could be oil filled, if the commutator + brushes would be ok in oil or if a seal would be required to keep those parts dry [that would be difficult].
What kind of oil? how full should such a motor be? what about froth, mechanical resistance?
That's interesting, thanks.the same oil as the Detroit Diesel engines, which in turn went thru the engine oil cooler
You have to realize there is very little second hand machinery available where I live; when something does come up, it's almost always completely worn out and massively overpriced.Electric motors have more torque at low rpm than at high rpm.
i would look at maybe a cushman type cart, or mining equipment.
