The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

in a generator the magnets are fixed and the windings (stator) spin the commutator is the contact rings that brushes ride on, brushes don't take well to being imersed in oil, they also wear, and generators don't work well being spun at 9K RPM.

Someone said to me that running in hot oil damages the stator
whereas I thought the oil cooled it!

Is that true?

i wonder if this statement is someone confusing the fact that the gs rotor can be damaged if it overheats due to low engine oil levels?
 
stator

stator

The stator is only in oil because the starter clutch needs to be lubed, If you remember the very first Honda's they had a dry stator and the starter clutch assmembly needed to be repacked once in a while, the early dry stators rarly went bad and did not have the heavy epoxy coating on them so they shed heat better, if you have ever seen a belt drive triumph that still uses the oil bath type stator,( thick epoxy coat) but is now in a dry housing for a belt drive, they have no problems,

I dont believe there is any such thing as a DC generator or alternator.
My understanding is DC current cannot be generated. DC can only be rectified from AC.

My battery put out direct current (DC) :-)
 
Batteries dont generate anything. They are a storage tank. :-) :-) :-)

So, the oil is damaging not/and cooling the stator?
