Stator - does the oil cool it or damage it?

[joeadams]

Well yeah, ya got me there. :-) LOL I guess we could install chemical tanks on the GS. :-) :-) :-)

Arrrrr ya got me. LOL

Earl

My understanding is DC current cannot be generated. DC can only be rectified from AC.

DC power can be generated via chemical reaction.

Just bustin your chops a little. Its not often that I would be in a position to correct Earl.

STATOR OIL COOL

? FOR EARLFOR
IF YOU RELOCATE THE R/R TOWARDS THE FRONT OF THE BIKE WERE
IT GETS MORE DIRECT AIR GOING ACROSS IT WILL THAT HELP COOL IT DOWN AND LAST LONGER

thats where Harley puts them!
it would help.

Interesting Leon. Makes me wonder why then we use an AC system if we could generate DC which wouldnt require a rectifier.

Also, the last line of the paragraph seems to substantiate my first statement. "By adding a commutator, Pixii was able to convert the alternating current to direct current" Technically, DC current is not being generated. AC current is being generated and modified resulting in DC current. It seems that by that definition, we could say the GS charging system produces DC current since DC is the end result.



Earl

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.

the AC generator used has no brushes making it simple and cheep to manufacture.
that is why so many bikes still use ac generators with a separate rectifier mounted elseware.

Ah hell, talk about information overload! :?

Let me try to get a handle on this by summing up.

DC Generator - called a Dynamo by some although
some use the term dynamo to mean any generator.
Also used by some to refer to an AC generator with
commutator.

AC Generator - an AC Generator or a dynamo or an alternator

Alternator - used by some to refer to any AC generator
and by others to refer only to AC generators with moving
field coils.

Is that about right!?

So, if folk are using the words differently they will never
see eye to eye. Esp if one of the people won't admit
some use terms differently...

Now, I'm off to see if I can fix my Java install (complicated
because I'm testing some Java apps on this PC).

(Herself wanted me to wear a badge to work today saying
''yes it is cold, isn't it''.)

Xifer,

You might find this site interesting.

http://www.walter-fendt.de/ph11e/generator_e.htm

I can't see it Firefox crashes on that site - so does IE !

Appears I have a java problem.

Managed to clear my java problem with a manual reinstall,
that is an interesting applet - although I wish they included
a genuine DIRECT DC generator (or is it a dynamo).

Ahhh Haaaa! :-)

Re: Stator - does the oil cool it or damage it?

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

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) :-)

[earlfor]

Batteries dont generate anything. They are a storage tank. :-) :-) :-)

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