Cheap SERIES(????) R/R : VRRPM3 from OMP

[duaneage]

Plug it in and go for a ride. If it is a series regulator, the stator cover should stay a lot colder, right?

Not if there is hot oil behind it. On a dry stator model you might detect a difference but not likely since it's bolted on to the engine.

I saw a substantial drop in both oil operating temperature and temperature as felt with the hand after switching to a SERIES R/R on my 1100ED. At least one other member that I can recall saw similar.

UPDATE; Wheat dog has confirmed a nominal 30 degF drop in operating temp for an 83 GS1100ED with 1166 kit after making this change over to the Compufire-Fire R/R

IF your power requirement at the time is minimal, such as a fully charged battery, not a large draw, etc.

At Higher RPM (>5K RPM) the generator is putting out too much so the SHUNT R/R's short the windings converting excess to heat. The SERIES produces heat in the stator but it is only what is required to supply the load not to shunt the power.

I would think any time except for the first few minutes after a start, it would have to result in cooler oil. I bet it does almost as much good for the oil temp as those lame oil coolers, without any chance of springing a leak... (Bending over for ensuing flames) Anyway I will buy a few of these as soon as anyone who knows about these things says for sure it is a true series regulator.

 

[posplayr]

Correct. But if the load is great, no shunting, both perform basically the same and at the same levels. It is when you do NOT have a "full" load that the differences become evident.

So will it result in a cooler running bike? Maybe. But not always.

Efficiency is always good, and from your explanations it should result in good longevity. But lower running temps might be an anecdotal effect, not a guaranteed result.

- JC

A correctly running and charging bike overcharges at higher rpm. U might have a flat batter but that is not proper. I fail to see how measured results(ie lower temp) could be interpreted as antidotal?

the after market stators (electrosport) are all powdercoated and they burn. That must take 500degf andf 250 oil to cool it. And I know my 1100 ran coler than it ever had

 

[posplayr]

Antidotal? Cute

Measured results under a certain set of conditions. Not necessarily unique or even uncommon conditions, but for sure not a guaranteed, continuous set of conditions.

(Don't worry, I'm not interested in joining the "battle" you have going about stator paper, just pointing out realistic expectations)

As tkent pointed out, it seems likely it may run cooler after the first few minutes. I'm assuming that's to account for topping off a good battery after cranking the starter. That's what I would think about, too.

But in reality, there are so many often changing factors, it would be hard to say "always" one way or the other. Battery charge, battery health, electrical connections conditions (also how they may change with load/heat), accessories loads, headlamp usage (high beam?), turn signals, brake lights, sitting in traffic, ambient temp, etc.

The Series r/r makes sense and can have a number of benefits, but it won't *always* make your bike run cooler *all* the time.

If there is excess power produced, it's more likely. But we don't want everyone to think a series r/r will result in an automatic 30 degree cooler bike, nor that kind of result will be constant. It may, it may not.

Don't think something is wrong because it doesn't and have realistic expectations.

BTW, I read the back and forth analysis on the charging system with great interest. I don't think I've missed any recently.

I could do without all the belittling in the threads, but you fellas are passionate about your "studies" and I'm used to filtering out the junk. So keep the info coming.

I'm waiting for the pulsed feedback loop that will return excess power back to the stator in a sequence that will return *torque* back to the shaft as a pseudo electric motor.

Or maybe a stator with each winding split in half that can be combined or separated depending upon charging need/signal from the r/r

Anecdotal; OK got the right word; And I got your meaning the first time regardless.

Measured results under a certain set of conditions. Not necessarily unique or even uncommon conditions, but for sure not a guaranteed, continuous set of conditions.

lets try this definition, I think it fits even better with what you are trying to say

http://en.wikipedia.org/wiki/Anecdotal_evidence

1) Evidence, which may itself be true and verifiable, used to deduce a conclusion which does not follow from it, usually by generalizing from an insufficient amount of evidence. For example "my grandfather smoked like a chimney and died healthy in a car crash at the age of 99" does not disprove the proposition that "smoking markedly increases the probability of cancer and heart disease at a relatively early age". In this case, the evidence may itself be true, but does not warrant the conclusion.
The term is often used in contrast to scientific evidence

OK I'll keep it simple, and on topic

BIG BIKES get HOT ; little bikes not so much.

My BIG BIKE and Wheatdog's BIG BIKE run substantially and noticable cooler with a SERIES R/R that they ever did with a SHUNT r/r.

Conclusion BIG BIKES run cooler with SERIES R/R's. Small bikes not so much; Dead batteries even much less.

There is no lack of scientific evidence unless you choose to ignore it.

Chill out, Dude. You're going to give yourself a stroke and the rest of us an ulcer

Thanks for the reco doc

Woof!

I love my 1100, and Suzukis in general, but this is an amazingly bad design when it can add 30deg to a 100hp motor.

I'm probably closer to 130+HP and everybody knows the left coast is hotter

I think I'll unhook my stator from the RR and see just how much cooler my bike runs without that stator heating things up. I mean, jeez, an internal combustion engine doesn't generate as much heat as a 250 watt stator on the side of the engine.

I guess series regulators are all that and so much more.

 

[duaneage]

Did you try waxing the bike? I knocked .0005 seconds off my 0-60 time with a fresh coat a turtle wax. I also put the magnet on the fuel line, that really got the front wheel off the ground. Takes alcohol out of the gas too.


I think it's time for a few tests, mythbusters style, on these claims of magic engine cooling with different RRs. Somehow it doesn't make sense that a stator would provide enough heat to raise a 1100cc engine 30 degrees above what combustion does . I suspect I'm not the only one smiling at claims that defy the laws of thermodynamics.

Stay tuned.

 

[duaneage]

It's not going to be easy but I'll get Kari Byron to check my oil temperature and look for excessive heat being produced. And then we'll start the bike.

Umm, may we please get back on topic?
I am interested in this R/R because I may need one soon. I find the price more in line with what I would expect from this type of product. I believe the CompuFire units are overpriced because they cater to Hardley owners and could care less about frugal GS owners. So if we find a series unit more in our price range it would benefit all of GSR, not just a few who choose to promote one type or another.

I'm planning to meet Dan (SaltyMonk) this weekend and do a quick test using my equipment.Will be quick just to see if it gives the characteristic stator signature when regulating.

Access to all the wires will be really easy... this will be a temp install so we won't be able to ride it but I doubt that's what you're after anyway as I assume your scope is not mobile!

I got duct tape, but ........................ no never mind :-#

 

[salty_monk]

I got cable ties too...

 

[koolaid_kid]

Let me see if I can dig up a really long extension cord...
But seriously, that is good news. If it matches (or approximates) the rather distinctive Compufire waveform it could be interesting.

 

[salty_monk]

It looks very similar to compufire in the pics...
