Topic: Stator burn out cause Posted: 17 Sep 2018 at 22:42
we all know our bikes have a tendency to fire out the charging systems and we know why, merely in real terms why ???
Now I sympathise how the organization works but I tin can't empathise why with regulator and a stat and other bits to stop information technology burning itself out it really does. I tin't recollect a auto that suffered with these bug. I know that it seems to put out besides much current but why don't the bits that control information technology practise and then
Is at that place any tech guys on here that tin break it down simply for marvel

And to stiff as u say that's why but replacing stater or rewinding doesn't seem to work for long.faulty parts if u enquire me.

Post Options Cheers(0) QuoteReply Posted: 17 Sep 2018 at 23:27lots of discussion on this over numerous threads. Aprilia released a kit that appears to take fabricated the biggest departure at a cost of close to 1k iirc, which is a flywheel and stator kit. Different strength magnets? Something like that, to be honest it gets confusing reading nigh it all. Much of it is theory rapidly resulting in those interested in electronics, ripping a quality wheel apart and advising others to do the same going back to brown connectors etc.
Some say the charging system, or in item the reg/rec is a blazon that dumps backlog voltage in such a way the stator gets hot. Some say the stator is insufficiently cooled by the oil in the crankcase. Aprilia say it's because the magnets are too strong hence the eventual redesign.
I for one am not ripping my loom autonomously considering of one or two guys baffling theory on electronics, I'll only chusck another stator in if required, but what I'll practise showtime, is continue to expect later my dainty bike/s in that I regularly remove the fairings to clean it and all the connectors, one of which is the brown one near the reg/rec that gets corroded existence at the front of the bike, and becomes a poor connection, which then overheats. Clean and care for it regularly and all the other points, and it'll terminal longer.
I've owned these bikes for fourteen years and changed one stator 2 years ago. My blood brother know owns i, and has washed about a m miles in the last three weeks, and he called me yesterday with a symptom which could be i of a few things, the stator being one of them, and so I need to get to see it.
Sorry if this wasn't the reply you sought, but I urge y'all to resist the temptation to chop out connectors or wire in reg/recs of different designs unless totally convinced of the reason to do it, and make a log of what the changes are for the adjacent owner which is a big part of furure issues. Owners take fiddling idea until something fails, that stuff has been dicked about with.
And so but my2p, in conclusion, I'll stick with Aprilia, and say it'due south the flywheel every bit the root cause. Everything else is near symptom control ;O)

i. is the bikes that re fire out stators on a regular footing = Flywheel
two. Those that kill ane every 10 years or and so.
The latter is just the symptom of a 500w stator beingness driven flat out for 10 years. Although there is a regulator, it only regulates the output to the battery via a shunt. The stator runs at 100% at 100% of the time for any given revs and the excess is simply shunted abroad as heat.
You could liken it to revving your bike to the redline and controlling your speed with the clutch. It'll work but only for so long.
If your bike is regularly killing stators, fit the 380w stator kit. If it's on a ten yr or so cycle, only fit a rewind for £100 and get another ten years. People throw £150 at a new rear tyre every 3k miles and don't bat an eyelid at it, information technology'south not such a big deal every bit some of the internet trolls similar to make out.

I had a rewind washed at the start of the season and its been fine since.

I am wondering if this was cartoon off the excess ability and saving the stator to some extent as information technology has vertainly done information technology no impairment at all .
Burning out a fix of hot grips is a whole lot cheaper than the replacement startor and Flywheel combo.

Adding load prevents some of the excess existence shunted by the regulator so reducing the regulators heat but has no effect on the stator output unfortunately.
If y'all pass a gyre through a magnetic field information technology generates juice. The but way to reduce that is to make the field weaker, the coil smaller or reduce the number of times it passes through the field (revs). Hence the 380w kit which has a weaker magnets and smaller windings.

But conspicuously it'due south the stator or aprilia would issue a new regulator or stat

Different from an alternator that won't produce current unless you lot excite information technology and I call back what protects information technology only when a diode fails does it go into meltdown

Mail Options Cheers(0) QuoteReply Posted: 19 Sep 2018 at thirteen:27I believe most alternators use an electromagnet in the armature so when non energised the magnetic field collapses and they produce no output.
The rsv (and most modern bikes) uses permanent magnets so are in consequence outputting at a fixed charge per unit all the time. Makes information technology very simple as there is no live feed etc but much less adaptable to load than an alternator is.

Produced dc though if you put voltage into them they became a motor imagine in those days where loftier revs would be 8k max and now. The poor wee things would explode
Quite fond of the idea of the Magneto though I call back they stick them on some project bikes my bsa had one of y'all took the end off it and stuck it in your pocket it wouldn't get not that bike theft was big then

Many high performance competition engines including aero engines utilise dual magneto's
Might exist more than efficient than what Aprilia utilize in the Gen 2 :-)

what could be easier than a light powerful design similar this. Its twats like nippondenso and piaggio who didnt design the organisation correctly , alongside the canbus sh*tty electrics where whatsoever fault anywhere in the system tin burn out the magneto.

I guess because it's not safety related so the current laws don't force them like as in the swing arm smashing saga
Information technology must be obvious that reputation is everything and why the japs peradventure are where they are now. Our British bikes brutal to bits and pissed oil And we stuck our heads in the sand until it was as well late and we had the best engineers in the world
