Pericolo di bruciare lo statore [thread n°3]

The series regulator assists with cooling the stator by interupting, and thus reducing, current flow from the stator.

That action has nothing to do with the question of whether adding additional loads with the OEM shunt regulator reduces stator heating - it does not.

In the shunt system the voltage is dragged down by drawing current. Whether the current draw is by the shunt regulator or other electrical loads makes no difference. The stator sees the total current draw and it is that total current draw that contributes to stator heating.

Non saprei..., fino ad ora si è sempre sostenuto che lo statore produce una determinata quota di energia in base al numero di giri, indipendentemente dalle richieste. L'eccesso, con regolazione tipo shunt, verrebbe dissipato dallo statore come calore.
Il regolatore tipo serie invece riuscirebbe a cortocircuitare lo statore facendogli produrre solo l'energia necessaria a soddisfare le richieste.
Detto ciò, risulta evidente che avendo un regolatore tipo shunt, avendo assorbimenti vari, ci sia meno eccesso di energia da smaltire sotto forma di calore.

There is much confusion on this subject on the internet.

It is the voltage output of the stator that rises with increasing RPM, not the energy produced. The POTENTIAL power output of the stator does rise with higher RPM but the ACTUAL power output is a function of the load and what current it draws.

If nothing is connected to the stator then no current is drawn and there are no losses in its windings thus no heat produced.

When a load is connected to the stator current flows through it. The higher the current the greater the losses in the stator windings and it heats up.

In a shunt type regulator current is drawn both by the regulator and the bike's electrics. The more current drawn the lower the voltage produced. For any given RPM a certain amount of current must be drawn to reduce the output to the desired voltage. If more current is drawn by the bike's electrics less is drawn by the shunt regulator.

That is why adding accessories has no impact on stator heating or stator life.

Quindi aumentare le utenze, ovvero tenere accese luci od altro è del tutto inutile per evitare una eccessiva temperatura allo statore?
Quindi ha senso o no sostituire un regolatore "shunt" come l'FH020 con uno "serie" come l'SH847AA?
Hai mai letto questo https://belinassu.it/396108567/396108572/, cosa ne pensi?
Dopo tanto parlare sarebbe bello avere delle certezze sul tema.

These are two separate situations. Increasing the consumption of power by accessories has no impact on stator heating when using a SHUNT type regulator because the voltage regulation is a function of total current draw.

Converting to a SERIES regulator results in an overall decrease in total current draw thus resulting in less stator heating.

I have converted both of our bikes to series type regulators. I know the subject well. I have seen all of Belinassu's material.

Quindi ritieni che sia bene passare da un regolatore shunt a un regolatore serie.
Hai per caso provato un Webenergy?
