Free Electricity generator alternator

[chatelot16]

due to the wire diameter of the winding!

space in an alternator is limited: the main 220V winding takes up all the space ... the 12V winding is only an accessory

but that does not change anything: even if the main winding was 12V it could only transform the mechanical power which drives it into electric power, with a loss in passing

Thank you for your answers
the 12v is limited to 100 watt for what reason ??
DIODE OR OTHER ???
Thank you

Welcome!


This is due to the fact that the winding of the gene only provides only 100 watts!

It's pipo because when trying to recharge the battery by this process it will drain the battery even faster because of the loss in the engine / alternator process.

ok thanks for your explanation
then an alternator example 12v 50A
how fast it has to rotate to give this power out?
By cons it seems to me that an alternator must be excited to produce, so how to modify this so that it works as a simple generator?
THANK YOU FOR YOUR ANSWERS

[chatelot16]

there are different kinds of alternator

those with an excitation coil in the rotor are easy to understand

that of the 2-stroke generator in this video is a self-regulating

there is a condenser and a winding which looks like a starting winding of single-phase motor ... the rotor has nested 2winding and 2 diodes: it produces the excitation current without carbon, using the condenser

it's a bizarre system that I can't explain in detail

It depends on the model and the design ...

Hello
Here is finally an autonomous generator which seems true, I suppose because it is on sale, I have the video and the explanatory text to make it but in English need help especially the alternator, the number of wire is strange and know the rotation speed to choose the dc motor
awaiting your response thank you in advance

But why this forum Does this kind of imbecility attract you like flies?
