alternator for generator!!

[Ren]

Good luck in your attempts avr. May I suggest making the switch as frictionless and hardy as possible. As I'm sure you're aware mechanical switching is prone to wear over time resulting in failure. I built my first pulse motor with a mechanical microswitch. It worked great and gave me some insights into what was happening in my rotor. However, after a few thousand cycles the switch would fail, especially at higher speeds.

Have you considered a form of commutation? I am a little unsure as to what the purpose of your switch is when I read your posts...?

i know alternator is the worst to use to make electricity but it is a challange that i need undestand y not!
i know that in order for the alter. to create elec. it needs the rotor exited, so in return it is wasting energy, i totaly understand. but i need to try!

I wonder if you shuld be thinking of a permanent magnet generator:
