That is for the nominal voltage of Li-ion 3.7V but it is higher than nominal when fully charged. What I heard is that you shouldn't runn them over 30V it worked with two lead acid in series on video

yes but it is so rusty ! It will take a lot of efort to unscrew it

I think delta gives higher rpm and less torque, power is the same

I am still waiting for 200A controller this one was 80A version of the same ( Mystery pentium 80 ) brought by my friend Zoltan There was a lot of trouble with 12V, it was bearly working, and it worked bether with less power at armature. on video stator is powered with 24V and there was no...

here it is http://www.youtube.com/watch?v=Qhr0bPiFxsE

YES YES YES !!!! you are RIGHT!!! the one at 10 o'clock is a star connection ! I took the rubber off and saw 6 wires connected to it, others have 2 wires. resistance is half between star and phase than between phases. I am still waiting for the controller , than you will see them spinning!

that is exactly what friend of mine suggested! I have allready masured the resistance and it is the same in ALL combinations! It doesnt say but it lookes like Bosh alternator, and yes, it is very easy to connect cabels.

My brother crashed his Honda Prelude, so I got my hands on his alternator :twisted: and took it apart I am a bit confused about 4 wires comming out from stator, the bridge lookes like it has 8 diodes. Is it possible that it is 4-phase alternator?

I don't know abou the weight, maybe 3 kg for the rotor(armature) I use rheostat 0-10 Ohm + 4.5 Ohm armature resistance For stator I orderd this controller...

Conversion finished! Controller should be flying in soon

Yes, just cut the wires and connect to brushless(and sensorless) esc. Other 3 ends are solderd together somewhere in the spool, which is a star, don't touch that, you don't need to rearrange it ! You don't need diodes any more, unless you want to arrange some strange regenerative braking where...

rotor lookes realy nice

This will be a motor soon !

Thank you widodo for very usefull information! I will order that cheap controller for now and see how it works. Dajs

What would happen if you would power rotor with 12V ? I think those alternators are very robust, they work near hot engine at some 14V + some drop at diodes, so I guess when they work as motors , in normal enviroment, they can work at higher voltage and stil not burn out. Anyway I am...
