Re: e-Buggy: Alternator Conversion

@dajsinjo: congratulation, seems the 200A controller works flawlessly, perhaps we should list down all the controller that has been proved to be working. Do you have any problem in starting it up ?, what is the lowest rotor supply for a reliable start up ? I am still waiting for 200A controller thi...

That noise from your video is sooo familiar. I think you need a washer behind the fan to keep it from hitting the case?
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

Re: e-Buggy: Alternator Conversion

The bottom tap/connection looks like it is not the same distance as the others maybe that is a center connection of the windings ? (star-configuration) Please measure the resistance between each connection and let us know ... Maybe if you scratch the plastic/glue/isolation stuff away from the elect...

Re: e-Buggy: Alternator Conversion

Dajsinjo , that's an interesting alternator that you have there , those connections coming out of the stator are absolute PERFECT and make it very easy to connect cables to !!

Re: e-Buggy: Alternator Conversion

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?

Re: e-Buggy: Alternator Conversion

Conversion finished! Controller should be flying in soon Sweet :D Whats the weight? What kind of controller are you using? At what voltage? Zenon 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 controlle...

Re: e-Buggy: Alternator Conversion

I understand everything about powering it up, I have read alot online. Everything except the 3 wires from the spools. What do I do with them? Do i just cut them off and connect to the brushlessESC? Is it that simple? Or do I re-arrange them somehow? I know you mentioned Delta/star-pattern, I just c...

Re: e-Buggy: Alternator Conversion

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 converting my ...
