RE: Homemade Alternator
I think it is a little bit too large in diameter for a truck.? I'll try to find a link.

RE: Homemade Alternator
I was planing in using a 1.5 - 3 volts hobby motor conected by belt throughout the flywheel
my main concern is that the AMPS might not be enough to charge the 4 cell 6 volts rx battery.

RE: Homemade Alternator
An alternator is actually pretty easy to build.... although time consuming to do a good job and make it look professional. The important thing is to regulate both the speed of the alternator and the voltage output. You will also need to use a rectifier to convert AC to DC. The basics of an alternator is nothing more than and iron core, wire coils and magnets... and equal # of magnets and wire coils. The easiest thing for you to do would be to find an appropriate sized brushless motor and use it for an alternator...
Do an internet search for building an alternator or how to build an alternator..... I am sure you will find some good info. Also, here is a link to a GREAT magnet source.......... http://www.wondermagnet.com/main.shtml

Years ago, Maynard Hill used the generator for bicycle lights for keeping the batteries on endurance planes charged. I don't remember exactly when, but Model Aviation published an article on the plane that told what setup he used. It was probably in the early 80s. Might be useful information.

RE: Homemade Alternator
Here is an example of what I had in mind:
RB Innovations Turbo charger
But instead of the fan a 3 Volts DC motor or a servo motor with a 6 or 7 volts
regulator.

RE: Homemade Alternator
you will still need more then a regulator, since the output of a DC motor is AC... still think a sullivan might fit your needs fairly well, it isn't as large as it looks.

RE: Homemade Alternator
[sm=sleeping.gif] NO, I tested, I also thought the same thing too but its output is DC
I hooked up a servo motor in to the flywheel of the engine and it gives
aproximately between 15 volts at idle and 28-30 at almost full, and all is DC
but the amps, I don't think is high.
