Sounds like you are exciting the field of the alternator off its own output. Probably one of the old crummy Motorola-style alternators that had the extra diode-trio.I have a car alternator and I'm turning it with a motor from a cordless drill. using a seperate power suorce to get it started. ounce removed I can keep it running. but try to add another load it crashes...
It's not the fuel that keeps it going,it's not even in my car, it's on my bench.Oh, I see. YOu have multiple devices being powered from the alternator and you want to be able to turn them on and off freely without having to restart the alternator because for some reason it shuts down when the load gets too low.
50W...that's kind of a huge resistor just to burn off power, or you'd need circuitry to monitor the output current of the alternator (everything except the resistor) and switch the resistor in whenever that current gets too low.
Any idea why the alternator shuts off when the load gets too low? Why would it stop? It's fuel powered...it's the fuel that keeps it spinning not the load.
Yeah. Well then, of course it's going to turn off. You got no more energy entering in the system, and nothing is 100% efficient. So every time the energy cycles through the system you lose a bit.Sounds like you're trying to build an overunity generator.
you know, you shouldn't be so negitive. I'm just trying to learn something newDon't they teach conservation of energy in high school science class anymore? Why do people still build these kinds of devices?
