I need to verify some of my theories using a car alternator, and I also have some experiments in mind... So with holiday sales time of year, I picked up an alternator with 126 amps maximum under load for about $40...
The first thing I did was remove the voltage regulator and separated the DC output from the input of the brushes..
Now I can power the rotor from a DC supply (or battery) and direct the output to a separate load..
The first test I want to do is a simple rotor / current check.. Power the rotor with 12V , connect a load to the output, and spin it up.. I am expecting to see minor fluctuations in current draw going to the rotor coil, but there should be no direct link between input current and Output current.. This should help me understand how rotating magnetic fields behave in relation to Mutual Induction.
I also have another idea or two to try, I had AI's do a deep search and found no info on my proposed idea, so I remain hopeful..
We will see.. First to get this all mounted up and find a suitable motor to spin it
