In the first video i will be modifying the rotor of the car alternator using permanent magnets which means i am not going to give any power supply to the rotor winding and remove the brushes so that it can become a permanent magnet generator. In the second video i am going to convert a 12v car alternator to 24v so that i can reach 12v at lower RPM than rated. The third video is a simple experiment to find out the minimum RPM at which the car alternator produces 12v DC.
