To avoid further thread jacking I decided to open an own thread about my "generator from scrap parts" project.
I did a lot of online research about AC generation and got at least some results...
According to what I remember from school I need a synchronous generator if I want to run anything but purely resistive loads.
Since the frequency depends on the rotation I need a fairly precise speed control on the motor.
To control the voltage I need a regulator for the excitation. I know a guy who built his own mechanic regulator so I might be able to get some help on that.
Is anyone here familiar with the workings of old small generator sets (1-2kVA range)? Those things already existed 50 years ago and I don't think they were built extremely complex since they were supposed to work in harsh environments.
