Yes, it can be done.Clad wrote:Can we create the excitement of an unmodified auto alternator by means of a small DC 12V motor attached to the same pulley as the alternator?
In fact, it is a bit like the principle of the rotating diode alternator in which the excitation is produced by the equivalent of a DC motor built into the alternator.
In practice, the excitement will increase gradually with speed, and not suddenly when speed is reached, but maybe that is quite a good thing?Clad wrote:Thus it would be excited only when the wind turbine reaches a sufficient speed to produce the 12V of the DC motor ...
