Let's see if I can ask this mechanical question with an engineering twist.
I am needing to convert an alternator from 12v to 24v. I was able to source a 24v stator and voltage regulators from other models but the rotor is only available in 12v.
So my question is, what exactly is it that controls the max current output, say 140 amps for the 12v model and 70a for the 24v?
I work with generators and the high and low voltage conversion is done in the stator windings only, no changes to the rotor. But, these units will continue increasing output with load until failure (without circuit breaker protection). What makes an automotive alternator different from the typical generator?
Is the rotor configured so that the stator magnetism counters the field to limit max current output? Could I put a resistor in series with the 12v rotor field windings to reduce the maximum current output?
