1. Increase the field current. The field current is what creates the magnetic field in the alternator, and increasing the field current will increase the strength of the magnetic field. This will in turn increase the voltage generated by the alternator.
2. Increase the number of turns in the stator windings. The stator windings are the coils of wire that are wrapped around the stator core. Increasing the number of turns in the stator windings will increase the voltage generated by the alternator.
3. Use a higher voltage regulator setting. The voltage regulator is what controls the output voltage of the alternator. Increasing the voltage regulator setting will tell the alternator to generate a higher voltage.
It is important to note that increasing the alternator rated voltage will also increase the current output of the alternator. This may require upgrading the alternator's wiring and other components to handle the higher current.
