It's my understanding of alternator operation that the voltage is "built-in" by the number of poles, the number of turns on the rotor/stator, and least of all by the regulator. The speed controls current, not voltage. No, this is not correct. The open circuit voltage is given by the rate of change in magnetic field the stator sees. This means that it varies with the RPM. ....and, it varies with the field current. Terry k |
