many more years of service.The choice of voltage regulator is equally important as the quality of the overhaul. Dynamos need BOTH voltage and current control, without these features it’s easily possible to drive the dynamo to the point it burns out the field winding and/or the armature.
The output voltage of the generator is regulated by comparing the output voltage with a reference and controlling the voltage regulator in order to control the main exciter field. The generator must be designed to maintain the nominal output voltage for the full electrical load throughout the opera...
