Re: [FWDLK] GENERATOR QUESTION

[Mike & Sharon Higgins <clearcreek@xxxxxxxxxxxxxxxx>]

The generator will produce Voltage.  The Voltage is limited, or controlled, by the specific set of connecting points in the Generator Regulator.  The generator only produces Amperage if it is connected to a circuit that will allow the voltage to push a current (amperage) through.  The amperage is not controlled by the generator, by the Current limiter portion of the Generator Regulator.  The difference in the Armatures is not in how much amperage is produced (each will produce as much as needed in the system) but by the capability of the wiring in the armature.  If the wiring is heavy enough, the current produced will flow without too much interference (resistance) and will not produce too much heat.  If the armature wiring is not low enough in resistance, the generator will heat up too quickly, and "burn up."  The result, then, if you use a higher capacity armature, is that the generator will be capable of handling the higher demands of your electrical system without overheating.  The rest of the wiring in the system would have to be capable of handling that extra 5 amps, though, or you may experience melting insulation on the wires.

 

There is something called "Inductive reactance" which is much more affective to an Alternator system, and has little effect in an older generator system, and has to do with the limit of amperage produced by a charging system.  Bur the short answer is that if you install a higher capacity generator armature into you 30 amp system, and if you electrical system demands that 35 amps, your regulator must be set to allow the 35 amps to flow, and your wiring must be capable of handling the additional current without overheating.

 

Good Luck.

Hello Members

 

Concerning our vintage generators........................

 

If 2 armatures physically interchange--is there any problem switching a 30 amp armature for a 35 amp one????

 

I always wondered exactly what makes the additional amps??
