Another thing I would like to point out in case it hasn’t become painfully obvious to everyone. When you see a smaller generator that is advertised as having a “brushless generator head” That pretty much means without exception that it uses capacitor excitation. You have to have brushes and slip rigs on the armature to feed the current to the exciter coil from the AVR for the AVR to function.
In the roster list of features, where it list if it has an AVR or not, it will say “no”, or “not required”, or “brushless”.
Sometimes it will list “capacitor” as the regulation system. But that is a misnomer, because the capacitor is the exciting system, not the regulation system.
I have seen a few make that mistake on this forum by referring to it as a capacitor regulated system. The capacitor is the exciting system, it needs no regulating system because the voltage regulation is inherent in the design and construction of the generator head.
Large industrial/military generators and three phase generators use an excitation generator mounted on the same shaft as the primary generator, but you won’t see it on residential grade systems.
Generator manufactures/brands that I can think of that have generators with brushless (capacitor excited) heads on some of their generators, or use brushless heads on all their generators.
Baldor
Coleman
Subaru/robin
Yamaha
Yanmar
north star (northern tool)
Dewalt
MMD equipment
Devlbiss
Winco
Makita
Pramac
Porter cable
And many more……
One that is absent from the list is Honda. Honda has a obsession with using AVRs on their equipment. And since Honda is considered top dog, any thing they do must be better than the rest, so generator manufactures that try to act “high end” use AVRs because Honda does. That is why high end Chinese generators (Honda clones) brag about having an AVR because Honda uses them. It is strictly a thing of “follow the leader” Other manufactures that are not trying to “follow the leader” offer brushless units, because they have found out that they give less problems over the generator service life.
Note: Many generator manufacturers mate Honda engines to brushless heads, but Honda it’s self, only uses AVR type heads as far as I know.
