Perkins 4-108 fitted with a Generator

I have an Endeavour 37 with a perkins 4-108 and have heard of fitting a gererator , such as an auragen, directly to the engine. Has anyone done this...what are your opinions of it. Thanks for your input.

I'm not sure what you mean by "directly to the engine". Do you mean to install it between the drive coupler and the shaft?

No Mycroft, not there...from what I understood the auragen was set up simular to the alternator. Thanks.

This isn't a new concept, nor is it unusual. There are several companies making something with various similarities out there. The biggest problem with installation becomes side loading of the crank.

That and running the engine at an exact RPM to keep the frequency correct

Re: Perkins 4-108 fitted with a Generator

There's a reason why the automotive industry switched from generators to alternators over half a century ago. And the boat industry followed suit.


But if you understand the difference between an alternator and a generator, or you simply dislike having machines that begin with an "A", by all means, go for it.

That's the beauty of these typs of systems. They're like modular honda inverter generators....ie. no specific speed required for frequency, only for maximum power.

Re: Perkins 4-108 fitted with a Generator

Seems like the OP misspoke. Auragen calls their device a "power generator" or more precisely an "axial flux induction power machine" and it is by no means anything like a "generator" of any conventional type. It appears to be a pancake shaped alternator [sic] that can be bolted up to other machinery.


But calling it a generator...You might as well say you're buying a power station. That's just the wrong thing to call it.

He was just using a generic term. I wonder if he may not be better off with a stand alone "axial flux induction power machine" a no. are made but are called generators I think.
