[Oeva-list] Anyone have experience with permanent magnet alternators?

Hi Tim,
I'm not really educated in this area, but your question made me do some
research.

You might find this interesting; I'm not sure if there is more.

Interesting idea for a series hybrid car.
I think the reason a lot of people use a permanent magnet for wind is
because at low wind speeds the PM alternator is most efficient. I'm
wondering if there are some people over at ARE in Newberg that could help
here.

However if you are using a diesel engine wouldn't the RPM be constant at
the sweet spot and therefore you wouldn't need the low end efficiency of a
PM?
A series hybrid; isn't that what a diesel electric train is all about?
I wonder what they use?
