About the Stator

[Lansonus]

If I wanted to place magnets on the stator of an induction alternator, what material would be best? should I

 use a non-magnetic material like wood? or do I want it to be magnetic? and if so, steel?

[Chagrin]

If you're asking what material is best for the stator, that would be steel. Remember that not only is the flux coming out of the "front" of the magnet (the side facing outward from the stator) it also comes out the back. You want to make a good path for that flux to it's neighbors -- basically you want a full flux "loop".

I don't have anything to add.  I just wanted to give you some positive reinforcement for your much improved posting style.

I think he meant best for the rotor

agree with mt man- lasonus, much better to ask simple questions, and get simple answers.

terminology issues, not to nit-pick, but to help you get across your point:

1. you dont place the magnets on the stator. the magnets go on the rotor, the rotor rotates, and the stator stays static, and has coils on it. (though with
   
2. induction alternator is a weird thing to say. around here, you might hear about an induction motor conversion, but with permanent mags, i guess you would not talk about induction.
   
   

now- your question.

yes. you want some sort of high permeability (sp?) material behind the mags. you are trying to make a 'circuit' that lets the flux flow from one pole of the mag, and back into the other pole. along the way, you would like to have some sort of gap with one side of a coil of wire in it. iron/steel, etc will control and tighten the path that flux takes, such that you can get more bang for your magnet buck.

iron on the stator with the coils is a whole different ball of wax.
