Just a late night idea for a metalworking & electrical project in need of a reality check. I've always been fascinated by the old open-frame style salient pole synchronous motors and AC generators. I wouldn't mind building a working model of one at some point, probably to be coupled with a suitable 2-4 cylinder inline engine or air compressor as the case may be.
See Here, here or here for visual examples.
My question is how feasible this sort of project really is from a hobbyist perspective. Obviously the stator is going to require a laminated core with the correct number of slots for three phase windings. Short of having a stack custom made, maybe an old cieling fan motor or alternator core might suffice? As for the rotor, would laminations be strictly neccesary? Does the alternating field extend into the pole shoes at all or are they purely DC? Damper windings might require a bit of thought.
Are there any good resources to look into as far as the winding calculations? Particularly for figuring how many turns of what gauge for the DC field windings.
