ABSTRACT:
A variable reluctance electrical generator is disclosed having a unique structure which, for any given design parameters, tends to maximize air gap areas and thus minimize mmf drops thereacross. The mean magnetic flux paths all generally include a constant reluctance parasitic air gap and a variable reluctance active air gap. The portion of the magnetic circuit defining the active air gap is adapted to magnetically saturate before the portion of the magnetic circuit defining the parasitic air gap areas thus eliminating the parasitic air gap as a design limitation. In the exemplary embodiment the parasitic air gap is located radially outwardly of the active air gap areas such that the parasitic gap reluctance is much less than the minimum active gap reluctance. The design of the alternator is also such as to simplify its assembly during fabrication and to thereafter permit ready disassembly of its major components from one another for repair or other purposes.
