Latest Patents
One of Hardy's latest patents is a method of making a variable reluctance A.C. electrical generator. This invention features a unique structure that maximizes air gap areas, thereby minimizing magnetomotive force (mmf) drops across the generator. The design includes a mean magnetic flux path that consists of a constant reluctance parasitic air gap and a variable reluctance active air gap. The active air gap is engineered to magnetically saturate before the parasitic air gap, effectively eliminating it as a design limitation. Additionally, the exemplary embodiment positions the parasitic air gap radially outward of the active air gap areas, ensuring that the reluctance of the parasitic gap is significantly less than that of the minimum active gap. This innovative design not only enhances performance but also simplifies assembly and disassembly for maintenance purposes.
