Flux Switching Linear Generator: Design, Analysis, and Optimization

Flux switching linear generator and Vernier hybrid machine comprise of solid translator with huge weight. As there are slots and teeth at both ends of the translator it should be thick enough because of its design limitation. Therefore, while generating power from the sea wave, it results in poor dynamics because of its bulk weight. In this chapter, a new design of the FSLG is presented along with the model where the translator weight is reduced and magnetic flux linkage of the main stator is improved by applying static steel core in the secondary stator. The produced voltage, current, power, efficiency, core loss, force ripples, and cogging force reduction for the FLSG is presented. The new translator is lightweight and can generate enough electrical energy from the oceanic wave as shown in the dynamic model. Genetic algorithm is used to find out the optimal design of the translator and stator before it is finally selected. To observe the improvement and possibility to utilize this design of FSLG, finite element analysis is conducted by utilizing ANSYS/Ansoft.
