Performance analysis of linear switched reluctance generator for different teeth shapes. The generation quality factor

This work presents the evaluation of different teeth shape geometries of a tubular linear switched reluctance generator in order to maximize the machine capabilities for power generation at low speeds in direct drive wave energy converters. For a 1.5 KW 3 phase generator, different geometries will be proposed and evaluated with the scope to achieve greater electromotive force for low speeds despite the adopted control strategy. The optimization study is support by a 2D FEM analysis through which different geometric parameters will be evaluated to maximize the inductance change with the relative displacement between the stationary and mover parts of the machine.
