Abstract

According to the characteristics of the linear generator for direct drive wave energy converters, a novel primary permanent magnet transverse flux linear generator (TFLG) is studied. The structure has the advantages of simple structure, easy maintenance, and high mechanical strength, which is especially suitable for the harsh marine climate environment. Firstly, the operating principle of the generator is described, and the three-dimensional equivalent model of the generator is established by magnetic circuit method. The mathematical expressions of back electromotive force (EMF) and cogging force are derived. Secondly, the EMF, waveform distortion rate and cogging force are taken as optimization objectives, the key structural parameters of the generator are selected as the influence factors. The local multi-objective optimization of the primary permanent magnet TFLG is carried out by the Taguchi method, and a group of parameters with suitable comprehensive performance are obtained. Finally, the effectiveness of the method is verified by three-dimensional finite element simulation.
