Design and Modelling of a Portable Pico Linear Generator for Wave Energy Conversion System

Abstract

This paper will focus on designing and modelling the portable pico linear generator for the wave energy converter application. The aim for this research is to develop a permanent magnet linear generator which has the weight less than 20 kg and can produce up to 80 W. A thorough literature review has been done on type of configurations, stator structure, magnetization and type of cored to select the best features of the linear generator. Three proposed designs of the permanent magnet linear generator is presented and each of the proposed design performance is simulated using the Ansys Maxwell software. Comparison on the preliminary result such as the air gap flux distribution, back-emf, flux linkage and thrust force of the three proposed designs will be shown and discussed.
