Abstract

Several linear synchronous generators for the exploitation of sea wave energy have been proposed. Such machines do not require reactive power for the magnetization since they use permanent magnets for the excitation. The use of permanent magnets in a rough environment such as the marine environment may be a very weak point in the application of these kind of devices. In order to overcome this difficulty, the authors in this paper propose a linear synchronous electrical generator. Its excitation uses ferrites as suitable solutions to extract energy from sea waves. This paper describes the analysis and design of an improved axially magnetized tubular permanent-magnet machine in which several innovative constructive solutions have been carried out to build a low cost, easy to assemble and robust machine. A Ferrite Tubular Linear Permanent Magnet Generator prototype has been made. Several simulation results are shown illustrating the system response to various outputs, including externally applied loads.
