This paper presents the design modeling and analysis of linear permanent magnet generator for wave energy conversion using finite element method. The time-stepping finite element technique is used to determine electromagnetic characteristics and analyze the efficiency. The main parts such as; copper loss is analyzed on the different variation of winding input excitation and the core loss is determined based on various specific loss curves data in order to analyze its effect on frequency. The influence of main dimension of stator is analyzed on electromagnetic characteristic and copper loss.

This paper presents the design of linear permanent magnet generator for wave energy conversion using finite element analysis software. Four designs have been proposed which are simple, lightweight, portable and can produce 100 Watt electric power. Air-cored linear permanent magnet generator have been chosen and their electromagnetic characteristic were analyzed using finite element analysis. The determined electromagnetic analysis reveals that rectangular permanent magnet arrangement (Rect-PM) design gives efficient performance as compared to other designs.

Abstract The aim of this paper is to explore the possibility of using linear tubular flux switching permanent magnet machines in a free piston energy conversion (FPEC) system. In FPEC systems, acceleration and therefore speed are often relatively high, which impose to have a reduced number of poles, meanwhile the cogging force will be relatively high. In order to reduce the cogging force two techniques are combined. The analysis is done using finite element method.

Malaysia is a small country surrounded by numerous oceans that can provide sufficient renewable energy for utilization. This work is to propose a design and modeling of a portable linear permanent magnet generator for the Wave Energy Conversion system that suits with the local wave parameters. Linear generator is preferable as compared to the rotary generator due to the direct drive technology that promises low maintenance cost. Three linear permanent magnet generator designs with different types of permanent magnet layout have been proposed as the permanent magnet used can provide better flux density compared to other topologies. Preliminary results for the air gap flux distribution and open-circuit flux distribution are demonstrated and discussed are shown to be as expected.
