Design of a Linear Generator for Wave Energy Conversion in Peninsular Malaysia

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.
