Abstract: This paper describes the design of a direct-drive permanent-magnet generator for use in a novel sea-wave electrical generator. The basic system is briefly described and the target specification derived from the device and the wave tank performance. The design for the brushless permanent-magnet generators is then developed using SPEED PC-BDC and verified using Finite Element Analysis (PC-FEA). A diode bridge model is also tested using Portunus system simulation.

Keywords: permanent magnet generators; brushless generators; renewable energy; wave energy; wave power; electrical generators; finite element analysis; FEA; simulation; diode bridge models; speed range; pulsating power delivery.
