Numerical Simulation and Experimental Analysis for a Linear Trigonal Double-Face Permanent Magnet Generator Used in Direct Driven Wave Energy Conversion

Abstract

A schema of slack-moored wave-energy converter using linear permanence magnet is developed. For suitable use in this device, a structure of coreless linear permanence magnet generator is designed. The advantage of this model is the absence of steel core in coils that mean no cogging force is induced. A numerical simulation for analyzing structure characters of generator has been developed. For verification the numerical simulation results, a laboratory scale of generator has been manufactured and investigated. The results from experiments are compared to the simulation and a good agreement is obtained. The study results have also been used for analyzing different designing options to buoy-type direct-driven wave energy conversion.
