Abstract：In this paper, a tubular linear PM (permanent magnet) generator with dual translators and dual Halbach PM arrays is presented for low speed direct-drive wave energy conversion. The operation principle is illustrated to increase the flux density, efficiency, and decrease the detent force. Firstly, based on electromagnetic loading, motion displacement, and average speed, the structure and parameters of the generator are obtained. The electromagnetic characteristics are analyzed and verified using finite element method (FEM) and magnetic field analysis model. Secondly, the structures of Halbach PM arrays are optimized to increase radial magnetic flux density and decrease axial magnetic flux density. In the condition of constant speed and sine speed, the output efficiency is calculated. Finally, a tubular prototype is tested in the condition of different wave parameters. All the results show that compared with other linear generators, the generator with dual translators have the advantages of high flux density, high output efficiency, and low detent force fluctuation.
