Abstract:In this paper, an investigation into different magnetisation topologies for a Long Stator Tubular Permanent Magnet Linear Generator (LS-PMLG) is performed through a comparison based on the cogging force disturbance, the power output and the cost of the raw materials of the machines. The results obtained from the FEA simulation are compared with an existing linear generator described in [1]. To ensure accurate results, the generator developed in [1] is built with 3D CAD and simulated using Finite Element Method… Show more

“…Number of concepts for direct drive WEC has been presented [4][5][6][7][8][9][10][11][12][13][14][15]. Caused by the relatively low vertical speeds of the marine waves and the desire for high output power, the generators share large sizes and hence, high magnetic forces such as cogging forces.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
