Abstract

The aim of this paper is to presents a study and derived expressions of the magnetic flux density in the air-gap of the linear synchronous permanent magnet generator, utilized in the wave energy converter. The significance of a well-modelled magnetic flux density-term is important, when, for example, modelling the induced voltage and dimension the support structure due to the magnetic force between the stator and translator at no load situation.
