Abstract
Linear permanent magnet generators are a potentially useful technology for wave power applications. Typically, optimisation and comparison of these generators is based on an electromagnetic analysis with limited regard for the structural analysis. This paper presents a comparison of two alternative designs of the double-sided linear permanent magnet synchronous machine which includes structural and bearing requirements for a more accurate assessment of cost and feasibility. It is shown that both cost and feasibility depend heavily on these issues due to the large internal and external forces acting on the machine.
