Abstract
Purpose – A double-sided tubular linear machine layout is presented for direct-drive applications, with particular focus on wave-energy conversion. The paper documents both the computational and mathematical analysis of this novel machine layout. Design/methodology/approach – The selection and finite-element optimisation of the permanent-magnet array is presented. The machine is then modelled using magnetic circuit theory. By simultaneously solving the system of equations, a demonstrative design is developed and simulated so as to validate the mathematical model and compare the performance of the new layout with a traditional layout.
