A double-sided linear flux-switching permanent magnet machine applied in marine rudder direct drive applications is presented. The starting performances of the machine are calculated by finite element method. The simulation results of the proposed DLFSPM are verified by the experiment. The results have verified that the machine is suitability marine rudder direct drive applications.

Abstract The aim of this paper is to explore the possibility of using linear tubular flux switching permanent magnet machines in a free piston energy conversion (FPEC) system. In FPEC systems, acceleration and therefore speed are often relatively high, which impose to have a reduced number of poles, meanwhile the cogging force will be relatively high. In order to reduce the cogging force two techniques are combined. The analysis is done using finite element method.
