Designing a Permanent Magnet Linear Generator Multi Air-gap structure using the Finite Element Method

This paper deals with the design of a Permanent Magnet Linear Generator Multi Air-gap Structure (MALG) using the Finite Element Method (FEM). The cogging force, which occurs due to the interaction between stator teeth and the Permanent Magnet (PM), is reduced by the MALG dimensions. The generated voltage is analyzed for both no-load on the multi-air gap flux density. This paper predicts the thrust force and flux linkage.
