Zusammenfassung:The paper analyzes permanent magnet geometry effects on cogging force of permanent magnet linear generators. The dynamic modeling of the generator's performance is based on sensitivity analysis technique and finite-element representation. The generator is coupled to a particular mechanical system for sea wave energy extraction applications. The proposed methodology involves minimization of cogging force through parametric sensitivity analysis on alternative magnet profile configurations.
