A linear PM generator with triangular-shaped magnet is proposed, which has higher electromagnetic characteristics, superior performance and low weight as compared to conventional linear PM generator with rectangularshaped magnet. The Individual Parameter (IP) optimization technique is employed in order to optimize and achieve optimum performance of linear PM generator. The objective function, optimization variables; magnet angle, Mθ(�)(θ), the pole-width ratio, Pw ratio (�p/�mz), and split ratio between translator and stator, Sa ratio (Rm/Re), and constraints are defined. The efficiency and its main parts; copper and iron loss are computed using time-stepping FEM. The optimal values after optimization are presented which yields highest efficiency. © JES 2016 on-line : journal/esrgroups.org/jes. date: 2016 publisher: Engineering and Scientific Research Groups official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-84994106583&partnerID=40&md5=c761dda009d94081b8fa5bf5fd7cd313 full_text_status: none publication: Journal of Electrical Systems volume: 12 number: 3 pagerange: 583-590 refereed: TRUE issn: 11125209 citation: Hussain, A. and Ibrahim, T. and Nallagoowden, P. and Memon, F.
