Abstract
This paper covers the design methodologies and optimisation techniques studied in the performance improvement of line-start permanent magnet synchronous motors (LSPMSM). LSPMSM performance improvement using design techniques are chiefly limited to either the transient or the steady-state performance improvement, and a focus on only the transient performance improvement may degrade the steady-state performance of the LSPMSM and vice versa. Optimisation studies of LSPMSMs can be categorized in terms of optimisation aim in three classifications: transient performance improvement, steady-state performance improvement, and simultaneous improvement of both transient and the steady-state performance. This study indicates the impact of various variables on the LSPMSM performance improvement. The optimisation review shows that starting cage optimisation without considering the steady-state characteristics as constraints results in synchronous performance degradation. The steady-state performance optimization with transient characteristics as constraints results in a minor synchronous performance improvement though there is the lowest transient performance sacrifice. Multi-objective optimization including a transient and a steady-state characteristic as individual objectives resulted in a more optimum LSPMSM with overall performance improvement. Finally, suggestions for optimisation implementation of LSPMSMs are presented for future research work.Keywords
