This paper deals with the design of a single-phase line-start permanent magnet synchronous machine. The parametric optimization is used for achieving improved parameters of the single-phase line-start permanent magnet synchronous machine compared to commonly used induction machines. The optimization includes a time-consuming transient analysis considering the machine?s starting process and its synchronizing capabilities. One selected optimized design is analysed in detail and the results are discussed. The main contribution is a developed procedure for the optimization of the single-phase line-start permanent magnet synchronous machine of small power with class efficiency in IE2. Moreover, the manufacturability and the final material
consumption are considered during the optimization.
