The paper presents results of a comparison of two analysis methods of a Line Start Permanent Magnet Synchronous Motor (LSPMSM), which can be applied to optimization of its construction. Such important procedure properties, as computation time and the possibility of employing it in an automated process of searching for the optimal design were of particular interest. A supposition, that the time required for accurate FEM calculations and further processing of computation data can be a substantial constraint in a multi-parameter, multi-criterial optimization process, has been investigated. In the paper an attempt is made: a) to estimate how inaccuracy in prototype construction and uncertainty of material properties influence machine performances and b) what is a credibility of experimental verification of optimization computations. Such quantities as properties of permanent magnet and electromagnetic sheet, as well as a tolerance of some motor dimensions, have been taken in the analysis into account. The analysis results concern a few important machine properties: electromagnetic torque, stator current and rated efficiency. A selected machine optimization task is employed in the analysis.
