Design, optimisation, analysis and experimental verification of a new line-start permanent magnet synchronous shaded-pole motor

In this study, an optimal design of a new line-start permanent magnet synchronous shaded-pole motor (LSPMSSPM) is proposed. A genetic algorithm optimisation method based on transient two-dimensional finite-element method (FEM) is applied to reach a global optimum design. Advantages and challenges of the proposed LSPMSSPM are investigated, and its performance characteristics are calculated. Efficiency, power factor, starting behaviour and cost as important key factors are analysed. Finally, FEM results are verified with experimental tests.
