Structural Principles and Electromagnetic Design for Permanent Magnet Starters with Auxiliary Poles

The structure and principles of permanent magnet starters with auxiliary poles were described,and its performance characteristics were analyzed.Accurate electromagnetic analysis of the starter was conducted with finite element software Ansoft Maxwell 2D,and new products were designed using the simulation results.Test results verify the correctness of FEM,which lays a theoretical foundation for the future development of new products.
