Optimization Design of Linear Induction Motor and Study of the 3-Phase Asymmetry Phenomenon

This paper carried out the optimization design and performance analysis of linear induction motor (LIM) which is used for spherical induction motor. Firstly, based on the principle of equivalent circuit and MATLAB software, an optimized LIM design program combining magnetic circuit and circuit was proposed, obtaining more accurate magnetic field distribution data of LIM. Then, the dimensional parameters are optimized based on ANSYS and Maxwell finite element analysis (FEA) software. Finally, the research and optimization scheme of LIM three-phase asymmetry phenomenon are carried out.
