A Scholarly Review of Methods for Design Optimization of IPM Synchronous Motors Used in Electric Vehicles

Unlike the conventionally fueled vehicles used in the transportation system, electric vehicles emit zero carbon content or any hazardous discharge as they are highly environmentally friendly. Therefore, an optimized electric motor design for excellent performance has become a requirement for electric vehicle drive system developments in the automotive industry.. This paper includes a scholarly review of previously adapted optimization algorithms and a case study of optimizing the permanent magnet synchronous motor with a V-type buried magnet (IPMSM) design from the rotor side. This gave optimal placement of the magnets and geometric positions. Using the optimizing algorithms, smaller magnet sizes and other optimized parameters have been achieved, effectively ensuring higher performance requirements and efficient use in electric vehicle applications. The results are validated through the FEA analysis and optimization done by the OptiSLang software.
