Quantitative Assessment of Magnet Thickness Impact on PMSM Motor Performance for EVs

The primary objective of this project is to optimise the magnetic thickness of the permanent magnet employed in an electric three-wheeler’s Permanent Magnet Synchronous Motor (PMSM). In particular, the goal is to investigate how modifying the thickness of Curved shape Neodymium Ferrite Boron (NdFeB) magnets affects key performance parameters, including torque, efficiency, losses, and flux. The optimization process involves analytical calculations to compare the existing PMSM design with the optimised design. Finite Element Analysis (FEA) simulations are conducted to accurately determine the magnetic flux distribution within the motor and evaluate the desired performance parameters. The results of the analysis will be presented using graphs, charts, and tables, allowing for easy comparison between the two designs. The study’s findings will help identify the optimal magnet thickness for the PMSM rotor, which can provide maximum torque output, increased efficiency, reduced losses, and improved flux distribution. The outcomes of this project have significant relevance to the electric three-wheeler industry. They can offer valuable insights into designing PMSMs that deliver superior performance with improved efficiency and reduced energy consumption. Additionally, the optimised rotor design can help extend the range of electric three-wheelers, making them more practical and appealing to consumers.
