Abstract

This paper presents impacts of different permanent magnet materials and operational temperatures on the performance of interior permanent magnet (IPM) machines for electric vehicle applications. Variations of the average torque, torque ripple, cogging torque, and no-load EMF with different neodymium-iron-boron (NdFeB) permanent magnet materials and operational temperatures are investigated. Based on finite-element method (FEM), performance about the ripple and cogging torques of the IPM machine will be analyzed and some useful conclusions can be provided for researchers and engineers in the related traction motor industries.
