Abstract

© 2016 Institution of Engineering and Technology. All rights reserved. The latest demands for electrical machine are that they must be compact and light and have torque density required to tolerate environmental and load conditions. Reduce the usage of permanent magnets has also become the main focus in designing a new electrical machines, especially for electrical vehicle applications. Research has been conducted on four different sizes of machines, from the original size to progressively smaller ones: machines A, B, C and D. At the beginning of machine design, the assessment of the electromagnetic performance of the machines and magnetization analysis have been conducted using Infolytica Magnet software. Then, Infolytica ThermNet is applied to perform thermal static or transient analysis, either as standalone or coupled to static or time-harmonic since temperature is a major factor threatening the magnetism of magnets, and the life and stability of machines. Finally, two prototype machines are developed and tested in order to validate the simulation results.
