The eVal project aims to provide a critical technology building block to enable the development of components and sub-systems for the more/all electric aircraft. The main aim of the project is to develop and validate a tool that is able to evaluate and assess the health status of electric motor drives, such as shown in the figure below.

The proposed tool is ‘non-invasive’, in that it is only ‘fed’ with the values of readily-available and/or easily-measurable parameters (such as voltage and temperature at for example the electrical machine’s terminals). Through advanced modelling techniques, these variables are ‘translated’ into health-status identifiers, capable of informing the end-user of the health status of the important aspects of the drive.

The project is currently in its closing stages with significant achievements having been achieved. The proposed tool has been shown to be highly feasible and accurate in its predictions. The project has already resulted in two peer-reviewed IEEE publications.

Project eVal marks a significant stride forward for the Department of Electrical Engineering in its quest to become a world player in the field of electrification of transport.
