Effect of Manufacturing Tolerances on Electric Motor Performance Figures

Manufacturing tolerances and material properties variations can affect the performance of an electric machine, with possible consistent differences between the expected outputs and the experimental measures.
A correct understanding of this phenomena and a good knowledge on how to mitigate it, can improve the electric motor design procedures by increasing the attention on some details and selecting proper geometries or materials, with reduced sensitivity to parameters variation. In addition, the same technique can be also adopted to local optimizations of an existing design, improving the motor performance.
During the thesis, the candidate will study the state of the art in the field of the Design of Experiments (DoE), Robust Design and sensitivity analysis methodology (like Montecarlo Method), and implement the analysis process in the open-source framework SyR-e (https://sourceforge.net/projects/syr-e/), developed and maintained from some of PEIC members.
Since the topic is wide, the cooperation with other students is possible.
