I performed my internship in the laboratory G2Elab, based in Grenoble. It is a research laboratory specialized on electrical engineering and its application. The main objective of this internship was to analyse the Tesla Model S motor, characterize in its frequency response, valid the 2D model created before and finally obtain the parameter of the equivalent electric circuit considering the harmonic impact. Then, all of this information will be useful to create a scientific paper to exhibit in a conference.
