Electric vehicles (EV) gained an increasing popularity over the years, especially in the last decade, with significant growth of the sales by 46\% to 69\%. There are multiple reasons for that: the regulations on C02 emissions pushed the automotive industry to focus more on them than the traditional ICE vehicles since they are the only ones capable of respecting the latest restrictions. Furthermore, they are suitable to reach higher performance, but also to adapt to new technologies. Consequently, all the components of the electric traction line are required to have high efficiency. Among them, a lot of research have been focusing on the electric motor and on how taking full advantage from its features.
