In the automotive field, a common solution utilized for electric vehicles consists in the use of permanent magnet synchronous motors (PMSM), however this is not sustainable due to the presence of rare earths in them. The scarcity of these materials combined with their widespread use in various technological sectors have highlighted the criticality of continuing to use this configuration, shifting the interest of automotive manufacturers towards alternative solutions that avoid the use of rare earth materials. One of these, adopted by car manufacturers such as Renault and BMW, consists in replacing the PMSM with a wound rotor one (EESM or WFSM) whose performance is however inferior.
