Up to now, most electrified cars have synchronous machines with permanent magnets in the rotor (so-called PSMs, permanent magnet synchronous motors). They are efficient and were generally regarded as easier to manufacture than externally excited machines, which use coils in the rotor to generate the magnetic field. Vitesco Technologies has overcome some substantial obstacles to designing externally excited machines: By harnessing many years of experience from series applications and through targeted design changes, it became possible to achieve the same performance class with both technologies (PSM and EESM) – and to use the existing space in the platform design for both options. By applying a sophisticated winding principle, the innovative EESM rotor becomes an economically attractive option within the most recent drive platform. Especially, when high-performance requirements necessitate a big magnet mass in a PSM, EESM machines will be more affordable and more sustainable.
