ASA’s Electric Motor at the Heart of Mercedes-Benz’s Vision One-Eleven

Mercedes-Benz is showcasing the future of electric performance motors in the new Mercedes-Benz Vision One-Eleven concept car, unveiled at the International Design Centre in Carlsbad, California.  Paying homage to a 70s icon, the C111, the concept Mercedes-Benz Vision One-Eleven features YASA’s unique axial-flux electric motors, a powder metallurgy soft magnetic composite (SMC) opportunity, is paving the way for a new era of innovative design engineering and high-performance electric driving experiences.

The unique topology of the YASA electric motor frees up space and opens exciting new design parameters, as evidenced by the stunning Vision One-Eleven. In contrast to common radial motors, seen in the majority of electric vehicles today, YASA’s revolutionary axial-flux motor requires just one third of the space, is one third of the weight, and delivers double the torque density.

A radial flux motor can also only be driven hard so many times because as the copper windings get hot electromagnetic resistance increases, reducing available power. However, moving from radial designs to YASA’s axial flux design brings direct oil cooling of the copper, keeping it cool which means endlessly repeatable acceleration and access to peak power for the driver, providing an unparalleled performance driving experience. As well as saving weight by using 60-80% less iron and significantly less copper than conventional e-motors.
