Mercedes-Benz offered a brand new sports activities automotive research, the Imaginative and prescient One-Eleven. Its technical highlights embrace the extraordinarily highly effective and extremely environment friendly axial-flux motor developed by electrical motor specialist YASA. The British firm has been a 100% subsidiary of Mercedes-Benz AG since July 2021. (Earlier put up.)

The Mercedes-Benz Imaginative and prescient One-Eleven is impressed by the custom of the C 111 experimental autos from the Nineteen Sixties and 70s, which have been used to check Wankel and turbodiesel engines. They have been additionally prototypes for testing polymer-based bodyshells. The extraordinarily (aero)dynamic mid-engine sports activities automobiles are thought of design icons of their period, not least as a result of their distinctive gullwing doorways and crowd pleasing orange-and-black paintwork.
Know-how highlights embrace a brand new battery idea that includes high-performance liquid-cooled cylindrical cells with a novel cell chemistry. As soon as extra, the intensive information of the motorsport consultants from Mercedes-AMG Excessive Efficiency Powertrain in Brixworth discovered its manner into this promising idea for future performance-oriented batteries.

Other than that, the Imaginative and prescient One-Eleven options two exceptionally highly effective and superior axial-flux motors from YASA. Mercedes-Benz is growing this know-how along with YASA to massive scale manufacturing maturity for its next-generation electrical drives.
Axial-flux motors are considerably lighter and extra compact, but extra highly effective than comparable radial-flux motors at the moment utilized in 99 % of all electrical automobiles. In an axial-flux motor, the electromagnetic circulate runs parallel to the motor’s rotational axis, which is extremely environment friendly. In a radial-flux motor, the circulate runs perpendicular to the rotational axis. In comparison with radial-flux motors, they’ve significantly larger and extra enduring energy reserves, which delivers an entire new degree of efficiency.

Alongside its energy and torque density, one other main profit is the slender bundle, which reduces each its weight and dimensions. The burden of an axial-flux motor is only one third of that of present electrical motors with the identical energy output. On the identical time, it requires simply one-third of the house occupied by a radial-flux motor. This opens up utterly new choices for engineers in addition to new freedoms within the design of an electrical automobile as demonstrated by the Imaginative and prescient One-Eleven.
The longer term technology of YASA axial-flux motors will likely be produced on the Mercedes-Benz Berlin-Marienfelde plant. The motors manufactured there will likely be on the coronary heart of the forthcoming powertrain for the efficiency phase.
