als je zo artikels lees, krijg je regelmatig claims over energieefficientie en powerdensity
hier is bvb een motor die nogal over de lippen gaat de laatste tijd
YASA...
axial flux EV motors for the next generation of all-electric AMG performance models, quickly became a meeting of minds, built on a shared commitment to engineering excellence, innovation, and the shaping of performance EV’s for the fast-developing electric age.

ik vraag mij a
f is dat nu een van de beste motoren beschikbaar ? 42KW/kg en waarom is die powerdichtheid in principe belangrijk ? je zou denken dat de efficientie het belangrijkste is ?
In real-world test trials, Yasa’s prototype motor delivered 550kW of power from a 13.1kg package, equating to 42kW/kg, almost double the previous industry benchmark.
en Mercedes dweept met yasa

tot je ook bemerkt dat motoren
'in wheel motoren' aan het worden zijn bij de auto's, blijkbaar hier een design met kunsstof stator... daarom is idd voor een inwheel motor de powerdensiteit per kg een belangrijke factor. En blijkbaar iedereen komt tot dezelfde conclusie dat de axial flux motor de beste oplossing is
Orbis Electric has introduced HaloDrive, an advanced axial flux motor-generator designed

The axial flux motor-generator has been designed for commercial transportation, trucking fleets, stationary industrial power generation and passenger vehicles, as well as marine systems and aerospace platforms. The technology acts as an alternative to electric motors such as permanent magnet synchronous motors (PMSM).
HaloDrive has been piloted by leading passenger vehicle OEMs for in-wheel propulsion systems and in heavy-duty trucking fleets as diesel replacement generators. In these commercial applications, the electric motor has reportedly delivered significant cost savings, and in one case, has been improved fleet fuel efficiency by 61%.
Installed on the driveshaft or an axle, the HaloDrive motor converts the truck’s braking energy into cost-saving electricity to power mobile refrigeration without plugging into the grid. Orbis Electric’s HaloDrive has been engineered to fit within a wheel, reducing vehicle weight and improving range by 20%. The system can be installed in three hours.
