Great idea and it saves space of course. The only small downside is that cars do not like unsprung mass. They want as much weight as possible on the springs.
High unsprung weight leads to a hard ride, and excessive tyre damage when you hit a bump, but possibly fixable to a certain degree by using airsprings.
I can understand driving each wheel with its own motor eliminating transmissions and diffs and potentially simulating tractions control and ABS. However surely they would be best placed centrally in the car to improve CG and also keep the unsprung weight to a minimum.
@Aldoor In a traditional car the unspung weight comes mostly from engine and transmission that is no langer needed in this concept so the CG is is now on the lowest point of the car.
Mark Nieuwenhuizen unsprung weight is the weight of wheels and tyres not engine and body. The issue with high unsprung weight is that when you hit a bump, higher inertia causes a harder bump, consequently a hard ride.
Great presentation. But kind of glossed over the mechanical advantage of the axial flux motor, and of course totally skipped his solution that he came to south of Munich.
Currently using this methodology in hybrid projects. However, I'll disagree on the part about needing "excellent quality" to meet automotive solutions. Actually, intrinsically, such quality levels are easy to reach by emotors.
Hi, I'm for new innovations but engines in the wheel will come in rust dirt and especially in those parts of the country where it is snowing, raining and other countries that do not have asphalt roads. hope the inovators have thought about these possibilities
@Lopez: Rust and dirt can be kept out with good design. On the other hand you are right that this design will not be for everyone. That is the big change with hub motors. For the car it will be the end of the way Henry Ford thought about fabrication. With a hub motor you can built de coach anyway you want and just ‘add the motors’. In the near future cars will nog Ben mass produced anymore but build to fit with less moving parts prone to failure.
Consider a Magnetic Levitrain that rides on tracks by a magnetic field. I wonder if you can take a section of the track of a Magnetic Train and bend it into a Circle to make the outer part of a wheel. The car would be attached to the inner part of the wheel which would be levitated away from the outside of the circular spinning part by a magnetic field. there would be no physical contact between two surfaces and not even any need for bearings. It would be a totally frictionless between the inside and the outside of the wheel, driven by a magnetic field. Also consider that if the Electromagnetic motors are on each wheel, the wheels could attached to the vehicle by their own vertical shaft. There would be no need for a physical linkage bar and no rear axial. The wheels could be perfectly aligned in forward and backward or in sideways motion. Wow. Perfect sideways parallel parking.

Actually, he’s correct because the tolerances required are now +/- 0.01mm. That’s “excellent quality”.
