Axial flux motor design been around since 1800s not new invention,

Cooling and durability is the biggest challenge

Yasa took over by mercy

Anonymous, 20 hours agoFrankly, most of us would be happy with 200hp and an an even smaller, lighter and cheaper moto... moreYeah, If this motor is less efficient, then lower weight is useless and the achievable range will be worse than with the other heavier motor.

If It's so revolutionary, why only Mercedes is planning a car with It and only one so far?

Tesla motors weight between 70 lbs (32 kg) to 110 lbs (50kg) for comparison.

The difference in weight is pretty small If we compare the total weight of the car, basically one extra passenger.
Because of this I expect minimal improvement in range, so what author wrote about needing lighter battery packs for the same range is unrealistic.

And most of all, efficiency is more important than a few kg shaved off. What you might save in motor weight, you'll pay 3-4 times over in battery if you lose efficiency.
