these things are normal for electric motors, including e-bike motors.95% efficiency and max torque at zero rpm???
Looking at torque/efficiency curves seems the Mahle has a much wider range of higher efficiency than all other cheaper motors.
Think they are trying to match rare metal type motors at significantly lower price...??
Theirs is not an exception.
Where they claim first is the idea of wireless transmission of electric power. Think of your mobile phone charging pad or your electric toothbrush charger. Wireless chargers work in the same way as electrical transformers, it's invented 150 years ago, in the late 19th century.
