Axial flux motors are considered the ultimate future of electric vehicles and most importantly of electric aviation because they have a high torque-to-weight ratio, which is ideal for aircraft. Companies like Rolls Royce and Magnax have intense research and development in progress on these motors. Interestingly, the first-ever electrical generator, developed by the genius Michael Faraday, was an axial flux type. You can see the axis of rotation is parallel to flux lines. However, it never got its day in the sun back then.
