Motor
I suggest new design of stator of Axial Electric Engine.
Stator consists from series of coils W1, W2, W3 laying on different diameters d1, d2, d3.
Which provides different torque and rotating spead.
By changing continuesly the power relation betwen W-is, we get Continuesly Variable Transmission with maximal gear ratio d3/d1.
To increase this ratio we can do W1 radial.
