Abstract:
The present disclosure relates generally to rotors for electric motor assemblies and methods of making the same, and more specifically, to variable thickness rotors for axial flux motors. More specifically, annular-shaped rotors having interiorly disposed magnets for axial flux motors are provided in certain aspects. The variable thickness rotors may each include an annular-shaped body having a first thickness at a first radial position and a second thickness at a second radial position. The first radial position may be spaced apart from the second radial position. The first thickness may be greater than or equal to about 200% of the second thickness.
