Abstract
An axial flux motor includes a housing; a drive shaft disposed within the housing; at least one rotor; and at least one stator. The at least one rotor includes a diametrically-magnetized single pole pair magnetic ring having a rotor aperture defined through the center of the magnetic ring, where the drive shaft extends through the rotor aperture and where the at least one rotor is fixed to the drive shaft. The at least one stator includes a number of conductive windings and a stator aperture, where the drive shaft extends through the stator aperture and where the drive shaft is rotatable within the aperture. The at least one stator is configured to generate an axial magnetic field that causes the at least one rotor to rotate, thereby rotating the drive shaft.
