Abstract
Systems and methods are provided for a drive mechanism of a vehicle, that may include: a rotor comprising a ring of a plurality of magnets located about a circumference of a rim of a wheel of the vehicle, the plurality of magnets generating a first magnetic field; a stator comprising a plurality of coils, the stator mounted to a body of the vehicle, and located outside a wheel of the vehicle and proximate to an outer edge of the ring of the plurality of magnets; and wherein the plurality of coils of the stator, when energized by an AC waveform, generate a second magnetic field stator, and further wherein an interaction between the first and second magnetic fields creates an attractive force causing tractive motion of the wheel about an axis of rotation of the wheel.
