Handel, P H; Handel, P

This patent describes a motor vehicle including an internal combustion engine, four wheels mounted for rotation to the vehicle, each of the wheels having an axle, a first pair of the wheels being operatively connected to the internal combustion engine so as to be driven thereby, a pair of bearings mounted on the axle, a support tube mounted for rotation to the bearings, the improvement comprising means for providing an electric drive for the non-internal combustion engine driven pair of the wheels. The electric drive means consists of a homopolar axial field motor including a stator and a rotor, the stator forming a brake shoe and the rotor forming one of a brake drum and disc for respective ones of the non-internal combustion engine driven wheel pair, a permanent magnet of high energy density material mounted to the support tube and rotatable therewith, at least one iron disc mounted on the support tube in close proximity to the permanent magnet. The stator includes an enclosure, a plurality of support elements mounted to the enclosure and extending radially inwardly therefrom, and a plurality of coils mounted on the support elements in spaced relationship to one another, a plurality of pole rings mounted on the permanent magnet, the pole rings including radially extending support arms, and a plurality of axially magnetized pole pieces, the pole pieces being constructed of high energy density material, respective ones of the pole pieces being positioned between respective pairs of the coil.
