An eddy current braking apparatus is disclosed. The apparatus includes a stator, a coil of wire, and a drum. The stator has a plurality of poles and is mountable to a frame of a vehicle. The coil of wire is wound about each of the plurality of poles and wherein adjacent coils are electrically connected to form an electromagnet. The drum is adapted to receive a wheel and tire assembly and wherein the drum is rotatably mounted to a vehicle axle, and wherein an eddy current is developed between the drum and the stator, from the relative motion of the drum with respect to the stator, thereby retarding rotation of the drum and wheel and tire assembly.

1. An eddy current braking apparatus, comprising: a stator having a plurality of poles, wherein the stator is mountable to a frame of a vehicle; a coil of wire wound about each of the plurality of poles, wherein adjacent coils are electrically connected to form an electromagnet; and a drum receiving a wheel and tire assembly wherein the drum is rotatably mounted to a vehicle axle, a frictional brake fixed to the vehicle frame and adapted for frictional contact with the drum, thereby preventing rotation of the drum; and wherein an eddy current is developed between the drum and the stator, from the relative motion of the drum with respect to the stator, thereby retarding rotation of the drum and wheel and tire assembly. 2. The apparatus of claim 1, further comprising an end cap fixedly secured to each of the plurality of poles. 3. The apparatus of claim 1, wherein the coil of wire is comprised of flat wire. 4. The apparatus of claim 1, wherein the stator further comprises a stator mounting plate fixed to a vehicle frame and configured for mounting the stator thereon. 5. The apparatus of claim 1, wherein the stator is made of 1005 steel. 6. The apparatus of claim 1, wherein the drum is made of 1005 steel. 7. The apparatus of claim 1, wherein electromagnets are created in a north and a south pole of adjacent poles. 8. The apparatus of claim 1, wherein a changing magnetic flux field is created between the stator poles and a surface of the drum when the coil is electrically energized. 9. The apparatus of claim 1, wherein the frictional brake is fixedly secured to the stator. 10. An eddy current brake apparatus, comprising: a stator having a plurality of poles, wherein the stator is mountable to a frame of a vehicle; a coil of wire wound about each of the plurality of poles, wherein adjacent coils are electrically connected to form an electromagnet; a drum receiving a wheel and tire assembly wherein the drum is rotatably mounted to a vehicle axle; and a frictional brake in selectively frictional contact with the drum for selective inhibiting rotation thereof, and wherein an eddy current is developed between the drum and the stator, from the relative motion of the drum with respect to the stator, thereby retarding rotation of the drum and wheel and tire assembly. 11. The apparatus of claim 10, further comprising an end cap fixedly secured to each of the plurality of poles. 12. The apparatus of claim 10, wherein the coil of wire is comprised of flat wire. 13. The apparatus of claim 10, wherein the stator further comprises a stator mounting plate fixed to a vehicle frame and configured for mounting the stator thereon. 14. The apparatus of claim 10, wherein the stator is made of 1005 steel. 15. The apparatus of claim 10, wherein the drum is made of 1005 steel. 16. The apparatus of claim 10, wherein electromagnets are created in a north and a south pole of adjacent poles. 17. The apparatus of claim 10, wherein the stator is made of 1005 steel.
