Abstract:
An eddy current brake device for bringing a vehicle to rest, the device comprising:a stator mounted to a frame of the vehicle; a plurality of poles disposed along a perimeter of the stator; a pole plate member disposed at an end of each of the plurality of poles, wherein the pole plate member has a plurality of grooves disposed in a top surface of the pole plate member; a plurality of coils, wherein each of the plurality of coils are wound about each of the plurality of poles, wherein an adjacent pair of poles and coils form an electromagnet when each of the plurality of coils are energized; and a rotor in communication with a transmission axle of the vehicle and located concentric with the stator, and wherein a relative rotation of the rotor with respect to the stator produces eddy currents between the plurality of poles of the stator and an outer surface of the rotor, causing the rotor to stop rotating relative to the stator.
