Abstract
Eddy current brake equipment includes a stator assembly and a rotor assembly adapted to be mounted on a transmission shaft of a vehicle. One of those assemblies includes inductor windings and the other assembly includes an armature facing the inductor windings. The inductor windings are selectively excited from an electricity source of the vehicle in response to a power feed setting. A processor is provided to estimate the braking torque that the equipment can provide as a function of the speed of rotation of the rotor assembly, of the temperature armature, and of the temperature of the inductor windings, and of at least one value for the power feed setting.
