Patent ID: 10103615

Abstract:
Eddy current retarder equipment (1) able to be carried on board a vehicle, includes: a stator assembly (2), including inductor windings (23) forming a circuit (4), a rotor assembly (3) designed to be mounted on a transmission shaft of the vehicle, including an armature (31) facing the inductor windings (23), control elements (6) for establishing a linear setpoint (β), excitation elements (7) for exciting the inductor circuit (4) from an electric power source (5) of the vehicle as a function of the setpoint (β), a speed sensor (9) for supplying information relating to the rotational speed (Ω) of the rotor assembly (3), a sensor (10) of the strength of current supplied to the inductor circuit (4), processing elements (8) for estimating, at a given moment (t), the retarding torque supplied by the equipment (1).
