Abstract
A load machine for a combustion engine test bench includes at least one eddy-current brake associated with at least one electric drive. The brake includes a toothed ferromagnetic rotor secured to a shaft mounted so that it can rotate through a casing containing at least one induction coil borne by an internal peripheral region of the casing, so as to generate a magnetic field across which the rotor is intended to pass in order to generate eddy currents which brake the rotation of the shaft. The shaft is coupled to the combustion engine to be tested, and the electric drive is a variable-reluctance electric motor.
