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.

Abstract: This laminated rotor for an eddy-current braking device includes a stack (1) of flat elements (2) parallel to each other, made of ferromagnetic material, the said stack being bounded in the direction perpendicular to the said flat elements (2) by two opposite surfaces (5), as well as at least one housing through the thickness of the said stack for accommodating a ferromagnetic component (8) made of ferromagnetic material which is solid or laminated in another direction than the said stack (1), able to establish a magnetic bridge extending between the said two opposite surfaces (5) and/or to hold the said flat elements assembled.
