Abstract

Variable speed by eddy current, the rate applicable to an engine, comprising an outer casing (1) motionless, whose bottom penetrates shaft (2); cilíndrico a first vessel (3), sympathized the shaft for your fund; a second glass cilíndrico (4) internal, coaxial of the first vessel, sympathized dl output shaft (5) drive for your fund and fitted with a block central (6) substantially cylindrical and multipolar on its periphery, around which is determined one hollow cylindrical annular (7); and a cover (8) external, having a body hollow support (9), substantially cylindrical, adapted to be introduced mostly in the cited hollow cylindrical annular said second inner vessel, being crossed cover by said output shaft variador, which can rotate on bearings (10) fixed axial hole made at the top, being the case, the two vessels and top mentioned consisting of a magnetizable material high permeability and being arranged, around the end of cited body shaft support closer to the bottom of the second vessel, winding a first coil (11) electric that to receive the passage of electric current producing a magnetic field intensity depending on such electric current causing said magnetic field eddy current ones in the first vessel with the movement on the second glass in front of the inside of the first vessel driven by the shaft, hac iendo move said eddy current second vessel and therefore, the tree drive, characterized in that at the opposite end to the first coil, the hollow body holder is provided with an annular (12) coaxial, essentially flat, whose outer surface is dispuestamuy near the inner face of the second vaso being wound on said piece a second annular coil (15) electrical, which is a device brake being practicadasen at least one of the two facing surfaces of the annular coaxial or the inside of the second vessel, a plurality of notches (13) between each two consecutive of which is determined a portion (14) as tooth, all so, to receive said second coil passing the electric current while passing the stops running for the first electric coil, establishing a magnetic field intensity depending on such electric current incurred currents fou cault by relative movement of teeth with respect to nicks and the facing surface, which create itself a magnetic flux which opposes the rotation of said second vessel and therefore the drive shaft.
