Abstract
Dispositif de mesure comprenant une génératrice délivrant une tension alternative sinusoïdale de fréquence proportionnelle à la vitesse de rotation de son rotor, et un multiplicateur de fréquence comportant : un rotor lié en rotation au rotor de la génératrice et pourvu de dents rotoriques ; un stator comprenant une première et une deuxième paire de plots dentés, les dents rotoriques présentant avec les dents statoriques de la première paire de plots un couplage magnétique opposé à celui desdites dents rotoriques avec les dents statoriques de la deuxième paire de plots ; un premier circuit électrique comprenant un bobinage d’excitation entourant dans un sens l’un des premiers plots et dans l’autre sens l’un des deuxièmes plots ; et un deuxième circuit électrique comprenant un bobinage de mesure entourant dans un même sens les premier et deuxième plots entourés par le bobinage d’excitation, les extrémités du premier circuit électrique étant reliées à la génératrice. FIGURE DE L’ABREGE : Fig.3Measuring device comprising a generator delivering a sinusoidal alternating voltage of frequency proportional to the speed of rotation of its rotor, and a frequency multiplier comprising: a rotor linked in rotation to the rotor of the generator and provided with rotor teeth; a stator comprising a first and a second pair of toothed studs, the rotor teeth having with the stator teeth of the first pair of studs a magnetic coupling opposite to that of said rotor teeth with the stator teeth of the second pair of studs; a first electrical circuit comprising an excitation winding surrounding one of the first pads in one direction and one of the second pads in the other direction; and a second electric circuit comprising a measurement winding surrounding in the same direction the first and second pads surrounded by the excitation winding, the ends of the first electric circuit being connected to the generator.
