Abstract: front page image
(EN)The invention relates to a method for reducing torque ripple in a motor controlled by a torque regulator. According to the invention, a correction signal dependent on the angle between the stator and the rotor is summed with the input of the torque regulator. The apparatus of the invention comprises a signal processor capable of generating a correction signal reducing the torque ripple, which correction signal can be summed with the output of the torque regulator and which can be generated in the signal processor on the basis of angle data regarding the angle between the stator and the rotor.
(FR)L'invention concerne un procédé de réduction des ondulations de couple dans un moteur commandé par un régulateur de couple. Selon l'invention, un signal de correction tributaire de l'angle que forment le stator et le rotor est ajouté à l'entrée du régulateur de couple. L'appareil comprend un processeur de signal susceptible de générer un signal de correction permettant de réduire l'ondulation de couple, signal qui peut venir s'ajouter à la sortie du régulateur de couple et qui peut être généré dans le processeur de signal selon les données d'angle concernant l'angle que forment le stator et le rotor.
