Title (EN) ACTIVE ELECTROMAGNETIC DAMPING SYSTEM FOR SPINDLE MOTORS
(FR) SYSTEME ACTIF D'AMORTISSEMENT ELECTROMAGNETIQUE POUR MOTEURS A BROCHE
Abstract: front page image
(EN)A method of damping resonances in a rotating system is disclosed, which includes developing a representation of vibrating movement in the rotating system, taking the derivative of that representation and applying an out-of-phase active damping force based on the derivative to the rotating system to damp out the movement.
(FR)Technique d'amortissement des résonances dans un système rotatif. On crée une représentation d'un mouvement vibratoire dans le système rotatif, on calcule la dérivée de cette représentation et l'on applique une force d'amortissement active déphasée dépendant de la dérivée du système rotatif pour amortir le mouvement.
