Title (EN) SPECTRAL SPREAD FOR ELECTRIC MOTOR
(FR) ÉTALEMENT SPECTRAL POUR MOTEUR ÉLECTRIQUE
Abstract:
(EN) The invention relates particularly to a method for controlling an electric motor, comprising generating, by means of an electronic control circuit, an electrical signal for controlling the electric motor. The aim of the signal generated is to reduce the electromagnetic parasites in AM radio bands as well as in the band [0 k Hz; 125 k Hz] (used particularly by RFID chips associated with certain sensors), without generating acoustic parasites in the audible frequency bands.
(FR) La description se rapporte notamment à un procédé de commande d'un moteur électrique, comprenant une génération, par un circuit électronique de commande, d'un signal électrique de commande du moteur électrique. Le signal généré vise à réduire les parasites électromagnétiques dans les bandes radio AM ainsi que dans la bande [0 k Hz; 125 k Hz] (utilisée notamment par des puces RFID associées à certains capteurs) et ceci sans générer de parasites acoustiques dans les bandes de fréquences audibles.
