Abstract
(EN) Provided are an electric motor protection method and apparatus based on temperature measurement and calculation, and an electronic device and a medium. The method comprises: acquiring a vibration file, wherein the vibration file is a voltage signal that is adapted to a vibration event of an electric motor voice coil; calculating a predicted temperature of the electric motor voice coil according to the vibration file; and when the predicted temperature is higher than a pre-set temperature threshold value, performing correction processing on the vibration file.
(FR) La présente invention concerne un procédé et un appareil de protection de moteur électrique basés sur une mesure et un calcul de température, un dispositif électronique et un support. Le procédé comprend les étapes consistant à : acquérir un fichier de vibration, le fichier de vibration étant un signal de tension qui est adapté à un événement de vibration d'une bobine acoustique de moteur électrique ; calculer une température prédite de la bobine acoustique de moteur électrique en fonction du fichier de vibration ; et lorsque la température prédite est supérieure à une valeur seuil de température prédéfinie, effectuer un traitement de correction sur le fichier de vibration.
