Abstract
(EN)
Provided are an electric motor state monitoring apparatus and an electric motor state monitoring method. The electric motor state monitoring apparatus (10) is used for monitoring the state of an electric motor (100). The electric motor state monitoring apparatus (10) comprises a receiver (11) and a signal processing unit (12). The receiver (11) and the electric motor (100) are placed separately for receiving in a non-contact manner the tested signals radiated by the electric motor (100). The signal processing unit (12) is connected to the receiver (11) for determining the state of the electric motor (100) according to the tested signals to generate the state signal representing the state of the electric motor (100).

L'invention concerne un appareil de surveillance d'état de moteur électrique et un procédé de surveillance d'état de moteur électrique. L'appareil de surveillance d'état de moteur électrique (10) est utilisé pour surveiller l'état d'un moteur électrique (100). L'appareil de surveillance d'état de moteur électrique (10) comprend un récepteur (11) et une unité de traitement de signal (12). Le récepteur (11) et le moteur électrique (100) sont placés séparément pour recevoir sans contact les signaux testés rayonnés par le moteur électrique (100). L'unité de traitement de signal (12) est connectée au récepteur (11) pour déterminer l'état du moteur électrique (100) en fonction des signaux testés pour générer le signal d'état représentant l'état du moteur électrique (100).
