Abstract

Selon l'invention, une inductance de fuite et la somme d'une résistance primaire et d'une résistance secondaire peuvent être mesurées avec une précision élevée uniquement par les valeurs d'amplitude de tension et de courant sans utiliser la différence de phase entre la tension et le courant. Un dispositif de commande de moteur à induction comprend une unité de calcul d'instruction de tension (14) pour appliquer individuellement des tensions sinusoïdales de deux fréquences différentes préétablies, de telle sorte qu'un flux magnétique alternatif est généré tandis qu'un moteur est stoppé, une unité de calcul d'impédance (16) pour obtenir deux valeurs d'impédance à l'aide de valeurs d'amplitude de tension et de valeurs d'amplitude de courant aux fréquences respectives, et une unité de calcul de constante (17) pour obtenir une première valeur d'inductance de fuite à l'aide de la différence entre les deux fréquences et de la différence entre les deux valeurs d'impédance, obtenir une seconde valeur d'inductance de fuite à l'aide de la valeur d'impédance obtenue par l'une des deux fréquences, et mesurer/calculer une valeur d'inductance de fuite à l'aide des première et seconde valeurs d'inductance de fuite.
