Patent

CA 2371493

The invention relates to a method for operating an electric motor (32) to which a microprocessor or microcontroller (23) and a non-volatile memory (74) are assigned, whereby, during the occurrence of a fault, at least one operation data value of the motor is automatically stored in the non-volatile memory (74) in a program-controlled manner. The invention also relates to an electric motor for carrying out such a method. The invention serves to increase the operational reliability of a motor since the stored data can be queried occasionally or after the occurrence of a fault. In addition, the invention demonstrates how such faults are processed.

L'invention concerne un procédé permettant d'actionner un moteur électrique (32) auquel sont adjoints un microprocesseur ou un microcontrôleur (23) et une mémoire non volatile (74). Lorsqu'une erreur se produit, au moins une valeur de données de fonctionnement du moteur est mémorisée automatiquement dans la mémoire non volatile (74) de manière commandée par programme. L'invention concerne également un moteur électrique approprié pour mettre ledit procédé en oeuvre. L'invention permet d'augmenter la fiabilité de fonctionnement d'un moteur, du fait que les données mémorisées sont consultées de temps en temps ou après l'apparition d'une erreur. L'invention indique également la manière de résoudre ce type d'erreurs.
