Title
(DE) VERFAHREN ZUR ELEKTRONISCHEN KOMMUTIERUNG IN GLEICHSTROM-ELEKTROMOTOREN

Abstract
(DE)
Bei einem Verfahren zur elektronischen Kommutierung in Gleichstrom-Elektromotoren, die durch Pulsweitenmodulation der Bestromung gesteuert werden, welche periodisch mit positiven und negativen Stromwerten und zwischenliegenden Bestromungspausen erfolgt, wird die Gegeninduktionsspannung gemessen, wobei der Nulldurchgang der Gegeninduktionsspannung über den Schnittpunkt der Einhüllenden an die Gegeninduktionsspannung mit der Nulllinie bestimmt wird. Die Pulsweitenmodulation der Bestromung wird verändert, wenn der Nulldurchgang von positiven oder negativen Stromwerten der Bestromung überdeckt wird.
(EN)
In an electronic commutation method in direct current electric motors which are controlled by pulse width modulation of the energization which takes place periodically with positive and negative current values and intermediate energization pauses, the counter‑induction voltage is measured, wherein the zero crossing of the counter‑induction voltage is determined by means of the point of intersection of the envelope to the counter‑induction voltage with the zero line. The pulse width modulation of the energization is changed if the zero crossing is covered by positive or negative current values of the energization.
(FR)
L'invention concerne un procédé de commutation électronique dans des moteurs électriques à courant continu commandés par modulation d'impulsions en largeur de l'alimentation électrique, réalisée périodiquement avec des valeurs de courant positives et négatives et des pauses d'alimentation électrique intermittentes. Selon l'invention, la tension d'induction mutuelle est mesurée, le passage à zéro de la tension d'induction mutuelle étant déterminé au moyen du point d'intersection des enveloppes à la tension d'induction mutuelle et de la ligne du zéro. La modulation d'impulsions en largeur de l'alimentation électrique est modifiée lorsque le passage à zéro des valeurs de courant positives ou négatives de l'alimentation électrique est couvert.
