Abstract[German]
Für einen EC-Motor (1) wird die Lage seines Rotors durch Injizieren eines Spannungssignals (320) und Auswertung der resultierenden Stromschwankungen in den Phasen (21, 22, 23) des EC-Motors ermittelt. Das Injizieren wird für jede Phase (21, 22, 23) jeweils dann ausgesetzt, wenn die Spannung in der Phase (21, 22, 23) einem Maximalwert (550) nahe ist.[English]
For an EC motor (1), the position of the rotor thereof is determined by injecting a voltage signal (320) and evaluating the resulting current fluctuations in the phases (21, 22, 23) of the EC motor. The injection is suspended for each phase (21, 22, 23) respectively when the voltage in the phase (21, 22, 23) is close to a maximum value (550).[French]
Pour un moteur EC (1), la position du rotor de celui-ci est déterminée par injection d'un signal de tension (320) et par évaluation des fluctuations de courant résultantes dans les phases (21, 22, 23) du moteur EC. L'injection est suspendue pour chaque phase (21, 22, 23) respectivement lorsque la tension dans la phase (21, 22, 23) est proche d'une valeur maximale (550).
