Abstract
Die Erfindung betrifft ein Verfahren zur Messung eines durch einen Motor (1) fließenden Stromes (IMOT), wobei ein den Motor (1) mit elektrischer Energie versorgendes Leistungsschaltteil (2) mittels einer Steuereinheit (4) über ein Pulsweitenmodulations-Signal (10) gesteuert wird, wobei das Pulsweitenmodulations-Signal (10) einen Schaltzyklus (15) aufweist, und wobei der Motorstrom (IMOT) in einer Zuleitung (8, 8a) zum Leistungsschaltteil (2) oder in einer Zuleitung (9, 9a) zum Motor (1) bestimmt wird. Indem pro Schaltzyklus (15) genau ein den Motorstrom (IMOT) repräsentierender Messwert abgetastet wird, wird ein Verfahren zur Messung des Motorstromes (IMOT) angegeben, welches kostengünstiger und schneller den Motorstrom (IMOT) ermittelt als es beim Stand der Technik der Fall ist. Das Verfahren findet Anwendung in der Motorsteuerung für Gleichstrommotoren.
