Da es sehr temperaturstabile Shunts gibt, lässt sich mit einer derartigen Einrichtung relativ temperaturunabhängig der Strom messen. Ein Nachteil ist jedoch der hohe Kostenaufwand für den Shunt.electronic driven DC motors are used in particular as a drive from radiator fans in Used motor vehicles. Controllers for this purpose are, inter alia, binding and / or shorts determine the DC motors and suitable for such cases precautions to meet. It is known, for. B. the stiffness of an electric motor determine by measuring the motor current. For this Current measurement is usually a shunt inserted. Since there are very temperature stable shunts, let yourself with such a device relatively independent of the temperature Measure current. A disadvantage, however, is the high cost of the shunt.
Es ist daher eine Aufgabe der vorliegenden Erfindung, ein kostengünstiges Strommessverfahren mit hoher Temperaturunabhängigkeit zu schaffen.It is therefore an object of the present invention, a cost-effective To provide current measurement method with high temperature independence.
