Original Abstract

Abstract: - This paper deals with the fault diagnosis of a brushed DC motor used as a pump in an automotive fuel module. The jamming, direction of the rotation and the angular velocity are indirectly measured without access to the rotor. Two implemented approaches are presented. The first method uses the FFT analysis of the measured current for the estimation of angular velocity together with the load of the pump using suction. The developed test lasts min. 6 sec. and reliably detects the direction of the rotation. The second method uses a magnetic field sensor for the detection of the rotation direction. Although it provides a simpler setup and a shorter measurement time, it is also more sensitive to noise and the precise positioning of the sensor.
