“…The Hall sensor transforms the magnetic field intensity into output voltage; thus, we will use a relative value representing the magnetic field magnitude expressed in volts as the external magnetic field parameter. The Hall sensor used in the automobile diagnostic represents textolite ruler, at the end of which the Hall element is located, equipped with BNC connector for connection with the oscillograph [21].…”

Evaluation of the external magnetic field parameters allows determining the technical condition of the automobile alternator with minimum labour intensity and sufficient informativity. However, measurement of the external magnetic field magnitude with Hall sensor doesn’t allow expressly recognizing an occurring fault. It has been established that the spectral decomposition of external magnetic field oscillogram significantly increases informativity of this diagnostic parameter. Indicating harmonics, which extreme value allows identifying the technical condition of the automobile alternator, are distinguished. The article materials can be used for further development and implementation of the automobile alternator diagnostics based on the parameters of the external magnetic field.

The relevance of the problem of automotive alternator diagnosis is associated with the imperfection of existing methods due to their significant complexity and lack of information. In order the accelerate the process of electrical failures diagnosis, the article considers their physical modelling method, the advantages of which are significant acceleration of the experiment, the possibility of modelling several failures, as well as the establishment of a clear boundary between the serviceable and non-serviceable states of the alternator. Adequately simulating the processes occurring in the alternator, physical modelling is implemented by means of serial or parallel connection to the alternator elements of adjustable active resistance. Experimental data show that the most informative and sensitive to the process of failures development is the temperature increase which can serve as the basis for on-board monitoring system aimed at determining the technical condition of an automotive alternator.
