Automated Functional Testing of Brushless Electric Fans in Vehicle Applications: A Data-Driven Approach

The system must be based on the analysis of the behavior of the typical parameters that characterize the operation of the sample under test, including diagnostic signals. The tests of the electric fans are performed in the company laboratories in automatic mode 24/7 thanks to an automatic recording system. The main focus of the activity will be to prepare reports on request on the progress of the test in the intermediate phases; the system must indicate to the laboratory technician which verification activities on the samples or on the set up are necessary to avoid irreversible drifts in the behavior of the samples themselves under test. For the same purpose, the system must also be able to form the basis for automatically piloting any suspensions of the test and to process predictions of the final result well in advance of the end of the test itself.
