Automating end-of-line quality control tests of small brushed DC motors

• Abstract:

  Robust end-of-line tests are important in manufacturing to monitor production quality and to guarantee that only fault-free products are delivered to customers. By automating quality control tests, subjectivity can be removed from this important process and traceability of defects can be improved. This paper describes a prototype station that automatically tests and classifies small brushed DC motors. In order to perform fault diagnosis, four different quantities are monitored: acoustic noise, mechanical vibration, voltage and current. A three-step approach consisting in a feature extraction phase, a feature space dimensional reduction through multivariate analysis and a final neural network classifier is proposed and preliminary results are in good agreement with experts’ assessments.
