RAPID METHODS FOR PRODUCTION LINE TESTING OF SMALL ELECTRICAL MOTORS

摘要

In order to verify quality it is not uncommon that human listening tests are used to find challenges with e.g. small electrical motors. There are many disadvantages with human ears in a production line. Hence, the need for a more objective system design has been demanded. This paper discussed a system approach enabling very rapid testing in a production line with any sensors being mounted. The system is capable in dealing with the extreme background noise and electrical and EMI noise emissions. By using the proposed design and concept, a rapid testing has been accomplished yet with a high quality. The system has been tested in a production line and verified versus a series of production line testers. The paper will discuss some of the challenges with such a system but also how these challenges have been dealt with.
