The test stand allows vibration-decoupled mounting of the test piece, where the vibration meter measurement head and the test piece holder are mounted on a common base plate. The vibration measurement is performed at suitable, empirically determined location of the drive at the optimum working distance of the laser. The evaluation software performs the recording and evaluation of the vibration meter data as well as the motor current for the calculation of the system rpm. From the two signals, the energy bands are analyzed using frequency analysis in the vicinity of the 1st and 2nd order of rotation. The classification of the test pieces is then carried out by comparison with a threshold value.

12M metal planetary DC motor

The system reliably identifies all noise characteristics; a test time of 17 seconds, including handling, was achieved. It was also possible to realize the necessary throughput of up to 16,000 drives per day with 8 test positions. After the positive experiences obtained with the manual noise test stand, testing within an automatic production line is now in preparation with the aim of subsequent integration in an existing assembly line. Thus, the micro drive systems can be identified/sorted automatically and reliably in accordance with acoustic standards a further contribution towards ensuring the recognized high quality
