Motor Vibrophonic Monitor

MV-90 - ECG KOKUSAI Co., Ltd. (ECG)

A very small acoustic vibration during operation can indicate a major defect in a small-sized precision motor. The acoustic vibration is normally detected using a sounding bar applied to the ear of an inspector who judges whether to reject or pass a motor by listening to its sound during operation.This method produces different judgments according to each individual inspector, and automation is not possible. With this unit, a highly sensitive acceleration-type detector is applied to the bearing area of a motor, to directly defect the acoustic vibration.The resultant measurement is not influenced by environmental noise, and an absolute and accurate measurement can be made.
