Abstract

PURPOSE:To enable a comprehensive evaluation by a method wherein sounds and vibrations of a motor are detected with a sound sensor and a vibration sensor, and the quality of the sounds is judged through BPF and RMS converters while the quality of vibrations is judged through an amplitude detector section to take a correlation therebetween. CONSTITUTION:Detection outputs of a small motor sound sensor 7 and a vibration measuring sensor 6 are amplified with amplifiers 11 and 19. The seconds undergo a frequency analysis through BPFs 12-14 to determine respective frequency components. The outputs are converted into effective value voltages with RMS converters 15-17 from the first to n-th and the quality thereof is judged at a judging section 18. On the other hand, the frequency displacement is detected in the amplitude with an amplitude detector section 20 and the quality thereof is judged at a judging section 21. Since the simultaneous measurement of sounds and vibrations is possible, the correlation therebetween is determined through a comprehensive judgement section 22 for said judgement. This enables simultaneous and continuous measurement of sounds and vibrations while allowing the judgement of the quality thereof.

Conventionally, most of the measurements of vibration and sound of small motors have been performed using human senses. This is because vibration and sound defects appear differently depending on the motor's posture, and since it is necessary to measure the motor in various postures during inspection, it is human sensual to simultaneously test for abnormalities such as vibration and noise. This is because it was excellent.

However, with automatic inspection machines, vibration and sound inspections are measured on separate stages, and must have a mechanism to continuously measure while changing the posture, which has the disadvantage of increasing costs. It was difficult to determine the correlation between motor sound and vibration defects in order to measure them.
