Abstract
This paper describes a product quality check of small fan motor vibration by using rotational swing mechanism. The small fan motors are used by many electronics equipment for cooling. They are essential for present industry. But, small fan motors have been checked by inspectors who have special skills which are based upon their auditory organs and tactual senses. It is not easy that inspectors will have mastered those skills. In addition, those skills sometimes depend upon their mental and physical condition. Now, new evaluation and diagnosis method is needed. This study focused on the motion of inspector’s handwork to develop a new diagnosis method of small fan motors. In the experiments, the acceleration of small fan motor’s vibration has been measured, and the difference between maximum and minimum of the acceleration RMS level and time average value has been taken as the index to show the vibration amplitude. These results show the proposed method can be a new evaluation method for the diagnosis of small fan motor’s vibration.
