碩士 === 國立中央大學 === 機械工程學系在職專班 === 107 === This thesis studies is providing a fast defined and prediction scheme for the Reed Frequency of vertical motors: Modeling the main structure of the motor in 3D drawing, and then use finite element analysis software (Ansys) for uncomplicated setting and processing to solve vertical and horizontal reed frequency. According to the vibration spectrum measured by the technician, the Reed Frequency of the actual motor can be obtained. Finally, the reed frequency calculated by Ansys is compared with the measured data, The error between the calculated value and the actual value can be within a certain range. If the designer can quickly build an Ansys analysis model, the designer can use the Ansys software to predictive of the reed frequency, or strengthen the structure to increase the frequency to avoid resonance in general orders. This will make the larger range in which the motor can be manufactured. In order to increase the reed frequency, some motors are designed to be short and wide. They may to change to a ling and skinny structure, and will reduce the cost and enhance product competitiveness and profits.
