105 電動機フレームの振動特性の実験評価
詳細
For the development of low vibration frame in a motor, the vibration characteristic is experimentally evaluated for frame and frame with stator core. As a parameter of affecting frame vibration, the plate thickness of the end bracket is selected. For the evaluating frame vibration, impact testing is used and transfer function is analysed by FFT analyzer. As the result, vibration amplitude of the frame at 2nd circular mode is lower, when the plate thickness of the end bracket increases.
