上一筆

本研究使用數值方法中的有限元素法來分析感應馬達結構強度與穩定性，此馬達在性能上額定轉矩為 7.2 N-m，而額定功率為 4.5 kW，設計使用於小型車輛上。除了分析結構強度之外，我們同時關心馬達在外力作用下轉子與定子之間間隙的變化以及在不同轉速下轉子的穩定性。根據結果顯示在目前設計下馬達在承受外力時轉子與定子之間仍可以維持良好的間隙條件且轉子最低共振頻率遠高於外力擾動峰值頻率 250 Hz 等同於轉速 15000 rpm，而因為轉子轉軸與矽鋼片是使用熱套方式進行組裝，因此我們對於工作環境溫度上升至 180 度後轉子是否仍可以輸出峰值轉矩 21 N-m 進行評估，而根據結果顯示在極端的環境下轉子使用熱套組裝是可維持正常運作的。

The structural strength and stability of an induction motor designed for small vehicles with a rated torque of 7.2 N-m and a rated power of 4.5 kW is analyze numerically using finite element method. In addition to the structural strength, special attention is devoted to issues regarding the reduction of clearance between the rotor and stator due to external loadings and the stability of rotor running at various rotating speeds. Based on the current design, it is found that proper clearance can be maintained under the action of external loads and the lowest resonant frequency of the rotor is much higher than the peak forced frequency of 250 Hz which corresponds to a rotating speed of 15000 rpm. Since the rotor is assembled via shrink fit between the axle and silicon laminates, it is interesting to determine if the shrink fit would fail when the rotor is running at the peak torque of 21 N-m and at a raised temperature of 180◦C.Ourcalculationindicatesthattheshrinkfitwillsurviveunderthecrucialconditions.
