为了辨析高压电机架构内铁芯特有的松动情形，对其表层范畴内的振动信号进行了判别和调研。通过辨析振动信号，能辨别出铁芯松动特有的故障源。对铁芯松动阈值进行纵向和横向对比，可查验配件的松动端点和明确铁芯松动的方位。这种判定方法具有简易性，不用考量配件的电压更替和传感器固有的型号差异。
為瞭辨析高壓電機架構內鐵芯特有的鬆動情形，對其錶層範疇內的振動信號進行瞭判彆和調研。通過辨析振動信號，能辨彆齣鐵芯鬆動特有的故障源。對鐵芯鬆動閾值進行縱嚮和橫嚮對比，可查驗配件的鬆動耑點和明確鐵芯鬆動的方位。這種判定方法具有簡易性，不用攷量配件的電壓更替和傳感器固有的型號差異。

Analysis of the high-voltage motors for unique core architecture lose situation, its surface vibration signals were within the scope of discrimination and research. Analysis of vibration signals through, can identify the core loose peculiar source of failure. Loosening of the core longitudinal and transverse threshold value comparison, provable and clear loose core end fitting loose orientation. This determination method is simplicity, not considering replacement parts and sensor voltage differences inherent in the model.
