| 摘 要： | 为探讨高压电动机在运行时出现的电机本体振动值偏高问题的原因,将电能质量技术应用到电动机振动分析中.通过理论简析和实测数据建立了电流不平衡性与电机振动值之间的关系,提出电动机进线电流不平衡是迫使其振动值偏大的重要原因.实测数据分析结果表明,外电源进线电压不平衡是引起电机振动值偏大的直接原因之一.

| Abstract: | In order to locate the reason of abnormal motor vibration when the motor is runing,the electric power quality analysis was investigated.After an academic explanation and analysis of actual testing data,the primary conclusion that abnormal motor vibration was caused by the unbalanced incoming current was established.Lastly through simple calculation and comparison,the experimental results show that the unbalanced electric source voltage is one of the direct factor leading the abnormal motor vibration. |
