基于扩展Park矢量的电机故障诊断系统设计

摘要

Broken Bar Faults and Bearing Faults were the main faults in Asynchronous Motors. Those detection is very important in Motor Fault Diagnosis. Based on the theory of Parks Vector, a method for detecting broken rotor bars faults in asynchronous motors is presented here. With the characteristic of bearing faults and the sensor signal, design of fault diagnosis system was given in detail. Practice proves the high adaptability and wide.%转子断条故障和轴承故障是异步电动机的主要故障,这两种故障的检测是电机故障诊断的重要内容.根据扩展Park矢量法理论的原理,阐述断条故障的诊断方法,结合轴承故障特点及冲击脉冲传感器的信号,给出了异步电机故障诊断系统的设计方案.实践表明,系统具有很强适应性和广阔的工业应用前景.
