摘要
阐述了电梯曳引机故障的机理、故障特征；采用小波分析技术。通过对曳引机信号的分析，处理判断曳引机是否有故障存在并找出故障类型，以便及时采取措施，减少损失。
The fault mechanism and fault features of traction machine are introduced. Whether existing a fault of the elevator traction machine is determined through the analysis and processing of the traction machine signal with the wavelet analysis technology, and that the fault type is pointed out in order to take timely measures to reduce the toss.
