| 摘 要： | 论述了感应电动机转子故障检测基本原理,讨论了传统信号分析方法难以提取出明显的转子故障特征的原因.鉴于基于连续小波变换离散化的离散小波变换算法的运算量大,计算速度慢,提出了一种快速算法,它利用递推方法计算小波系数,运算速度快,可应用于在线实时检测.提出了基于相位信息的感应电动机转子故障检测新方法,对实测数据进行处理的结果表明,该方法能够实现感应电动机转子故障的准确检测.

| Abstract: | Rotor bar fault is one of the frequent faults of the squirrel cage induction motors. The spectrum analysis of the stator current signal based on Fourier Transform is widely used to detect the fault, but it has many disadvantages. A new approach for the rotor fault detection on line based on phase information of the complex wavelet transform is presented, and in view of the large volume calculation and low speed of the complex wavelet transform algorithm, a fast algorithm based on recurrence method is proposed to calculate the wavelet coefficients. Experimental results show that the presented approach is effective. |
