介绍了单相异步电动机轴承、定转子故障的诊断方法。所提出的方法使用声信号。分析了单相异步电动机的5种状态：正常运行状态、主副绕组短路、副绕组短路、转子断条和鼠笼环故障、轴承故障。提出并实现了一种声信号特征提取方法-- SMOFS-22-MULTIEXPANDED（Shortened Method of Frequencies Selection Multiexpanded）。实现了SMOFS-22-MULTIEXPANDED作为声信号的特征提取方法。分类步骤使用NN（最近邻）分类器进行。该方法对单相异步电动机的轴承、定转子故障诊断具有良好的效果。所开发的方法可以找到其他类型的旋转机械故障诊断的应用。(C)2018爱思唯尔有限公司版权所有。
The paper presents description of bearing, stator and rotor fault diagnostic methods of a single-phase induction motor. The presented methods use acoustic signals. Five states of the single-phase induction motor were analysed: healthy motor, motor with shorted coils of auxiliary winding and main winding, motor with shorted coils of auxiliary winding, motor with broken rotor bar and faulty ring of squirrel-cage, motor with faulty bearing. A method of feature extraction of acoustic signals- SMOFS-22-MULTIEXPANDED (Shortened Method of Frequencies Selection Multiexpanded) was developed and implemented. The SMOFS-22-MULTIEXPANDED was implemented as feature extraction method of acoustic signals. Classification step was performed using the NN (the Nearest Neighbour) classifier. The proposed methods had good results for diagnosis of bearing, stator and rotor faults of the single-phase induction motor. The developed approach can find applications for fault diagnosis of other types of rotating machines. (C) 2018 Elsevier Ltd. All rights reserved.
