摘 要： Rolling element bearings are critical components in induction motors and monitoring their condition is important to avoid failures. Several condition monitoring techniques for the bearings are available. Out of these stator current monitoring is a relatively new technique. Vibration, stator current, acoustic emission and shock pulse methods (SPMs) for the detection of a defect in the outer race of induction motor ball bearing have been compared. The measurements were performed at different loads. The defect in the bearing could be detected by all the methods. Acoustic emission monitoring proved to be the best method followed by SPM when the increase in the levels of the measured parameters were compared with respect to those of healthy bearings.

滚动轴承是感应电机中的关键部件，监测其状态对于避免故障至关重要。目前已有多种轴承状态监测技术可供选择。其中，定子电流监测是一种相对较新的技术。本文比较了振动、定子电流、声发射以及冲击脉冲（SPM）方法在检测感应电机球轴承外圈缺陷方面的效果。测量在不同负载条件下进行。所有方法均能检测到轴承的缺陷。与健康轴承相比，当所测参数的水平上升程度时，声发射监测效果最佳，其次为SPM方法。
