In manufacturing facilities and equipment operations, sudden abnormal noises from motors can lead to serious issues such as equipment shutdowns and product defects. These noises vary widely—including “squeaking,” “grinding,” and “hissing”—and each has a different cause. Sources range from mechanical factors like bearing wear, insufficient lubrication, and debris ingress to electrical noise. In this article, we will explain the main causes of motor noise by type and introduce specific countermeasures. Furthermore, for engineers considering the purchase of new motors, we will provide a detailed explanation of the characteristics of coreless motors—which help prevent noise issues before they occur—as well as their advantages in terms of low vibration and low noise.   Supervised by: C.I.
