该数据为电机轴承外圈故障的数据。故障数据的采集使用朝坤测试公司的轴承加速寿命实验台，通过更换轴承外圈故障电机模拟该故障。该文件为正常电机的运行数据，用于建模异常检测模型。

This data is the fault data of motor bearing outer ring. The fault data is collected by using the bearing accelerated life test bench of Chaokun Testing Company, and the fault is simulated by replacing the faulty motor of the bearing outer ring. This file is the running data of normal motor, which is used to model the anomaly detection model.
