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。该文件为故障电机在4000牛径向负载情况下的运行数据，共有正常样本240个，故障样本960个。

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 operation data of the faulty motor under the radial load of 4000 N, including 240 normal samples and 960 faulty samples.
