该数据为电机转子不平衡故障的数据。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，通过更换转子不平衡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200个，故障样本1000个。

This data is the data of unbalance fault of motor rotor. 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 rotor unbalanced fault motor. This file is the operation data of the faulty motor under the condition of 4000 N radial load, including 200 normal samples and 1000 faulty samples.
