Motor pure sound signal and real industrial environment noise sound signal samples

The dataset contains three types of motor acoustic signal samples under different interference conditions: 1. Pure motor acoustic signal samples; 2. Acoustic samples of motors affected by noise interference from factory production lines; 3. Acoustic samples of motors affected by factory laboratory noise interference. There are four different conditions for the motor: 1. Healthy motor; 2. Magnet fracture motor; 3. Excessive Hall adhesive on the stator of the motor; 4. The bearing is too tight for the motor. Each motor collects acoustic signal samples from three different directions: left, front, and right.The collection device is divided into PCB acoustic condenser microphone and smartphone.
