Experimental Measurements of Active Vibration Reduction via Current Injection in an Electric Motor

For each considered condition (650 and 800 rpm), two recordings of the motor under test in normal operation without current injection can be found, as well as the 25 current injection tests obtained by combining different values of amplitude and phase. For each case, an excel file with data analysis can also be found. The recordings are provided in the form of .wav files. Each .wav file has 7 channels, arranged as follows: CH1 -> Accelerometer X (Dytran, type 3233A) CH2 -> Accelerometer Y (Dytran, type 3233A) CH3 -> Accelerometer Z (Dytran, type 3233A) CH4 -> Microphone (Bruel&Kjaer, type 4189) CH5 -> Current U CH6 -> Current V CH7 -> Current W
