This storage bin mainly records the open-circuit fault diagnosis data set of multi-phase converter used in the paper “XXXX” ( follow-up to the title of the paper ). It mainly includes : 1 The simulation domain data set of five-phase induction motor AA ; 2 experimental domain data set of five-phase induction motor AA ; 3 The simulation domain data set of five-phase induction motor BB ; 4 The experimental domain data set of five-phase induction motor AA under different signal-to-noise ratio interference ; 5 The simulation domain data set of dual three-phase permanent magnet synchronous motor AA ; 6 Experimental domain data set of dual three-phase permanent magnet synchronous motor AA. Each '.mat ' file in the above data set records data with a time scale of about 1s, where 0-0.5s is the health state and 0.5s-1.0s is the fault state. All the experimental domain data sets have a dynamic transition period ( fault transient ). The simulation domain data set abandons the dynamic transition period when it is constructed, which can be regarded as the ' splicing ' of the health state and the fault state. In addition, the rotor speed, load torque and category labels corresponding to each '.mat ' file in the five-phase induction motor simulation domain and experimental domain data set are stored in the corresponding Excel files.
